Pull up following revision(s) (requested by isaki in ticket #910):

        sys/dev/audio/audio.c: revision 1.49
        sys/dev/audio/audio.c: revision 1.61
        sys/dev/audio/audio.c: revision 1.66
        sys/dev/audio/audio.c: revision 1.67

Move #if DIAGNOSTIC..#endif to correct place.
It should ignore stray interrupts regardless of DIAGNOSTIC.

Improve an error message about round_blocksize.

Improve diagnostic messages.

Improve the blocksize notation.
The blocksize is expressed in bytes, and the millisecond notation
is supplementary information to make it easier to understand.
