(svn r7834) -Codechange: cleanup the includes of network/core a little; include headers in headers when the header needs types/constants defined in them.

(svn r7833) -Fix (r7829): forgot to add debug.h to the includes.

(svn r7831) -Codechange: [NewGRF] Do not mark as unsafe those NewGRFs that set their own parameters (via action D) and/or change only bridge sprite table layouts (action 0, property D).

(svn r7830) -Codechange: let NetworkCoreInitialize return a bool, so we have to set _network_available only once.

(svn r7829) -Codechange: move the network (core) initialization/shutdown functions into network/core, so the can be reused in the masterserver_updater.

(svn r7825) -Codechange: make NetworkUDPClose close a single UDP socket. Use NetworkUDPStop to close all opened udp sockets (those were called NetworkUDPClose).

(svn r7823) -Fix (r7384 / r7368 / r3757 / r7388): News windows could still cause crashes because
DeleteVehicleNews shuffles around _news_items which can wreak havoc with the NewsItem*
of a currently open news window. While here also correctly update _current_news and
_forced_news for the same reasons. Should really work now.

(svn r7821) -Fix: be more strict about the socket from where packets arrive. Do not accept requests about the game server on the master/client socket, do not accept master server acks on the client/server socket, etc.
