Win32 port, mainly DirectX:

 * use DirectX under CygWin and basic auto-stuff
 * move some my macros in configure.ac
 * I don't know why, but shared directx plugins can't be linked with
   libdxguid.a. Used cute-hack, idea is from mplayer. Also thanks to
   hexedit, because I haven't sources of w32api.
 * Fix some warnings in vo directx and ao directx.
 * Decrease version of directx. It seems it still works.
For compilation with DirectX under Cygwin you need header files from
directx-sdk. Autoconf macros are only basic, but it works. for example:
  DIRECTX_CFLAGS=-I/cygrive/c/Program\ Files/Directx/include ./autogen.sh
