1. Add new functionality to the force_depend method to incorporate the
tests for whether the service is enabled and/or already running.
2. Add a new option to bypass checking only that the service is enabled
at boot time, and always check if it is running.
3. Use this new functionality to greatly simplify the rc.d scripts that
use force_depend.
4. Add a force_depend for statd in lockd
5. Remove the check that either nfs_server or nfs_client is _enable'd
from statd and lockd. This was always overkill, and prevented using
the {one|force}start options, as well as stop'ing on the command line.
6. The yp* scripts had some of their arguments in various weird orders.
Bring them into line with the model.
7. If mountd fails to create /var/db/mountdtab, err out.

MOD_SHUTDOWN is not an end of existence, and there is a life after it.
In particular, code previously called on MOD_SHUTDOWN grabbed lock and
deallocated unit numbering. That caused infinite wait loop if snd_uaudio
tried to destroy its PCM device after that point.

Note that besides currently there not being a quirk type that disables
MSI-X only and there's no evidence that MSI doesn't work with the VMware
pass-through, it's really questionable whether MSI generally works in
that setup as VMware only mention three know working devices [1, p. 4].
Also not that this quirk entry currently doesn't affect the devices
emulated by VMware in any way as these don't claim support MSI/MSI-X to
begin with. [2]
While at it, make the PCI quirk table const and static.

- add generic lock and irq handling routines. These can be useful
in case there are no driver locks that we can reuse;
- add a few macros to reduce differences with the Linux version.
Some older firmware versions have issues that can be worked around by
avoiding certain operations. Add a sysctl dev.aac.#.firmware_build to
make it easy for scripts or userland tools to detect the firmware

size of the structure;
* conf_cap is now a uint8_t rather than a uint16_t (uint16_t in D3.0,
uint8_t in the amendment spec);
* Update mesh config capability bits - earlier bits were from draft X,
current is amendment spec;
* Update the following to be an enum rather than #define and added
a VENDOR entry too from the amendment spec;

IEEE80211_MESHCONF_METRIC_*

IEEE80211_MESHCONF_SYNC_*
IEEE80211_MESHCONF_AUTH_*
* Kept IEEE80211_MESHCONF_FORM_* and IEEE80211_MESHCONF_CAP_* as

* In IEEE80211_MESHCONF_CAP_* IEEE80211_MESHCONF_CAP_TBTTA is removed

When performing a firmware upgrade via atacontrol[1] the subsequent
command may time out producing the error message above. When this
happens the callout could still be active, and the system would then
panic due to a destroyed semaphore.
Instead, ensure that the callout is done first, via callout_drain.
Note that this fix applies to the "old" ata(4) and so isn't applicable
to the default configuration in HEAD. It is still applicable to
stable/8.

There are unfortunately a number of situations where vap->iv_bss is changed
or freed by some code in net80211. Because multiple threads can concurrently
be doing work (and the vap->iv_bss access isn't at all done behind any kind
of lock), it's quite possible that:
* a change will occur in one thread - eg, by a call through
ieee80211_sta_join1();
* a state change occurs in another thread - eg an RX is scheduled
in the ath tasklet and it calls ieee80211_input_mimo_all(), which
does dereference vap->iv_bss;
* these two executing concurrently, causing things to explode.
Another instance is ath_beacon_alloc() which takes an ieee80211_node *.
It's called with the vap->iv_bss node from ath_newstate(). If the node has
changed in the meantime (say it's been freed elsewhere) the reference
that it grabbed _before_ refcounting it may be stale.
I would _prefer_ that these sorts of things were serialised somewhere but
that may be a bit much to ask. Instead, the best we can (currently) hope
is that the underlying bss node is still (somewhat) valid.
There is a related PR (kern/164382) described by the first case above.
That should be fixed by properly serialising the RX path and reset path
so an RX can't occur at the same time as the vap free/shutdown path.
This is inspired by some related fixes in r212127.

The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.
I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.

According to POSIX, -a is equal to -bdlprtTu. It seems this is not true
in practice, as -b normally restricts the output to BOOT_TIME entries
and all implementations that I know of don't.
This has the following advantages:
- During boot, the BOOT_TIME record is now written right after the file
systems become writable, but before users are allowed to log in. This
means that they can't cause `hidden logins' by logging in right before
init(8) kicks in.
- The pututxline(3) function may potentially block on file locking,
though this is very rare to occur. By placing it in an rc script, the
user can still kill it with ^C if needed.
- Most importantly: jails don't use init(8). This means that a force
reboot of a system running jails will leave stale entries in the
accounting database of the jails individually.
Ignore the NAT_T extension types so we can at least dump the SADB from
the in-base libipsec/setkey without error when NAT_T support is present
in the kernel, though not printing the additional information yet.
However in case there is no NAT_T support in kernel still consider them
to be an error.

At first, I added a utility called utxrm(8) to remove stale entries from
the user accounting database. It seems there are cases in which we need
to perform different operations on the database as well. Simply rename
utxrm(8) to utx(8) and place the old code under the "rm" command.
In addition to "rm", this tool supports "boot" and "shutdown", which are
going to be used by an rc-script which I am going to commit separately.
