Modified Files:
        src/sys/dev: audio.c audiovar.h

Log Message:
Add latency sysctl to adjust hw blocksize and hence latency of the mixer.

        usage: sysctl -w hw.hdafg0.lantency="value in milliseconds"

It is possible to set the latency of the mixer unless a static blocksize
is configured by the underlying hardware driver (pad, vcaudio on RPI).

Documentation updates to audio.4 will occur in a follow up commit.

OK christos@.  XXX pullup-8.
