Improves quality by not squeezing 32 bit samples down to 16 bit, and
then back to 32 bit floating point.  Reduces CPU usage by skipping a
conversion step.

If there are multiple pages, the last partial page must be flushed.

Eliminate the evil goto.

This is necessary for Ogg packets that span more than one page.

We can only check for negative values if the variable is signed.

Make sure the file header gets written at the beginning, before
_write() gets called.

Move the raw buffer to struct shout_data.

Make it a local variable instead.

main.c has been renamed to Main.cxx.

Implements Mantis ticket 0003340.

Internally the vorbis (non-Tremor) decoder is working in floating
point, and it's not really necessary to cut the output back to 16-bit
if the soundcard or OS supports higher resolution.

The decoder can be trivially modified to bypass its internal
quantisation and produce floating-point output, and a separate
quantisation can be used as appropriate to the platform.

Call decoder_get_command() before doing anything else.

This lives in protocol/result.h now.
