audio encoding conversion cleanup

- the endianness of the conversions don't depend on the endianness
  of machine the conversions are built on, but the endianness of the
  audio data itself.  choose encoding conversions explicitly, instead
  of relying on #defines based on the endianness of the machine.
- replace home-grown conversions with comparable conversions in
  auconv.c and mulaw.c
- use the proper conversion for ulinear_be:16 -> slinear_le:16 in
  auixp(4)

thanks ajacoutot@ and sthen@ for !x86 testing
