libexec/rc: Add var_run rc script
Users with a tmpfs /var/run will lose the directory tree state of
/var/run at reboot. This rc script will optionally (by default)
capture the state of the directory structure in /var/run prior to
shutdown and recreate it at system boot.
Alternatively a user can save the state of the /var/run directories
manually using service var_run save and disable the autosaving of
/var/run state using the var_run_autosave variable, for those
paranoid SSD users.
It is only there to check if the packet was reassembled,
relevant if we are forwarding. But if the packet originated
locally it could not have been reassembled, thus the flag is
redundant.

nfscl: Allow "nolockd" to work for NFSv4 mounts
Commit 40ada74ee1da modified the NFSv4.1/4.2 client so
that it would issue a DestroySession to the server when
all session slots are marked bad. This handles the
case where session slots get broken when "intr" or "soft"
NFSv4 fairly well.1/4.2 mounts are done.
There are two other cases where having an NFSv4.1/4.2
RPC attempt terminate without completion can leave
state in a non-determinate condition.
One is file locking RPCs. If the "nolockd" option is
used, this avoids file locking RPCs by doing locking
locally within the client.
The other is Open locks, but since all FreeBSD Open
locks are done with OPEN_SHARE_DENY_NONE, the locking
state for these should not be critical.
This patch enables use of "nolockd" for NFSv4 mounts,
so that it can be combined with "intr" and/or "soft",
making the latter more usable.
Use of "intr" or "soft" NFSv4 mounts are still not
recommended, but when combined with "nolockd" should
now work fairly well.
A man page update will be done as a separate commit.

stand/kboot: Add note about why we use MACHINE_ARCH here
Normally in the boot loader, we key off of MACHINE since that specifies
the kernel and the loader is very tuned to each type of MACHINE in
general. In this case, however, we're producing a Linux binary, with
Linux system calls encoded in it. These align better along the
MACHINE_ARCH axis of FreeBSD. For PowerPC the system calls are radically
different for each of our MACHINE_ARCHes, with only powerpc64 and
powerpc64le sharing the same numbers and memory layout. The same was
true about mips when it was in the tree. 32-bit arm uses the same
layout, however, for both armv6 and armv7 ports: that can be easily
shared in the unlikely event we support that in the future.
Rtld locks from libthr defer signals delivery, which means that binding
is not possible while a signal handler is executed.
Binding might upgrade read-locked rtld_bind_lock to write-lock, if
symbol resolution requires loading filters. If a signal would be delivered
while rtld is in read-locked section, and signal handler needs binding
which upgrades the lock, for non-threaded image that uses default rtld
locks, we get the rtld data structures modified under the top-level
active rtld frame.
To correct the problem, mask signals for read-locking of default locks
in addition to the write-locking. It is very cheap now with
sigfastblock(2).
Note that the global state is used to track pre-locked state of either
sigfastblock(2) or signal mask (if sigfastblock(2) is administratively
disabled). It is fine for non-threaded images since there are no other
threads. But I believe that it is fine for threaded images using libc_r
as well, since masking signals disables preemption (I did not tested
it).
For consistency rename LKPI_SCAN_RUNNING adding a LHW_ prefix.
Add a local flag LKPI_LHW_SCAN_HW mirroring the net80211
IEEE80211_FEXT_SCAN_OFFLOAD flag.
Slightly simplify the code.
Overload (*ic_scan_curchan) and (*ic_scan_mindwell) so that we can
call the net80211 implementation in case of software scan but skip it
in case of full-offload scans.
Also add a bandaid to our (*ic_set_channel) implementation to not siwtch
channels if we have an active hw_scan running.

Implement the mac80211 (*get_antenna) call and after checking any

Both the wiphy variables and function call report a bitmask not a count.

As the function itself seems to be helpful don't remove the code but
change the #ifdef DEBUG to #if 0 to avoid:
warning: unused function 'mgb_dump_some_stats' [-Wunused-function]
with LINT builds.
Properly handle the replacement of a partially allocated root directory.
If the root directory exists but has a bad block number Pass1 will
accept it and setup an inoinfo structure for it. When Pass2 runs
and cannot read the root inode's content because of a bad (or
duplicate) block number, it removes the bad root inode and replaces
it. As part of creating the replacement root inode, it creates an
inoinfo entry for it. But Pass2 did delete the inoinfo entry that
Pass1 had set up for the root inode so ended up with two inoinfo
structures for it. The final step of Pass2 checks that all the ".."
entries are correct adding them if they are missing which resulted
in a second ".." entry being added to the root directory which
definitely did not go over well in the kernel name cache!

* Forms refactoring. Complete rewrite deleting libformw dependency.
* Theme. New utility options to save and load custom theme at run-time.
* TUI navigation. Added keys to navigate input components. Changed
default focus behavior of input dialogs to be LGPL-dialog-like; a new
