- Updated to Luigi's 2-15-98 code. The code in 2.2 is the same except for

  select/poll and DEVFS changes, which are limited to an include/define
  in sound.h and the actual select/poll implementation in sound.c

[ This commit is blind, but the code is similar enough that there will
  hopefully be no problems. ]
