Warner Losh e04ed822be o Return ai_batteries as 0xffffffff instead of -1. This is a nop change, but
placates gcc which seems to like to complain about -1 being assigned to
  an unsigned value.  It is well defined and intended, but since signess bugs
  are being hunted just change to 0xffffffff.
o Mask the lower 8 bits, not the lower 4 bits for the ai_capabilities word.
  All 8 bits are defined and the 0xf was almost certainly a typo.
o Define APM_UNKNOWN to 0xff for emulation layer.
