fix check_available_write_cb buffer-growing logic

add an empty bin/cache dir

added support for libcurl to configure

change the value of NETWORK_NEWGRF_MASTER_API

fix the error reporting for DOWNLOAD_AVAILABLE, and change NewGRFDownload to take a NetworkGameInfo instead of the GRFConfig** - it updates the compatible/not compatible state.

scan for tarfiles in CACHE_DIR, remember what Subdirectory a tar was found in, set the GCF_FLAG on GRFs loaded from there, and hide those in the NewGRF GUI

error messages, typos/omissions, and it can now actually download the .tar into cache/<GRFID>-<MD5SUM>.tar

a working CheckAvailableNewGRFs that does a metadata search/retreival via HTTP for a given list of GRFs

set the GRFConfig's next ptr to NULL

have ShowNewGRFDownload make a copy of the GRFConfig list containg only the relevant GRFConfigs

added a GCS_AVAILABLE status, and changed the colours used in the download GUI

create the newgrf download GUI (mostly by copy-pasting from newgrf_gui.cpp) - compiles, needs testing

Add a "NewGRF Download" button to the server browser that's shown when there are incompatible NewGRFs

add a .hgignore

(svn r13729) -Fix: assumption that non-north tiles of a house do not have the 1x1 building bit set was flawed with some NewGRFs. This caused the amount of houses to differ, which causes the town radii to differ, which causes desyncs when towns are expanded.

(svn r13728) -Codechange: define DEBUG as an empty block so compiler warns us less

(svn r13727) -Fix (r13375): compilation with NO_DEBUG_MESSAGES was broken

(svn r13726) [NoAI] -Add: AIVehicle::ReverseVehicle (Yexo)

(svn r13725) [NoAI] -Fix r13723: yexo ducks

(svn r13724) [NoAI] -Fix r13723: in this modern world with all those checks and warnings GCC can give when ever I not ask him to, it fails to see the simplest of all, 'if (cargo_id == cargo_id)'.. makes you wonder, doesn't it? Well, such is life, wondering wondering wandering .. Status Quo, Yeah! Oh yeah, what was I doing ... ah, yes: don't compare one variable with itself, it is always true.. Obiwan by Yexo. (Yexo)

(svn r13723) [NoAI] -Add: added AIIndustry::GetStockpiledCargo() (Yexo)

(svn r13722) [NoAI] -Add: AICargoList_IndustryNNN (Yexo)

(svn r13721) -Codechange: one less multiplication for colour mixing in 32bpp blitters (GeekToo)

(svn r13720) -Fix (r13715): string wasn't correctly passed to draw function.

(svn r13719) -Codechange: rename IsValidPlayer to IsValidPlayerID in line with all other structs/classes that are in a pool.

(svn r13718) -Fix: possible desync on the autorenew settings 20+ game years (i.e. 4.5+ hours) after a company was started.

(svn r13717) -Codechange: place the whole 'create new company' command in #ifdef ENABLE_NETWORK as it may only be executed when we are playing in a network game.

(svn r13716) -Fix [FS#2144]: any player could construct new companies.

(svn r13715) -Fix [FS#2129]: C-like strings had to be rebound each time they were printed, otherwise the text could change due to the few number of slots that could be used to bind.
-Codechange: remove all BindCString and related functions and replace it by RAW_STRING which prints the C-string raw pointer that is on the 'print stack'.

(svn r13714) -Fix: remove the unique_id from the message that a client has joined as it is only exposes the unique_id more than needed. Patch by dih.

(svn r13713) -Fix: possible crash on creating a network packet.

update tags

(svn r13712) -Fix: enforce the length restrictions of company and president name in the commands too.

(svn r13710) [0.6] -Prepare: for 0.6.2-RC1.

(svn r13709) [0.6] -Backport from trunk: language updates.

(svn r13708) [0.6] -Backport from trunk:
- Fix: Possible buffer overflow in string truncation code (r13700)
- Fix: Handle SETX(Y) properly when truncating a string instead of ignoring it and returning a too long string (r13699)
- Fix: In some cases the (sound) mixer could overflow causing artefacts in the sound [FS#2120] (r13695)
- Fix: Do not rely on .tar files always ending with a block of zeros (r13693)
- Fix: Make sure a command is ran in the context of autoreplace or not (r13691)

(svn r13707) -Update: WebTranslator2 update to 2008-07-16 01:21:36

spanish - 3 fixed by eusebio (3)
swedish - 4 fixed by daishan (4)
ukrainian - 2 fixed by mad (2)

(svn r13706) -Fix (r13695): Small typo.

(svn r13705) -Codechange: Define and use BridgePieces enum, which will remove a few more magic numbers

(svn r13704) -Fix: make timetables work more sensible when used in conjunction with conditional orders, i.e. make it possibly to tell how long to travel to the next destination if you jump.

(svn r13703) -Update: the other language files due to a few changed strings in r13702.

(svn r13702) -Fix: do not overflow the order/timetable window when 'long' orders are displayed.

(svn r13701) -Codechange: add some more info in crash.log

(svn r13700) -Fix: possible buffer overflow in string truncation code.

(svn r13699) -Fix: handle SETX(Y) properly when truncating a string instead of ignoring it and returning a too long string.

(svn r13698) -Fix (r13697): MorphOS compilation.

(svn r13697) -Feature: Add some support for symbolic links in .tar files.

(svn r13696) -Fix[GUI]: The Build button of the vehicle list is now hidden, instead of just disabled. It will be only visible when called from the Depot Building Window.
Less confusion, hopefully. Suggested by Eddi.

(svn r13695) -Fix [FS#2120]: in some cases the (sound) mixer could overflow causing artefacts in the sound.

(svn r13694) -Change: make it more explicit that you've opened the available train/ship/etc. list instead of the one where you can actually build vehicles by setting the appropriate title for the window.

(svn r13693) -Fix (r11106, r11117): Do not rely on .tar files always ending with a block of zeros.

(svn r13692) -Fix (r13674): loading PNG sprites could very quickly fill the sprite cache.

(svn r13691) -Codechange: make it easier to determine whether a command is ran in the context of autoreplace or not

(svn r13690) [0.6] -Backport from trunk:
- Fix: Bus/truck forgetting go-to-depot order when entering a non-drivethrough road stop [FS#2117] (r13664)
- Fix: Only the front of a RV would be considered when determining to what cargos a vehicle can be refitted instead of all cargos [FS#2109] (r13622)
- Fix: RVs continueing onto next DT station when they are build adjacent to them [FS#2040] (r13581)

(svn r13689) [0.6] -Backport from trunk:
- Fix: Server crashing when banning the rconning client (r13661)
- Fix: Incorrect usage of strtoul (r13508)
- Fix: Crash when one tries to raise the nothern corner of MP_VOID tiles (i.e. the southern corner of the tiles on the southern map edge) in the scenario editor [FS#2106] (r13624)
- Fix: Division by zero when one would press 'd' (skip order) when there's no order (r13409)

(svn r13688) [0.6] -Backport from trunk:
- Fix: If the first bridge can not be build for a given length, then none of the other bridges can. Effectively meaning that if someone replaces the first bridge with a bridge that can be only 3 tiles longs then only other bridges that can be 3 tiles long will be buildable, but only if they are 3 tiles long [FS#2100] (r13611)
- Fix: [OSX] 10.5 failed to switch to fullscreen (r13584)
- Fix: Properly count number of non-north housetiles [FS#2083] (r13518)
- Fix: Drawing of zoomed out partial sprites could cause deadlocks or crashes (r13502)

(svn r13687) [0.6] -Backport from trunk:
- Fix: Signals were not updated correctly when a player removed a non-existing track piece (r13626)
- Fix: Signal states could be propagated through waypoints built in orthogonal axis (r13589)
- Fix: Track was not removed on company bankrupcy when there was a ship on lower halftile (r13488)
- Fix: Let ships also navigate on half-tile sloped watery rail tiles (r13485)

(svn r13686) [0.6] -Backport from trunk:
- Fix: Memory leak when NewGRFs got forcefully disabled and they defined GOTO labels (r13675)
- Fix: Crash when drawing a non-real sprite caused by NewGRF interference [FS#2127] (r13674)
- Fix: Disable static NewGRFs when non-static NewGRFs query them in the context of network games. This makes it impossible for static NewGRFs to disable non-static NewGRFs and 'bad' things happening because the non-static NewGRF doesn't know about the static NewGRF (r13576)
- Fix: First determine where to *exactly* build a house before asking a NewGRF whether the location is good instead of possibly moving the house a tile after the NewGRF said the location is good (r13489)
- Fix: Do not crash when resolving vehicle sprite groups with zero sprites (r13397)
- Fix: In the purchase list, CB36 for capacity was not called for the first part of rail and road vehicles (r13385)

(svn r13685) [0.6] -Backport from trunk:
- Fix: In the case that elrails and 'realistic' acceleration are disabled all electrified engines would have no power on load, until the vehicle got turned around, loaded or got into a depot [FS#2102] (r13681)
- Fix: Saving TTD imported games in recession failed due to wrong (and unneeded) type conversions in the saveload code [FS#2131] (r13679)
- Fix: Inactive companies from old (TTD) saves could be marked active in some cases, which then loads garbage in their statistics and such [FS#2126] (r13676)
- Fix: Desync when building electrified trains on a dedicated server that was started with electrification disabled [FS#2122] (r13673)
- Fix: Clear the memory for the new AI during the loading of a savegame so it does not try to execute commands generated in a different savegame, which could be resulting in the AI trying to give orders to stations that do not exist (r13505)
- Fix: Loading of very old OpenTTD savegames was broken (r13373)

(svn r13684) [NoAI] -Sync: with trunk r13599:13683.

(svn r13683) -Codechange: privatize a function that is not used outside of the class who calls it

(svn r13682) -Codechange: -Codechange: remove a now useless variable(dih).

(svn r13681) -Revert (r13678, r13677): the fixes didn't work in all cases (assertions on savegame loads).
-Fix [FS#2102]: but now in a hopefully beter way.

(svn r13680) -Fix: NPF crashing when a ship tried to find a nearby depot when on an aqueduct.

(svn r13679) -Fix [FS#2131]: saving TTD imported games in recession failed due to wrong (and unneeded) type conversions in the saveload code.

(svn r13678) -Fix (r13677): electric trains from pre elrail savegames would get stopped on load.

(svn r13677) -Fix [FS#2102]: in the case that elrails and 'realistic' acceleration are disabled all electrified engines would have no power on load, until the vehicle got turned around, loaded or got into a depot.

(svn r13676) -Fix [FS#2126]: inactive companies from old (TTD) saves could be marked active in some cases, which then loads garbage in their statistics and such.

(svn r13675) -Fix: memory leak when NewGRFs got forcefully disabled and they defined GOTO labels.

(svn r13674) -Fix [FS#2127]: crash when drawing a non-real sprite. The drawing of the non-real sprite is caused when two NewGRFs replace the same sprite and the first replaces it with a real sprite (and thus assumes it remains a real sprite) and the second replaces it with a non-real sprite. OpenTTD already looked at whether the sprite to load should be seen as a real or non-real sprite, but it failed to replace non-real sprites with a substitute real sprite when getting the sprite from the cache.

(svn r13673) -Fix [FS#2122]: desync when building electrified trains on a dedicated server that was started with electrification disabled.

(svn r13672) -Fix(r13670): silent warnings that MSVC did not raised. Looks like enums can not be easily matched :(

(svn r13671) -Cleanup: Zeros for sell.

(svn r13670) -Codechange : Merge some very alike events handlers.

(svn r13669) [NoAI] -Fix: allow clients only to join non-AI controlled companies in multiplayer

(svn r13668) [NoAI] -Add: execute 'game_start.scr' on game-start or scenario load, to allow you to load AIs on game-start
[NoAI] -Fix: -vnull acts a bit more like a dedicated server, to avoid weird complexity on several places

(svn r13667) -Documentation: Comment 'tgp.cpp' a bit. Based on patch by CommanderZ.

(svn r13666) [NoAI] -Fix: benchmarked and set the default opcodes-till-suspend to a much higher value. Benchmarks show that this value should be relative unnoticable on any 'recent' hardware (read: 5 years or newer), under normal conditions.

(svn r13665) -Fix[FS#2119]: Wrong PlayerID used for sending a message to.Patch by Yexo

(svn r13664) -Fix [FS#2117]: bus/truck forgetting go-to-depot order when entering a non-drivethrough road stop.

(svn r13663) -Codechange: Use a default parameter, hoping to reduce the different signatures of functions in menus

(svn r13662) -Fix [FS#2113]: crash when adding conditional orders to ships.

(svn r13661) -Fix: server crashing when banning the rconning client.

(svn r13660) [NoAI] -Fix: Is(Tunnel|Bridge)Tile could cause asserts (spotted by Yexo and ST_)

(svn r13659) [NoAI] -Fix: give regression a bit more time to do his job, as the new scheduler makes it take too long ;)

(svn r13658) [NoAI] -Fix r13656: to maintain savegame compatibility with trunk, don't allow setting max_opcodes, but force it to value 4000.

(svn r13657) [NoAI] -Fix r13654: forgot to update regression

(svn r13656) [NoAI] -Add: added suspend control. If an AI consumes N (default = 4000) opcodes, a sleep is forced (for 1 tick). This to give fair play for all AIs. Also, an infinite loop won't hang the GUI of the player. (Morloth)

(svn r13654) [NoAI] -Change [API CHANGE]: moved AISetting::SetCommandDelay to AIController::SetCommandDelay, as it was silly to have it in a seperate class, while it was part of the controller.

(svn r13653) [NoAI] -Fix r13652: nice typo

(svn r13652) [NoAI] -Fix: throw thread-exit-signal with a custom class, not with the value '0', which might be captured by a lot of other layers

(svn r13651) [NoAI] -Fix: SUSPENDED state can be STOPPING state too in some cases, which made debugging slightly harder .. don't 'cheat' like that, and split the ambiguous SUSPENDED into unambiguous SUSPENDED and STOPPING

(svn r13650) [NoAI] -Fix: don't segfault if you type just 'stop_ai'

(svn r13649) -Codechange: Split the GfxFillRect() special flags from 'color' into their own parameter.

(svn r13648) -Cleanup (r5303): Amplitudes should be amplitudes and not amplitudes/16.

(svn r13647) -Codechange: replace MAX_UVALUE() for std types with the equivalent constant

(svn r13646) -Change: typos and miss-aligned enum values

(svn r13645) -Codechange: Convert a macro into an inlined member function.

(svn r13644) -Fix(r13643): compare an apple with an apple. MSVC seems to not care, but some other compilers do.
Thanks to glx :)

(svn r13643) -Codechange: Enumify some loosely related values been used in the toolbar resizing processes

(svn r13642) -Documentation: Add the enum values to the widget arrays, in concordance with code style

(svn r13641) -Fix: Misleading enum name.

(svn r13640) -Codechange: make colours behind not fully solid objects less darker for BM_TRANSPARENT (for 32bpp blitters)

(svn r13639) -Codechange: rewrite 32bpp-anim and 32bpp-optimized drawing and encoding so it uses similiar scheme as 8bpp-optimized
All zoom levels are stored and a kind of RLE is used. Together with further changes and reducing number of variables, drawing is ~50% faster in average.

(svn r13638) -Fix: signed/unsigned warning for MSVC9 and gcc2

(svn r13637) -Update: WebTranslator2 update to 2008-06-25 23:36:50

(svn r13636) [NoAI] -Add: added AIGroupList, to list your groups (Yexo)

(svn r13635) [NoAI] -Fix: minor typo (Yexo)

(svn r13634) -Codechange: Let house var 0x65 ignore the house, the variable is queried for.

(svn r13633) -Fix: restoring 'service at depot X' orders from the order backup failed.

(svn r13632) -Codechange: Use 'void *' for user-data of CircularTileSearch().

(svn r13631) -Fix (r13618): forgot #define avoiding multiple inclusions

(svn r13630) -Update: apply english.txt changes from r13628 to other languages

(svn r13629) -Fix [FS#2108](r13603): diameter != radius

(svn r13628) -Feature: enable building of aqueducts in the scenario editor
-Codechange: related to this split the waterway based buttons from the landscape generation window

(svn r13627) [NoAI] -Fix: typo in word 'nuclear' (Finaldeath)

(svn r13626) -Fix (r11871): signals were not updated when player removed signals from nonexistent track sharing bits with existing track
So disallow removing signals from nonexistent track

(svn r13625) [NoAI] -Fix: re-introduce the About button in the last menu, to make Yexo really really happy again :)

(svn r13624) -Fix [FS#2106]: crash when one tries to raise the nothern corner of MP_VOID tiles (i.e. the southern corner of the tiles on the southern map edge) in the scenario editor.

(svn r13623) -Codechange: only show the 'load' of articulated RV parts that have a capacity instead of showing 'empty' parts when a vehicle is completely full.
