audio/oggdec: wait for pcmconv child process to exit
...
we have to wait for the pcmconv process to exit before
exiting yourselfs because otherwise pcmconv could
keep /dev/audio open and prevent further reopens for
a short period of time.

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.

really is MAD_F_FRACTBITS + sign bit and rest used
for overflow.
