The kernel was already doing this prior to r329615. It was changed
to reduce contention on allproc. However, introduction of pidhash
locks and removal of proctree -> allproc ordering from fork thanks
to bitmaps fixed things enough to make this change pessimal.
waitpid takes proctree on each call and this change (now) causes
avoidable stalls if allproc is held.

Currently unique pid allocation on fork often requires a full walk of
process, group, session lists to make sure it is not used by anything.
This has a side effect of requiring proctree to be held along with allproc,
which adds more contention in poudriere -j 128.
The patch below implements trivial bitmaps which gets rid of the problem.
Dedicated lock is introduced to manage IDs.
While here a bug was discovered: all processes would inherit reap id from
the first process spawned by init. This had a side effect of keeping the
ID used and when allocation rolls over to the beginning it keeps being
skipped.
The patch is loosely based on initial work by mjoras@.

The current ifdefs are not sufficient to distinguish 32- and 64- bit
variants, which results e.g. in powerpc64 not using atomics.
While some 32-bit archs provide 64-bit atomics, there is no huge advantage
of using them on these platforms.

The iflib subsystem implements netmap support in a driver-independent
way (sys/net/iflib.c). We can therefore remove the headers that
used to implement netmap support for all the drivers now supported
by iflib (em, igb, ixl, ixgbe, lem).

The sender has .not_terminated file. It gets disconnected. The last trail
file is then terminated without adding new data (this can happen for example
when auditd is being stopped on the sender). After reconnect the .not_terminated
was not renamed on the receiver as it should.
We were already handling similar situation where the sender crashed and the
.not_terminated trail file was renamed to .crash_recovery. Extend this case to
handle the situation above.
Re-apply r341665 with format strings fixed.
If we happen to taste a stale mirror component first, don't reject valid,
newer components that have differing metadata from the stale component
(during STARTING). Instead, update our view of the most recent metadata as
we taste components.
Like mediasize beforehand, remove some checks from g_mirror_check_metadata
which would evict valid components due to metadata that can change over a
mirror's lifetime. g_mirror_check_metadata is invoked long before we check
genid/syncid and decide which component(s) are newest and whether or not we
have quorum.
Before checking if we can enter RUNNING (i.e., we have quorum) after a NEW
component is added, first remove any known stale or inconsistent disks from
the mirrorset, rather than removing them *after* deciding we have quorum.
Check if we have quorum after removing these components.
Additionally, add a knob, kern.geom.mirror.launch_mirror_before_timeout, to
force gmirrors to wait out the full timeout (kern.geom.mirror.timeout)
before transitioning from STARTING to RUNNING. This is a kludge to help
ensure all eligible, boot-time available mirror components are tasted before
RUNNING a gmirror.
Add a basic test case for STARTING -> RUNNING startup behavior around stale
genids.

r341392 changed common test cleanup routines in a way that allowed them to
be used by TAP tests as well as ATF tests. However, a late change made
during code review resulted in cleanup being broken for ATF tests, which
source geom_subr.sh separately during the body and cleanup phases of the
test. The result was that md(4) devices wouldn't get cleaned up.

pfsync code is called for every new state, state update and state
deletion in pf. While pf itself can operate on multiple states at the
same time (on different cores, assuming the states hash to a different
hashrow), pfsync only had a single lock.
This greatly reduced throughput on multicore systems.
Address this by splitting the pfsync queues into buckets, based on the
state id. This ensures that updates for a given connection always end up
in the same bucket, which allows pfsync to still collapse multiple
updates into one, while allowing multiple cores to proceed at the same
time.
The number of buckets is tunable, but defaults to 2 x number of cpus.
Benchmarking has shown improvement, depending on hardware and setup, from ~30%
to ~100%.
