these are required by thesis and improve 0ad code.
- sysdep/win init/shutdown mechanism is now better documented and
survives clever vc8 optimization
- moved some extern declarations from win_internal into separate headers
main: remove debug_filter_add("LOADER") - was for my debugging
convenience
This was SVN commit r4752.
- remove headers always included from PCH
- nommgr.h is only included ifdef REDEFINED_NEW (allows leaving out the
mmgr stuff)
- in lib/*.cpp, moved the corresponding include file to right behind the
PCH (catches headers that aren't compilable by themselves)
- byte_order no longer depends on SDL
- add debug_level (another means of filtering debug output; needed for
thesis)
- split posix stuff up into subdirs (lib/posix and sysdep/win/wposix).
makes including only some of the modules (e.g. sockets, time) much
easier.
This was SVN commit r4728.
