Log Message:
Update xmess to version 0.103.

Release 0.103, 16 January 2006:
- Everything from MAME 0.103 (http://x.mame.net/changes-mame.html) and
  MESS 0.103 (http://x.mame.net/changes-mess.html).
- Modified osd_alloc_executable() to use mmap() by default.  This
  prevents segfaults in the DRC core on systems that support the NX
  bit, such as AMD64 and Intel Prescott.  Thanks to Julian Sikorski,
  Adam Moss, and Carl Fongheiser.
- Fixed a segfault that occurred when LIRC was enabled but lirc_init
  returned an error value.  (Joe Quanaim)
- Added "-[no]lirc" to enable or disable LIRC support.  (Joe Quanaim)
- Fixed several buffer overruns that happened when overly-long data was
  passed for "-ctrlr", "-lang", "-rec", and \ 
"-pb".  Fixed other
  potential buffer overruns.  Bugzilla bug 821.
- Files larger than 2GB can now be accessed on platforms with large
  file support.
- The "-createhd" and "-merge" operations in chdman are now a lot
  faster on Linux.
