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.

Push kernel lock inside ifioctl_get()
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.

amd64: switch to clockintr(9)
Switch amd64 to the clockintr(9) subsystem. There are lots of little
changes, but the bigs ones are listed here.
When using the local apic timer:
- Run the timer in one-shot mode.
- lapic_delay() is gone. We can't use it to delay(9) when running
the timer in one-shot mode.
- Add a randomized statclock(); stathz = hz.
- Add support for switching to profhz when profiling is enabled;
profhz = stathz * 10.
When using the i8254/mc146818:
- i8254's clockintr() no longer has a monopoly on hardclock().
- mc146818's rtcintr() no longer has a monopoly on statclock().
- In profiling mode, the statclock() will drift very slightly
because (profhz = 1024) does not divide evenly into one billion.
We could avoid this by setting (profhz = 512) instead and
programming the RTC to run at that rate.
Early revisions reviewed by mlarkin@. Extensively tested by mlarkin@
on a variety of physical and virtual hardware. Additional testing
from dv@ and jmc@.

Refactor/split ED25519_keypair.
This brings in ED25519_keypair_from_seed() from BoringSSL commit
c034e2d3ce16, which ED25519_keypair then wraps. This reduces differences
between us and BoringSSL.
