I noticed while rereading the AD1846 datasheet last night that the
1846's 16-bit linear mode is signed, while its 8-bit linear mode is
unsigned.  All of the other codecs are probably the same way.
Aaaarrrgh.

So we add

#define AUDIO_ENCODING_ULINEAR 4

to fill up that unsightly hole between AUDIO_ENCODING_LINEAR (3) and
AUDIO_ENCODING_ADPCM (5).

That reminds me.  There are multiple ADPCM formats out there, which
does AUDIO_ENCODING_ADPCM represent?  IMA, G.722 (not sure about that
#), Creative Labs?  A bit academic because no one uses it yet.
