  Modified files:
    sys/dev/aac          aac.c aac_cam.c aac_disk.c aacvar.h 
  Log:
  Collapse sync fib locking into normal i/o locking.  The former didn't
  protect the registers so it was trivially possible for a sync command and
  i/o command to fight each other and confuse the controller.  Make the
  sync fib alloc/release functions inline and remove the somewhat worthless
  AAC_SYNC_LOCK_FORCE flag.  Thanks to Adil Katchi for helping me to track
  this down in RELENG_4.
