Subject: audio: make internal audio format 0 an invalid format

Having to use -1 for that is generally quite annoying.

Audio formats are created from bitmasks, and it can't be excluded that
0 is not a valid format. Fix this by adjusting AF_FORMAT_I so that it
is never 0. Along with AF_FORMAT_F and the special formats, all valid
formats are covered and guaranteed to be non-0.

It's possible that this commit will cause some regressions, as the
check for invalid audio formats changes a bit.
