MINGW32 port. Engine library and most of plugins compiles now.

List of some changes:
 - replaced some _MSC_VER by more common WIN32
 - define INTLDIR, remove -static flag for included intl
 - shared more common CFLAGS with DEBUG_CFLAGS
 - use WIN32_CFLAGS for all building
 - separate some flags into THREAD_CFLAGS_CONFIG,
   THREAD_CFLAGS_CONFIG and ZLIB_LIB_CONFIG for public xine-config,
   automatically use internal libs if necessary
 - don't warn about missing X for mingw and cygwin
 - libw32dll disabled for WIN32 (making native loader would be
   interesting, or porting wine code to Windows? :->)
 - DVB and RTP disabled for WIN32, not ported yet
 - fix build and fix a warning in cdda
 - fix build for nosefart and libfaad
 - implement configure option --disable-freetype
 - sync libxine.pc and xine-config.in
 - add -liberty to goom under WIN32
 - move original build files from included phread and zlib into archives
   and replace them by autotools
