src/sys/dev/sound, branch release/5.2.1

Partial MFC of revision 1.16.

2004-02-15T00:15:44Z

Change KASSERT() in feed_vchan16() into an explicit test and call to panic() so that the buffer overflow just beyond this point is always caught, even when the code is not compiled with INVARIANTS. This will cause a deterministic panic if a particular combination of sound hardware and client software triggers the buffer overflow in the vchan code. This is better than letting the system panic in some unrelated part of the kernel because of heap corruption.

The thread waken up can run at a priority as high as after tsleep(). - Replace selwakeup()s with selwakeuppri()s and pass appropriate priorities. - Add cv_broadcastpri() which raises the priority of the broadcast threads. Used by selwakeuppri() if collision occurs. Not objected in: -arch, -current
