Updated darcnes to 2000-02-19.

Changes:
o Unified cd_freebsd.c and cd_linux.c into cd_unix.c.
o Added support for NetBSD CDROM (untested), and sound interfaces
  (thanks to Thomas Klausner for the NetBSD changes).
o Changed the nes bank 4 and 6 I/O hooks.
o Fixed FDS mapper to compile again.
o Fixed some problems with the PCE timer.
o Changed the PCE VDP interface not to use procpointers.
o Added clipping sprites to the right side of the screen to the PCE VDP.
o Removed the old (disabled) ROM type identification routine.
o Fixed the battery file handling to not use a cheap hack to get the
  filename (this breaks all gg savegames until you rename the battery
  file).
