kernel debugger.  Proper use of these registers allows setting
hardware watchpoints for use in kernel debugging.

e47dc3a01a don't flag the playback hardchan as busy on devices with only one of them. 
if a device has vchans already but they are all busy, allocate another one
at open() time, up to a maximum of hw.snd.maxvchans.

when creating/destroying vchans, don't make/remove a devnode for the
first/last one as it replaces a hardchan.

97220dbd1e - Add trylock variants of shared and exclusive locks. 
- The sx assertions don't actually need the internal sx mutex lock, so
  don't bother doing so.
- Add a new assertion SX_ASSERT_LOCKED() that asserts that either a
  shared or exclusive lock should be held.  This assertion should be used
  instead of SX_ASSERT_SLOCKED() in almost all cases.
- Adjust some KASSERT()'s to include file and line information.
- Use the new witness_assert() function in the WITNESS case for sx slock
  asserts to verify that the current thread actually owns a slock.

e58c0d25fb - Add a new witness_assert() to perform arbitrary locking assertions. 
- Clean up the KTR tracepoints to be slighlty more consistent and useful
- Fix a bug in WITNESS where we would recurse indefinitely and blow the
  stack when acquiring Giant after sleeping with a sleepable lock held.

f4029cf62b - Always use the proc lock of the task leader to protect the peers list of 
processes.
- Don't construct fake call args and then call kill().  psignal is not
  anymore complicated and is quicker and not prone to locking problems.
  Calling psignal() avoids having to do a pfind() since we already have a
  proc pointer and also allows us to keep the task leader locked while we
  kill all the peer processes so the list is kept coherent.
- When a kthread exits, do a wakeup() on its proc pointers.  This can be
  used by kernel modules that have kthreads and want to ensure they have
  safely exited before completely the MOD_UNLOAD event.

  contents of a0, a1, and a2 to make debugging of nested traps that
  panic before displaying any useful output easier.
