Update xmame to 0.61.1.

Changes since 0.60.1 include:
- Almost everything from MAME 0.61 and MESS 0.61.2.
- Fixed the register constraints in cpu/i8085/i8085cpu.h so that
  cpu/i8085/i8085.c can build for x86 using gcc-3.1 with -O3.  This
  change was missed in the MAME 0.61 release.
- Increased the size of the buffer used to display history.  (Steve Fewell)
- Modified unix/fronthlp.c so that it flushes its output more often to
  aid frontends.  (Shadow Walker)
- Changed unix/video-drivers/xfx.c to be more frontend-friendly.
  (Benoit Dumont)
- You can now specify a config subdirectory name using -cfgname/-cn.
  This is useful for creating an alternate configuration.  (Benoit Dumont)
- Added a "waveout" DSP plugin which redirects sound to a file using
  Microsoft's PCM WAVE format.  The file name can be specified with the
  "-audiodevice" switch and defaults to "xmameout.wav".  \ 
(Donald King)
- Added support for showing average frames per second when quitting.
  Also added support for the -frames_to_run/-ftr switch.
- Added Xv hardware scaling support!  To enable, uncomment the line
  reading "X11_XV = 1" in the makefile and use the -xvext/-xv switches
  (and possibly the -yuv switch).  (Alastair Robinson)
- An X11 build can now grab the keyboard to bypass window managers.
  Use -grabkeyboard/-gkb to activate and/or the ALT + PGUP keypress to
  toggle it on/off.  (Gerd Sussner)
- The code for finding the best X11 visual now checks in descending
  order of bit depth.  This is to work around a bug/feature in the
  latest NVidia drivers.  (Gerd Sussner)
- Fixed a problem in the DGA2 driver that could lead to scrambled
  colors with an i830MG video card in 24bpp mode.  (Eric Brunet,
  Shyouzou Sugitani)
