Heh.  That was a non-starter, so instead, I am doing what I hoped
to avoid, merging in every delta from NetBSD one by one -- there
are simply too many changes, and the way that uaudio.c is put
together is that there's a Net/OpenBSD-specific part, and then
a FreeBSD-specific part.  Probably because of the difference
between the sound framework of them.

Many of the diffs apply to the NetBSD-specific part cleanly, but
don't apply to any FreeBSD code, so there is a goodly amount of
functionality that is being added but not for FreeBSD, yet.

I put this aside for a while, to work on something different, but
when I complete the merging, I hope to have something that contains
all the latest NetBSD code, which then needs to be manually hacked
into the FreeBSD-specific part.

That may be beyond my reach, but I hope that the merged code can
be used as a starting point by someone with the clue I lack.
Also, maybe some things will have been added by these merges to
FreeBSD as well that are presently missing in uaudio functionality.

Anyway, that's my work in progress, but no promises...

I'm actually using 4.x exclusively for reasons I won't get into
in detail (GEOM broke compatibility with my disk layout, and I
haven't taken the time to properly build 5.x and 6.x as a real
work environment for this reason), though I can cross-compile and
maybe do minimal testing on 5.x and -current -- probably, unless
my present hardware has problems with recent OS source.

So if I do come up with something, I'll announce it here for any
interested parties to build and test.  As the uaudio.c code in 4.x
is essentially identical to that in -current, I hope that whatever
I do should be applicable to all.
