cons: Add boot option to mute boot messages after banner
This is useful for embedded systems, where it provides feedback that the
kernel has booted, but avoids printing the probe messages. If both
mutemsgs and verbose are set, verbose cancels the mute.
Additionally, this unmutes the console on panic, so a user can see what
happened leading up to the panic.

PORTVEC obtained from the firmware is the authoritative source of this
information, and nports (calculated from PORTVEC) is available by the

Fix new users of MAXPHYS and hide it from the kernel namespace
In cd8537910406, kib made maxphys a load-time tunable. This made
the #define MAXPHYS in sys/param.h almost entirely obsolete, as
it could now be overridden by kern.maxphys at boot time, or by
opt_maxphys.h.
However, decades of tradition have led to several new, incorrect, uses
of MAXPHYS in other parts of the kernel, mostly by seasoned
developers. I've corrected those uses here in a mechanical fashion,
and verified that it fixes a bug in the md driver that I was
experiencing.
Since using MAXPHYS is such an easy mistake to make, it is best to
hide it from the kernel namespace. So I've moved its definition to
_maxphys.h, which is now included in param.h only for userspace.
That brings up the fact that lots of userspace programs use MAXPHYS
for different reasons, most of them probably wrong. Userspace consumers
that really need to know the value of maxphys should probably be
changed to use the kern.maxphys sysctl. But that's outside the scope
of this change.

There are a few places in which unionfs_rename() accesses fvp's private
data without holding the necessary lock/interlock. Moreover, the
implementation completely fails to handle the case in which fdvp is not
the same as tdvp; in this case it simply fails to lock fdvp at all.
Finally, it locks fvp while potentially already holding tvp's lock, but
makes no attempt to deal with possible LOR there.
Fix this by optimistically using the vnode interlock to protect
the short accesses to fdvp and fvp private data, sequentially.
If a file copy or shadow directory creation is required to prepare
the upper FS for the rename operation, the interlock must be dropped
and fdvp/fvp locked as necessary.
Additionally, use ERELOOKUP (as suggested by kib@) to simplify the
locking logic and eliminate unionfs_relookup() calls for file-copy/
shadow-directory cases that require tdvp's lock to be dropped.
This check is not related to channel initializion, but is also
unnecessary, since sysctl_hw_snd_timeout() takes care of checking if
chn_timeout is within bounds.

The unit.* code is largely obsolete and imposes limits that are no
longer needed nowadays.
- Capping the maximum allowed soundcards in a given machine. By default,
the limit is 512 (snd_max_u() in unit.c), and the maximum possible is
2048 (SND_UNIT_UMAX in unit.h). It can also be tuned through the
hw.snd.maxunit loader(8) tunable. Even though these limits are large
enough that they should never cause problems, there is no need for
this limit to exist in the first place.
- Capping the available device/channel types. By default, this is 32
(snd_max_d() in unit.c). However, these types are pre-defined in
pcm/sound.h (see SND_DEV_*), so the cap is unnecessary when we know
that their number is constant.
- Capping the number of channels per-device. By default, the limit 1024
(snd_max_c() in unit.c). This is probably the most problematic of the
limits mentioned, because this limit can never be reached, as the
maximum is hard-capped at either hw.snd.maxautovchans (16 by default),
or SND_MAXHWCHAN and SND_MAXVCHANS.
These limtits are encoded in masks (see SND_U_MASK, SND_D_MASK,
SND_C_MASK in unit.h) and are used to construct a bitfield of the form
[dsp_unit, type, channel_unit] in snd_mkunit() which is assigned to
pcm_channel->unit.
This patch gets rid of everything unit.*-related and makes a slightly
different use of the "unit" field to only contain the channel unit
number. The channel type is stored in a new pcm_channel->type field, and
the DSP unit number need not be stored at all, since we can fetch it
from device_get_unit(pcm_channel->dev). This change has the effect that
we no longer need to impose caps on the number of soundcards,
device/channel types and per-device channels. As a result the code is
noticeably simplified and more readable.
Apart from the fact that the hw.snd.maxunit loader(8) tunable is also
retired as a side-effect of this patch, sound(4)'s behavior remains the
same.

sound: Fix panic caused by sleeping-channel destruction during asynchronous detach
Currently we are force-destroying all channels unconditionally in

possible as of 44e128fe9d92, if we do not check whether the channel is
sleeping or not and forcefully kill it, we will get a panic from
cv_timedwait_sig() (called from chn_sleep()), because it will try to use
a freed lock/cv.
Modify pcm_killchan() (renamed to pcm_killchans() since that's a more
appropriate name now) to loop through the channel list and destroy only
the channels that are awake, otherwise wake up the sleeping thread and
try again. This loop is repeated until all channels are awakened and
destroyed.
To reduce code duplication, implement chn_shutdown() which wakes up the
channel and sets CHN_F_DEAD, and use it in pcm_unregister() and
pcm_killchans().
