lockf: Avoid spinning when operating on an fd
When operating on a file descriptor, acquire_lock() would ignore the
flags argument and always operate in non-blocking mode, resulting in
unnecessary busy-looping.

Add PCI device IDs for two Ice Lake PCH SMBus controller variants:
- 0x34a3 (Ice Lake-LP), previously listed as the generic "Ice Lake" entry (ID_ICELAKE), renamed to ID_ICELAKELP for clarity.
- 0x38a3 (Ice Lake-N), a separate PCH variant not previously supported.

certctl: Unstickify (un)trusted certificates
Ever since certctl was rewritten in C, the rehash command has reingested
TRUSTDESTDIR / UNTRUSTDESTDIR in addition to TRUSTPATH / UNTRUSTPATH.
This seemed like a good idea at the time but was, in retrospect, a
mistake, as it means a (un)trusted certificate remains (un)trusted
forever (or at least until it expires) even if it is removed from
(UN)TRUSTPATH. Among other issues, it causes ports QA to fail for any
port that either installs certificates or depends on a port that does.
Although this behavior was undocumented, the change may surprise users
who have added certificates manually, so update the manual page to point
it out and add prominent warnings to the trust and untrust commands.

pf: do not reject rules with colliding hashes
We insert rules in pf_krule_global solely for the benefit of the
'keepcounters' feature. Failing to insert (beause the rule hash
collides, or an identical rule already exists) would be worse than
restoring counts to the wrong rule (or failing to restore them at all).

acpi_panasonic: acquire serial lock before calling hkey_sound_mute in shutdown
acpi_panasonic_shutdown() calls hkey_sound_mute() without holding
the ACPI serial lock. Every other call site holds
`ACPI_SERIAL_BEGIN(panasonic)` before calling it, as the locking
model is caller-owned.
This seems to affect the whole Panasonic Toughtbook lineup btw.

mii: Fix SMSC name
The LAN8700 / LAN8710 PHYs were Standard Microsystems Corporation (SMSC)
parts. I presume SMC was chosen as an abbreviation, but the company
always used SMSC as its short name.
SMSC was acquired by Microchip in 2012. I kept the pre-acquisition
name, as NetBSD (from where we obtained miidevs) uses SMSC.

libusb: change callback register handler to int
libusb upstream uses int for register handler. This causes some library
user (like pyusb) to assume that we have int in all implementations and
therefore provides a 4 byte storage only. This causes Segmentation
fault as we will right the pointer.

pf: improve ASCONF chunk validation
When processing an ASCONF chunk we failed to verify that the chunk
length was at least 8 bytes. As a result we might end up passing a
negative length to pf_multihome_scan(). Fortunately this merely meant
the function did nothing, but we should discard such invalid packets, so
explicitly check for this.
