loader.8: Document module commands
Begin documenting module loader commands in loader(8), where the reader
would look for them. Segregate them by their availability in individual
loader implementations, like build(7) targets.
These details were graciously donated by kevans.

loader manuals: Clarify console and boot_serial
console=comconsole is for the loader and boot_serial is for the kernel.
I think we should centralize documentation on the loader settings in one
manual, such a loader.8. The current proliferation is not obvious where
to find the documentation. To the user, these are all set in loader.conf
or at the loader prompt.

sound: Merge chn_intr() with chn_intr_locked()
There is no scenario where chn_intr() is called with the channel lock
already held.
No functional change intended.

sound: Merge PCM_ALIVE() with PCM_REGISTERED()
PCM_ALIVE() is used only in pcm_unregister(), but it does not hurt to
use PCM_REGISTERED(), which uses PCM_ALIVE() internally. In fact, it's
more robust this way.

sound: Retire snd_mtx* wrappers
Do not create mutexes with snd_mtxcreate(). It doesn't provide any
value, plus it first allocates the mutex with malloc(9). Allocate
mutexes in the stack and use mtx_* functions directly instead of the
snd_mtx* wrappers.

sound: Simplify logic in dsp_io_ops()
Use CHN_LOCK()/CHN_UNLOCK() directly, instead of
dsp_lock_chans()/dsp_unlock_chans(). These functions are useful when we
want to potentially lock both channels. Here we know which channel we
are locking, so we can just lock it directly. This way we get rid of the
prio variable as well.
Related to runpid again, there is no reason to assign it when
CHN_F_RUNNING is not set. channel->pid (as well as channel->comm) is
always assigned in dsp_chn_alloc().
Get rid of runpid. I do not see how we can end up with channel->pid
(td->td_proc->p_pid) not matching buf->uio_td->td_proc->p_pid.
Also improve errno values.

dmesg.8: Index kern.msgbuf_show_timestamp
This is the only place this important debugging tunable is documented.
Mark it up with the Va macro according to style.mdoc(5) so that people
can find it via `apropos Va=kern.msg`, the standard syntax to search
the FreeBSD manual for sysctls and tunables.
