tc_setclock: don't print a warning if tc_windup() rejects inittodr(9) time
During resume, it isn't necessarily a problem if the UTC time we get
from inittodr(9) lags behind the system UTC clock. In particular, if
the active timecounter's frequency is low enough, tc_delta() might not
overflow across a brief suspend.
Remove the misleading warning message. The code is behaving as
intended, just not in a way I anticipated when I added the warning
message a few years ago.
Discovered by kettenis@. Root cause isolated with kettenis@.

vmm(4): remove locking in vmm_intr_pending
Removes a lock around an atomic write; this lock was causing slowdowns
since the lock being requested is nearly always unavailable because it
is held while the VM is running.
Noticed by claudio@, help from mpi@, dlg@ and claudio@.

Unlock SIOCIFGCLONERS
ifconfig(8) -C is the only user in base and the if_clone_attach() comment
explains how this list is being built during autoconf(9).
After that it is only ever read. Multiple threads may traverse the list in
parallel and reading the `int' count is atomic.

After this mechanical move, I can unlock the individual SIOCG* in there.

arm64: switch to clockintr(9)
Switch arm64 to the clockintr(9) subsystem.
- Remove the custom per-CPU clock interrupt schedule from agtimer(4).
- Remove the custom randomized statclock() pieces from agtimer(4).
- Add agtimer_rearm(), agtimer_trigger(), and wire up agtimer_intrclock.
There is one wart:
- The AArch64 spec says that a value written to CNTV_TVAL_EL0 is
"treated as a signed 32-bit integer" [1]. kettenis@ doesn't know
what to make of this. I'm capping the value at INT32_MAX for
now. It's possible I am misreading this, though.
Tested by kettenis@ on his Apple M1 mini. Tested by me on my
Raspberry Pi 4B.
