Long objdir paths make it easy to hit the version string length limit in
kernel dump headers. The build number and timestamp are unlikely to be
truncated and ought to be sufficient to protect against false positives.

The usual case of a mismatched checksum for installer snapshots
(e.g., -CURRENT, -ALPHA*) is that a newer snapshot has been built and
the old install sets have been replaced. Provide a specific error
message for checksum mismatches there that suggests looking for a newer
snapshot.

This patch modifies the nfsuserd daemon so that it uses an AF_LOCAL socket
for upcalls by default. This should fix the problem with using a UDP
socket upcall to 127.0.0.1 when jails are used.
The AF_LOCAL socket case only supports a single server daemon, since hangs
were observed by the original problem reporter when multiple daemons
were used.
The patch adds a command line option called "-use-udpsock" which makes
the daemon revert to its prepatched behaviour.

After the addition of SUBDIR.yes, uniquifying/ordering the SUBDIRs doesn't
make a whole lot of sense, and it's in effect a half measure.
Ordering SUBDIR (after adding SUBDIR.yes to it) in bsd.subdir.mk is a
separate change that warrants more discussion/testing, because while
the SUBDIR_PARALLEL work largely fixed dependency ordering for SUBDIRs,
there might be downstream FreeBSD consumers that rely on the SUBDIR
ordering.

ZFS SLOGs have very specific access pattern with many cache flushes,
which none of benchmarks I know can simulate. Since SSD vendors rarely
specify cache flush time, this measurement can be useful to explain why
some ZFS pools are slower then expected. This test writes data chunks
of different size followed by cache flush, alike to what ZFS SLOG does,
and measures average time.
To illustrate, here is result for 6 years old SATA Intel 710 Series SSD:

While the first one obviously has maximal throughput limitations, the
second one has so high cache flush latency (about 2 millisecond), that
it makes one almost useless in SLOG role, despite of its good throughput
numbers. Power loss protection is out of scope of this test, but I
suspect it can be related.

The reason is that FreeBSD refcount.h shadows ZFS refcount.h and that
will lead to a build error after a planned import of the ARC buf data
scatter-ization.
It's possible that some day we will have an opposite problem where
a ZFS header would shadow an essential FreeBSD header.
So, we need to think about a better long term solution.
