* dvdcss_readv optimisations for Win32. We now send only one read command
   to the DVD drive for the whole iovec.
 * Fixed _win32_dvdcss_aread to work around the WinASPI32 64kb transfer
   size restriction.
 * New and theoretically better Win32 pthread implementation which fixes a
   problem I was having when changing title on a DVD (netlist related).
   vlc_cond_multicast may or may not work.
 * Fixed the "quit" event handling in directx/vout_events.c.
 * dvd_ifo.c now takes into account error messages from UDFFindFile.
 * Temporarily disabled aout_Probe() in aout_SDL (this function
   is creating an awful lot of problems - libSDL bug ).
