janwas 0bb0df5b2c # new year's cleanup (reduce dependencies, clean up headers)
- 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.
