syscalls.master: Allow clock_nanosleep in capability mode

It is akin to nanosleep(2) and does not access global namespaces.
It should be permitted in capability mode.

if_media: Claim 10BASE-T1S and 10BASE-T1L constants

These are two single-pair Ethernet (SPE) variants that run at 10 Mbps.
10BASE-T1S has automotive origins and supports multiple nodes on up to
25m of cable.  10BASE-T1L is intended for building and industrial
automation and supports long-distance point to point links of over 1km.

[llvm][GVNSink] Avoid non-determistic iteration order over NeededPHIs (#205952)

The iteration order of DenseSet is not guaranteed, which affects the
output of code generated with GVNSink enabled. This can cause code to be
emitted in differing order, affect section ordering, and in some cases
was reported to result in larger binaries due to increased padding between
sections.

This patch addresses this by using SetVector, which has a deterministic
iteration order.

acpi_timer(4): Remove unused 'acpi_timer_disabled' boolean

Same reason as for the previous commit to acpi_cpu(4).  This boolean is
not used anywhere.  Disabling acpi_timer(4) can be done through the
regular ACPI disable mechanism (using the 'debug.acpi.disabled' tunable,
see acpi_disabled()).

tests/pf/route_to: check_random: rely on test timeout to fail

This test is known to be flaky if 10 attempts happens to be
not enough for the test to pass. Usually, this test passes in ~4-6 attempts.
See https://ci.freebsd.org/job/FreeBSD-main-amd64-test/28664/testReport/junit/sys.netpfil.pf/route_to/random_table/

Rely on the timeout (default 5 mins) to catch a failure here, rather than just 10
attempts. It's very unlikely that 5 mins worth of attempts still isn't enough.

For a history of flakiness, see
