Update xmess to 0.95.

Changes since 0.90 includes:
- Everything from MAME 0.95 (http://x.mame.net/changes-mame.html) and
  MESS 0.95 (http://x.mame.net/changes-mess.html).
- Forcing Xv to use YV12 ("-force-yuv 2") no longer causes rotated
  games to segfault.  Fixes Bugzilla bug 679.
- Fixed the aspect ratio of the MESS SuperVision driver so that it's
  quadratic.  (PeT)
- Fixed several problems with the front-end "-list" commands: The MESS
  commands could segfault, some commands' headers were misaligned, and
  "-listpalettesize" was causing the ROM list to print.
- Worked around or fixed a double-free on exit in xmess.
- Fixed a segfault on startup that occurred when four or more joysticks
  devices were found.
- The SDL joystick driver now works with multiple joysticks attached.
- The SDL sound driver should produce much better output.  Also fixed a
  potential deadlock.
