Subject: *BUGFIX* 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

CVS patchset: 7709
