ifnet: Fix decreasing the vnet interface count
It should be decreased only when the interface has been successfully
removed from the "active" list.
This prevents vnet_if_return() from potential OOB writes to the
allocated memory "pending".

timerfd: Suppress kqueue readability after jump read
Do not report EVFILT_READ after reading a discontinuous clock jump.
This makes the kqueue filter consistent with Linux epoll behavior
and timerfd_poll(), which already checks tfd_jumped != TFD_READ before
reporting POLLIN.

timerfd: Wake up on discontinuous jump
If a discontinous realtime clock change occurs and sets any TFD_JUMPED
bits on the timerfd, then wake up waiting readers. This fixes failures
from the timerfd_root__clock_change_notification test case.

sys/time: Add saturating sbt conversions
When converting from timespec to sbintime, the timespec's 64-bit tv_sec
component is shifted to the left 32 bits, causing any information in the
upper 32 bits to be lost.
This data loss during conversion can turn timespecs with very large
tv_sec counters into sbintimes that represent much smaller time
durations.
Add tstosbt_sat() and tvtosbt_sat(), which are saturating versions of
tstosbt and tvtosbt. With these routines, any overflow resulting from
the conversion is clamped to [-SBT_MAX - 1, SBT_MAX].

timerfd: Add tests
Take Jan Kokemuller's timerfd tests from the epoll-shim project,

timerfd: Use saturating sbintime conversions
Some timerfd consumers set expirations with timespec tv_sec components
larger than 2^31 - 1. In such cases, converting that timespec to
sbintime results in data loss or sign flip, yielding a shorter
expiration than desired.
To avoid this problem, use saturating timespec-to-sbintime conversion
functions. These will clamp the converted sbintime to SBT_MAX under
circumstances where the normal conversion functions would overflow.
Saturating conversions still result in data loss, but the consequences
are less severe, causing problems only after SBT_MAX (~68 years) of
system uptime elapses.

timerfd: Fix interval callout scheduling
When a timerfd interval callout misses its scheduled activation time, a
differential is calculated based on the actual activation time and the
scheduled activation time. This differential is divided by the timerfd's
interval time and the quotient is added to the timerfd's counter.
Before this change, the next callout was scheduled to activate at:
scheduled activation time + timerfd interval.
This change fixes the scheduling of the next callout to activate at:
actual activation time + timerfd interval - remainder.

libcrypto: compile all PIC objects with -DOPENSSL_PIC
This change modifies the libcrypto PIC objects to always compile with
`-DOPENSSL_PIC` to restore parity with the upstream build process. This
ensures that `-DOPENSSL_PIC` is used whenever building the auxiliary
shared objects. In this case, just the legacy provider (we no longer
distribute the fips provider).

ath11k: restore module Makefile
During the subtree merge and checking out the updated version of ath12k
parts of the previous ath11k merge were accidentally undone.
Retore the ath11k Makefile as well after 3c4eef5d838b restored the
driver bits.

ath11k: reduce diff to upstream Atheros/QCA's ath11k driver
It seems that over the time of merging and only partly working
on making it compile again a few mis-merges happened.
Reduce diff to the v6.19 upstream version so that we only have
additions to the driver (usually guarded by #ifdef __FreeBSD__).
