Windows ports fixes and improvements due to my current work on toxine:
- first experiments with external win32 pthreads,
  more portable code (pthread_t may be a struct)
- headers refactored
- moved dirent win32 replacement to lib/, hide it for frontends,
  used system version, if found, not used non-POSIX dirent->d_reclen
  (this item doesn't work in MinGW), fix memleak in dvb
- separated settings for postproc and avcodec when using external ffmpeg
- check for malloc.h in public xine.m4, used it conditionally in xine headers
- replaced random() by POSIX more common rand()
- prevent one segfault in directx vo plugin, if fails
- M$VC port update

 - use replacement functions (macro AC_REPLACE_FUNCS and variable LTLIBOBJS),
   each function is in a file placed into lib/ directory,
   it was not necessary, but it looks nice, IMHO
 - headers cleanups (this was needed):
     - prototypes of replacement funtions and macros are placed
       into separate os_internal.h (and included by config.h)
     - drop include inttypes.h from public xine.h, replaced by custom
       os_type.h, idea origins from Ogg/Vorbis public headers
     - disable generating inttypes.h: generated replacement isn't enough for
       xine-lib but nobody complained (and for M$VC we have special version)
     - better including headers for win32, let dvdnav use its mutex wrapper
 - updated M$VC port
Result:
  - xine is compiled nicely by MinGW, CygWin and paritaly M$VC
  - frontends in M$VC port don't require additional helping headers
  - moved some platform specific things from xine-utils and win32/contrib
    to lib/
Finally I can start with real coding. :-)
