(svn r1827) Next iteration of the byte -> char transition: some string drawing functions and buffers

(svn r1826) -Feature: a brand new OldLoader so OpenTTD is TTD(Patch) compatible
again.. kind of anyway. Still needs work for the extra chunks
TTDPatch provides, and which we use too, but not in the same way..
- Also, no longer BE is a problem, reading is BE/LE safe.
- Tnx to Bjarni for the BE testing, Tron for the help on the BE,
Darkvater for helping out, and Mek for providing me with the correct
information regarding TTDPatch savegames

(svn r1825) Further style improvements:
- uint16 -> StringID where appropriate
- if cascades -> switch
- remove redundant ifs
- misc. stuff

(svn r1824) -Codechange: made ChangeIndustryProduction a bit more readable

(svn r1823) Get rid of some ugly cast magic concerning language packs

(svn r1822) Const correctness

(svn r1821) Move generic string handling functions to string.[ch] and introduce stre{cpy,cat}, see string.h for their semantics

(svn r1820) Style cleanup:
- indentation
- 0 -> '\0' in string handling
- whitespaces
- space after for, switch, etc.
- don't treat non-boolean values as boolean
- space before and after binary operators
- bracing style

(svn r1819) -Codechange: removed 1 unused function, and 1 unused struct (tnx to Tron)

(svn r1818) -Add: Dynamic orders (up to 64k orders)

(svn r1817) -Codechange: Moved depot-functions to depot.c
-Codechange: Added wrappers around depot-access (GetDepot no exists)
-Codechange: Made depot-functions a bit more logic (no longer
GetDepotByTile crashes your game when you request it on a non-depot tile)
-Add: made depots dynamic (yes, 64k depots are possible now)

(svn r1816) Use char instead of byte for string formatting

(svn r1815) Remove some unused declarations

(svn r1814) Let ReadFileToMem() return void* (instead of byte*) because we don't know what the caller wants to do with the data

(svn r1813) Declare functions implemented in strings.c in their own shiny new header (though i think some of these function don't belong into strings.c)

(svn r1812) [1117058] Use CT_WATER instead of CT_STEEL when accounting water which gets delivered to a town (worked because CT_STEEL and CT_WATER share the same enum number)

(svn r1811) Use char for string handling in namegen.[ch]

(svn r1810) Move town name generation declarations into a header of their own

(svn r1809) Remove unused function str_is_below()

(svn r1808) Use strcmp() instead of home brewed function str_eq()

(svn r1807) Langfile updates (20050205)

(svn r1806) Add missing includes (see r1803)

(svn r1805) Teach the driver layer a few things about const correctness

(svn r1804) Bring MSVC project files up to date (bociusz)

(svn r1803) Move debugging stuff into files of it's own

(svn r1802) Fix typos made in r1797

(svn r1801) -Fix [Multistop] Fixed a crash that occured when copying orders due to not checking a pointer to be non-NULL

(svn r1800) Make adding new debug categories to the command line parser easier

(svn r1799) -Codechange: [ Multistop ] Added debug class "ms" and more debugging
output for multistops

(svn r1798) GetFoo(i)->index is per definition i, so replace the former with the latter

(svn r1797) Clean up TileLoopClearHelper() a bit:
- if cascades -> switch
- uint -> TileIndex
- (uint)-1 -> INVALID_TILE
- don't treat non-flags as flags

(svn r1796) Revert r1792, because MorphOS has defaults for CC/CXX, they're just wrong, so setting CC/CXX using ?= simply did nothing

(svn r1795) Change CFLAGS for MorphOS (tokai)

(svn r1794) Make the dedicated server compile again under MorphOS (tokai)

(svn r1793) Revert one instance of $(shell) back to ``, because MorphOS does The Wrong Thing(tm) when date is used within $(shell)

(svn r1792) Revert r1761 and set fallback values via ?= for CC and CXX as there seem to be platforms (MorphOS) out there which don't provide some proper defaults.
Use gcc and g++ as defaults, because cc and c++ aren't available either. *sigh*

(svn r1791) Remove the remnants of CMD_DESTROY_INDUSTRY, which was removed a long time ago

(svn r1790) Make CmdPlantTree() and related functions more safe and (hopefully) more readable:
- check if end tile is on the map
- uint -> TileIndex
- if cascades -> switch

(svn r1789) -Fix: there is no need to save the index, it is done for us

(svn r1788) -Add: Made RoadStops dynamic. You can now create up to 64k roadstops.

(svn r1787) -Add: Dynamic signs (euh.. yeah, this means you can built 64k signs)

(svn r1786) -Fix: unitnumber is increased to 16bit, so now you can have up to 5000
trains in one game (instead of the 240 which was the current value).
Default max allowed vehicles per type is changed:
Trains: 500 (old 80)
Road: 500 (old 80)
Ships: 200 (old 40)
Aicraft: 300 (old 50)
(Tnx to Celestar and Darkvater for checking the patch)

(svn r1785) -Fix: space-correctness in road_cmd.c, and one wrong line from last
commit (tnx to DarkVater)

(svn r1784) -Fix: removed ClosestTownFromTile where possible, or replaced it
with _map2-data if possible (Celestar / TrueLight)

(svn r1783) -Add: Dynamic vehicles (now up to 64k of vehicles)

(svn r1782) Remove line which should've been removed in r1779 and caused map generation to hang infinitely

(svn r1781) Fix static declaration after non-static declaration of same symbol

(svn r1780) Don't clear LIBS and LDFLAGS

(svn r1779) Make the map generation code slightly more readable

(svn r1778) - Fix: [ 1115200 ] In the main menu, when starting a new game while the load game dialog is open, openttd asserts.

(svn r1777) Fix map generation for tropical and arctic landscape on larger/smaller maps

(svn r1776) -Add: Dynamic stations. You can now have up to 64k of stations

(svn r1775) -Fix: The NPF patch setting was not synced in network.
REMINDER FOR ALL DEVELOPERS:
We do have 2 patch-setting-arrays: player-based, server-based. PLEASE
put your new patch setting in the right one... thank you :)

(svn r1774) -Fix: fixed an other possible crash related to previous commit

(svn r1773) -Fix: [ 1114950 ] Game crashed sometimes when there were no industries
in the map

(svn r1772) -Fix: [ 1114100 ] Dedicated server boots again

(svn r1771) -Add: Industries are now dynamic (up to 64k industries). Generating
1kx1k maps should now be much faster, and give more than just oil-stuff ;)

(svn r1770) -Fix: Hopefully last pieces of code that are containing a station-id
(and should be an uint16, not uint8)

(svn r1769) Don't compute the same value twice, remove one function call

(svn r1768) -Codechange: Store town index in _map2 of town tiles
Moved house type from _map2 to _map3_hi for MP_HOUSE
Moved foundation and roadworks from _map2 to _map3 for
MP_STREET
This increases game speed by a factor of around 15(!) if many cities are around.
Converting an old game is done automagically, but can take a while

(svn r1767) fixed mixed declarations and code in last commit (oops)

(svn r1766) - Feature: Aircrafts will now go to the nearest hangar if the next airport in the orders do not have one (helipads)

- Fix: sometimes aircrafts would not go to the hangar even when they should. They do now

(svn r1765) -Fix: on loading, the total amount of towns wasn't reset to zero

(svn r1764) -Add: dynamic towns, you can now have up to 64k towns (let me know when
you have that amount of towns in a map ;))

(svn r1763) -Add: pool.c / pool.h: generalized routines for dynamic arrays (MemoryPools)

(svn r1762) -Codechange: renamed 'MemoryPool' to 'SettingsMemoryPool' (we need
MemoryPool for general-dynamic-arrays)

(svn r1761) Don't set CC and CXX
If somebody tried to use alternate compilers via an environment variable the assignment in the Makefile simply overwrote that.

(svn r1760) -Fix: [ 1113399 ] Game no longer crashes when right-clicking a disabled Full Load button

(svn r1759) Daily/Weekly/Monthly langfile updates

(svn r1758) Replace `` with $(shell), because the latter is only evaluated once instead of over and over again

(svn r1757) Stop the new AI from trying to build its HQ on non-existent tiles

(svn r1756) Cleanup: if cascade -> switch, uint -> TileIndex

(svn r1755) Trim trailing whitespace

(svn r1754) - Fix: you can once again load newgrf files with lots of sprites. Index wasn't reset in second run, thus counting them double.

(svn r1753) - Fix: [ 1113037 ] crash when accessing hi-scores in editor, it is now disabled.

(svn r1752) - Fix: MSVC acting up once again, as well as project file updates for the missing files.

(svn r1751) - Feature: New PathFinder (NPF).
- Supports trains, road vehicles and ships.
- Uses A* pathfinding (same codebase as the new ai).
- Currently unlimited search depth, so might perform badly on large maps/networks (especially ships).
- Will always find a route if there is one.
- Allows custom penalties for obstacles to be set in openttd.cfg (npf_ values).
- With NPF enabled, ships can have orders that are very far apart. Be careful, this will break (ships get lost) when the old pathfinder is used again.
- Feature: Disabling 90 degree turns for trains and ships.
- Requires NPF to be enabled.
- Ships and trains can no longer make weird 90 degree turns on tile borders.
- Codechange: Removed table/directions.h.
- table/directions.h contained ugly static tables but was included more than once. The tables, along with a few new ones are in npf.[ch] now. Better suggestions for a location?
- Fix: Binary heap in queue.c did not allocate enough space, resulting in a segfault.
- Codechange: Rewritten FindFirstBit2x64, added KillFirstBit2x64.
- Codechange: Introduced constant INVALID_TILE, to replace the usage of 0 as an invalid tile. Also replaces TILE_WRAPPED.
- Codechange: Moved TileAddWrap() to map.[ch]
- Add TileIndexDiffCByDir(), TileIndexDiffCByDir().
- Codechange: Moved IsTrainStationTile() to station.h
- Add: IsRoadStationTile() and GetRoadStationDir().

(svn r1750) - Feature: [ 1093261 ] Saving vehicle sorting criteria for each vehicle type (bociusz)

(svn r1749) Move the functions which calculate distances to map.[ch] and give the more meaningful names

(svn r1748) Enforce map size limits

(svn r1747) - Fix: [network] ottd should compile when networking is disabled.
- Change: change strgen project file to get rid of warning.

(svn r1746) - Feature: [GUI] [ 1107690 ] Resizable orders GUI (nzhook)

(svn r1745) Use -fno-inline when DEBUGing

(svn r1744) DEBUG and PROFILE can be used at the same time.

(svn r1743) -Fix: Multistop: Added some debug output and made sure that orphaned slots are cleared.

(svn r1742) - Fix: fixed bug introduced in r1730 where AI players had problems when building aircrafts

(svn r1741) - Fix: added IsVehicleIndex() so it's possible to protect GetVehicle() from reading an invalid vehicle index
- Fix: added check for v->type in some commands, which expects v to be a specific type

Checks like this is needed to protect network servers from people, who hack their clients to either cheat or crash the server

NOTE: if I made a mistake here it can make a function unreachable when it should be used. Here is one place to look if something weird happens

(svn r1740) -Fix: [ 1112342 ] Realistic acceleration works properly with TTDPatch non-stop handling behaviour

(svn r1739) - Fix: type checking when selling vehicles (TrueLight)

(svn r1738) -Fix: [ 1108735 ] Fixed (hopefully) an assertion that was cause by selling carriages in a MP game faster than the network can handle. (Truelight)

(svn r1737) Add DEBUG category "map" and use it to print the map size when allocating the map

(svn r1736) -Fix: Forgot to remove some unused variables in last commit :(

(svn r1735) -Fix: [ 1112285 ] Fixed an assertion error with stations where stops
were deleted, the assertions were just plain wrong at that place. Used a
more graceful handling. Todo: What happens if ALL stations in a schedule
have no suitable stop?

(svn r1734) - Fix: [ 1112253 ] hijacking of arrow keys, game also scrolled when it was out of focus (dominik)

(svn r1733) - Fix: oops "| 1" is SETBIT(x, 0), not 1 :(. Now you can remove signals again

(svn r1732) - Change: [OS/2] [ 1112148 ] Project file update (orudge)

(svn r1731) - Fix: [ 1106930 ] BugFix: placing signals with 2x1 drags workaround is completely rewritten. Also features checks for hacked/modified clients. Thanks a lot Hackykid!

(svn r1730) - Fix: Ships and Aircrafts have to be build in depots owned by _current_player (hacked client protection)
now all 4 types of vehicles have to be build in depots. Note: there is a wordaround for AI players since the AI handle aircraft building in a weird way

(svn r1729) - Fix: [ 1112469 ] Clearing land for free by reallocating HQ

(svn r1728) - Fix: now a player can only build a road vehicle in depots he owns (hacked client protection)

(svn r1727) - Fix: now CmdBuildRailVehicle() behaves correctly if DC_EXEC is set
this commit alters ai.c a little to get rid of the workaround from r1725 so AI players could still build locomotives

(svn r1726) Move an assert() because it could not catch all cases of incorrect input where it was placed

(svn r1725) - Fix: now trains can only be built in depots and you have to own the depot too (hacked client protection)

(svn r1724) Set maximum number of industries and towns to 250 each

(svn r1723) Save the map size in tiles, not number of bits

(svn r1722) -Feature: Bigger maps - anyone?

(svn r1721) -Feature: It is now possible to build multiple road stations (up to 8) on
a single station.
Thanks to: Truelight for the saveload code, Darkvater and Hackykid for
network testing and Tron for proof-reading 1500 lines of diff.

(svn r1720) - Fix: signed/unsigned warnings. Tile which is incremented/decremented every time until suitable ground is found is compared to the direction it is going in. If this wraps, return error. For this treat the tile itself as a TileIndexDiff

(svn r1719) - Fix: [installer] fix some installer problems mainly for DOS files as well as beautify it a little
- Fix: corrected newlinetype of tile.c

(svn r1718) Use the enum TileType as parameter/return type for [GS]etTileType() instead of plain int.
This makes it necessary to rename TileType() to GetTileType() because a type and a function may not share the same name.

(svn r1717) -Fix: some compilation problems for braindead VS6 and added missing files to project (thx bociusz)

(svn r1716) Prevent zeppelins from accessing non-existent tiles when leaving the map

(svn r1715) Move [GS]etMapExtraBits to tile.[ch]

(svn r1714) Add missing include

(svn r1713) Split off several functions which query/set information about a single tile from map.h and put them into a seperate file tile.h

(svn r1712) - Fix: a hacked client can no longer send other players trains to a depot

- Feature: [autoreplace] trains now tries to find a depot if they needs to be replaced

Now all 4 types of vehicles goes to a depot if they needs to be replaced

(svn r1711) - Add: [MacOSX] Added an Xcode project file (Tobin)

This project file adds a graphical IDE to OSX, including graphical debugging, which is a bit easier than gdb (Xcode uses gdb for debugging)
Since it uses the makefile to compile, it should (hopefully) work without updating the project file when the makefile is updated
Tobin did most of the work, but I altered paths and settings for custom executable so it should work out of the box for everybody

(svn r1710) - Fix: [autoreplace] vehicles do no longer go to a depot all the time if the owner clicked 'stop replacing' ( ship+aircraft+road vehicles )

(svn r1709) - Feature: [autoreplace] ships now automatically goes to a depot if they need to be replaced

(svn r1708) - Fix: FindNearestHangar() will no longer return a hangar where a jet will crash if it is a jet, that is searching
- Codechange: Since planes move in strait lines in 8 directions, GetTileDistAdv() is used instead of manhatten distance in FindNearestHangar()
