pcmconv: revert previous change, fix dither clipping
...
previous change had forgot how dithering works... m(
we *really* add a random signal when *reducing* the number
of bits. just make sure we do not overflow like in
mixin().

pcmconv: fix dither clipping
...
the check in dither() was inverted. we should only
add noise when the output bit count is greater
than input bit count (samples shifted up) to
fill the lower zero bits produced by the shift.

audio: replace µlawdec, add big endian and µlaw audio formats to pcmconv, µlaw in wav support
...
to support µ-law audio embedded in wav and big endian pcm
in sun audio files the µ-law and a-law and big endian integer
decoding was added to pcmconv. sundec now parses the sun
audio header supporting stereo now.

audio: fix broken write() size for mp3dec/oggdec/flacdec
...
they accidently wrote additional bytes in the stream. this
confused the new audio/pcmconv (now actually checking
if it got complete samples).

audio: add audio/pcmconv program
...
instead of duplicating resampling and pcm format
conversion code, put it in the new pcmconv program.
