ip_mroute: Fix a lock leak in X_ip_mforward()
If a FIB does not have a router configured, X_ip_mforward() would leak a
lock. Plug the leak.
The IPv6 counterpart did not have such a check. It wouldn't send an
upcall to a non-existent router anyway due to the router_ver check, but
we should verify that a router is present anyway.
Add regression test cases to exercise these code paths.

thunderbolt: Support generic USB4 NHIs

USB4 NHIs are supported anyway, and all remnants of ICM-supporting code
are removed too. All devices now use the HCM.

rc.d/NETWORKING: remove the NETWORK alias
NETWORKING is the documented placeholder, while
/etc/rc.d/NETWORKING still provides the legacy alias
NETWORK.
The NETWORKING script was originally introduced to avoid
conflicts with NetBSD's lowercase network script on
case-insensitive file systems. The NETWORK alias was
retained for compatibility with older scripts.
Following the discussion in PR 293652, remove the legacy
NETWORK alias from 16-CURRENT. Keeping both names adds
more confusion than value now that NETWORKING is the
documented placeholder and current base system and ports
tree uses are already clean.
Add an UPDATING entry to note that local RC scripts using
REQUIRE: NETWORK should be migrated to REQUIRE: NETWORKING.

sys/time: appease gcc -Wtype-limits
In environments where time_t is 32 bits, including the 32-bit library
build on amd64, the overflow being tested for cannot happen, and gcc
complains with -Wtype-limits, causing the gcc build to fail. Work
around this by ifdef'ing out the saturation code on i386.

stat: Nits in stat tests
* Use ourselves as test file instead of /COPYRIGHT, which may or may not
be present in the test environment.
* atf-check understands \n in strings, use it.
* Some file systems don't like creating small holes, so create large ones
instead. This means we need two variables: ps (page size) is the
minimum size of a data region and the alignment for a hole, while hs
(hole size) is the minimum size of the holes we create. This makes no
difference on FreeBSD but makes it easier to port the test to other
platforms.

asmc: add raw SMC key read/write interface
This patch adds a debugging interface to read and write arbitrary
Apple SMC keys by name through sysctl, enabling hardware exploration
and control of undocumented features.
The interface provides four sysctls under dev.asmc.0.raw.*:
- key - Set the 4-character SMC key name (e.g., "AUPO")
- value - Read/write key value as a hex string
- len - Auto-detected key value length (can be overridden)
- type - Read-only 4-character type string (e.g., "ui8", "flt")
Implementation includes a new asmc_key_getinfo() function using SMC
command 0x13 to query key metadata. The interface automatically
detects key lengths and types, uses hex string encoding for
arbitrary binary values, and is safe for concurrent access via
CTLFLAG_NEEDGIANT.
This interface was essential for discovering that the AUPO key
