This fixes when an IP address mapping is put in the hostmap table for
sticky NAT rules, it ends up having the wrong byte order.

Callers of zone_drain_wait(M_WAITOK) do not need to hold (and were not)
the uma_mtx, but we would attempt to unlock and relock the mutex if we
had to sleep because the zone was already draining. The M_NOWAIT callers
may hold the uma_mtx, but we do not sleep in that case.

LOR of softc rmlock in iflladdr_event handlers.
- Call if_delmulti_ifma() after LACP_UNLOCK(). This fixes another LOR.
- Fix a panic in lacp_transit_expire().
- Fix a panic in lagg_input() upon shutting down a port.
When the screen size is unknown, it's set to 0x0. We can't use that as
the buffer size, otherwise, functions such as vtbuf_fill() will fail.
This fixes a panic on RaspberryPi, where there's no vt(4) backend
configured early in boot.

- Do not dump into system files.
- Do not acquire write reference to the mount point where img.core is
written, in the coredump(). The vn_rdwr() calls from ELF imgact
request the write ref from vn_rdwr(). Recursive acqusition of the
write ref deadlocks with the unmount.
- Instead, take the range lock for the whole core file. This prevents
parallel dumping from two processes executing the same image,
converting the useless interleaved dump into sequential dumping,
with second core overwriting the first.

callout is now scheduled using the C_ABSOLUTE flag, and the absolute time
of each event is calculated as the time the previous event was scheduled
for plus the interval. This ensures that latency in processing a given
event doesn't perturb the arrival time of any subsequent events.

This could result either in protection bypass or in a spurious ENOTCAPABLE.

modifications to libproc to support fetching the CTF info for a given file.
With this change, dtrace(1) is able to resolve type info for function and
USDT probe arguments, and function return values. In particular, the args[n]
syntax should now work for referencing arguments of userland probes,
provided that the requisite CTF info is available.
The uctf tests pass if the test programs are compiled with CTF info. The
current infrastructure around the DTrace test suite doesn't support this
yet.
