help catch such potential failures.

e.g. boot_mute, boot_single, boot_verbose, and friends; we checked for these
in multiple places, consolidate into common/ and allow a setting of "NO" for
any of these to turn them off. This allows systems with multiple
loader.conf(5) or loader.conf(5) overlay systems to easily turn off
variables in later processed files by setting it to NO.

If a locally generated packet is routed (with route-to/reply-to/dup-to) out of
a different interface it's passed through the firewall again. This meant we
lost the inp pointer and if we required the pointer (e.g. for user ID matching)
we'd deadlock trying to acquire an inp lock we've already got.
Pass the inp pointer along with pf_route()/pf_route6().

Since we are setting IFF_UP flag on SIOCSIFADDR, it is possible, that
after this link state information still not initialized properly.
This leads to problems with routing, since now interface has
IFCAP_LINKSTATE capability and a route is considered as working only
when interface's link state is in LINK_STATE_UP (see RT_LINK_IS_UP()
macro).

Per-cpu zone allocations are very rarely done compared to regular zones.
The intent is to avoid pessimizing the latter case with per-cpu specific
code.
In particular contrary to the claim in r334824, M_ZERO is sometimes being
used for such zones. But the zeroing method is completely different and
braching on it in the fast path for regular zones is a waste of time.

If we fail noise floor calibration then we may end up with a deaf NIC
which we can't recover without a full chip reset.
Earlier chips seem to get less stuck in this condition versus AR9280/later
and AR9300/later, but whilst here just fix up the AR5212 era chips to also
return NF calibration failures.
This HAL routine would only return failure if the channel was not configured.
This is a no-op until the driver side code for doing resets and the HAL
code for being told about the reset type (and then handling it!) is
implemented.
Tested:
* AR9280, STA mode
* AR2425, STA mode
* AR9380, STA mode

During scans (scrubs or resilvers), it sorts the blocks in each transaction
group by block offset; the result can be a significant improvement. (On my
test system just now, which I put some effort to introduce fragmentation into
the pool since I set it up yesterday, a scrub went from 1h2m to 33.5m with the
changes.) I've seen similar rations on production systems.

Turns out there is code which ends up passing M_ZERO to counters.
Since counters zero unconditionally on their own, just ignore drop the
flag in that place.
pmc_process_interrupt takes 5 arguments when only 3 are needed.
cpu is always available in curcpu and inuserspace can always be
derived from the passed trapframe.
While facially a reasonable cleanup this change was motivated
by the need to workaround a compiler bug.
core2_intr(cpu, tf) ->
pmc_process_interrupt(cpu, ring, pmc, tf, inuserspace) ->
pmc_add_sample(cpu, ring, pm, tf, inuserspace)
In the process of optimizing the tail call the tf pointer was getting
clobbered:

1205 error = pmc_process_interrupt(cpu, PMC_HR, pm, tf,
resulting in a crash in pmc_save_kernel_callchain.
Nothing in the tree uses it and pcpu zones have a fundamentally different use
case than the regular zones - they are not supposed to be allocated and freed
all the time.
This reduces pollution in the allocation fast path.
(or peel off the band-aid, whatever floats your boat)
This addresses two separate issues:
1.) Nothing within bsdgrep actually knew whether it cared about line numbers
or not.
2.) The file layer knew nothing about the context in which it was being
called.
#1 is only important when we're *not* processing line-by-line. #2 is
debatably a good idea; the parsing context is only handy because that's
where we store current offset information and, as of this commit, whether or
not it needs to be line-aware.
