vendor provided pmu-events tables and sundry cleanups.
The vendor pmu-events tables provide counter descriptions, default
sample rates, event, umask, and flag values for all the counter
configuration permutations. Using this gives us:
- much simpler kernel code for the MD component
- helpful long and short event descriptions
- simpler user code
- sample rates that won't overload the system
Update man page with newer sample types and remove unused sample type.

pmu-events: expand out skylake regex to simplify string matches
r307825 and r333017 disallow building FreeBSD-HEAD from 9.x or 10.x
versions that have some clang issues. The minimum supported Subversion
revisions and osreldates containing the fix are:
Version Min Rev osreldate
9.x r286035 903509
10.x r286033 1002501
9.3 is the final 9.x release and does not contain the r286035 fix.
10.3 is the first 10.x release with the fix. Thus, in practice 10.3 is
the oldest release that can build HEAD.
Although it may still be possible to build HEAD from an up-to-date
stable/9 it's not worth maintaining the special case when the branch
itself is unsupported and there are no usable releases from that branch.
Old UPDATING entries can be removed and the Clang warning in UPDATING
may be updated, in a future commit.

kernel.ucl uses a hardcoded boot/kernel for kldxref, which is the incorrect
directory when we're installing extra kernels that aren't the "default"
kernel (placed at boot/kernel).
Fix this by instead using a new %KERNELDIR% that we now replace in
Makefile.inc1 with "kernel" for the default kernel and "kernel.${_kernel}"
for these extra kernels so that, e.g. /boot/kernel.SHIVA, will get properly
kldxref'd upon update and avoid outdated linker.hints.

This code, which is basically `svnversion || svnliteversion`, generates

includes bsd.own.mk. This can add up for things like generating a Ports

A comment in Makefile.inc1 has long stated that LOCAL_DIRS are built last,
after the base system. Incremental improvements in parallel building over
the years have led to LOCAL_DIRS being built in parallel with base system
directories. This change allows the .WAIT directive to appear in LOCAL_DIRS
and LOCAL_LIB_DIRS lists to give the user some control over parallel
building of local additions.

Because we force enable MK_GCC when building we need to also force
enable it for the cleaning phase. Otherwise the NXB_TARGET files
are found in the next build's kernel-toolchain phase and cause
an error.

The initial kernel-toolchain is built with TARGET=MACHINE but
we want GCC to have files generated for TARGET=NXB_TARGET
instead later on. Just clean the files between building of
the toolchain and nxb binaries which will let it rebuild
when needed.

Packaged base packages are created by running the stageworld and
stagekernel targets with -DNO_ROOT, and converting the resulting mtree
file into a set of pkg plists. If stage* is run with multiple processes
the order of entries in the mtree file may be nondeterministic, and the
resulting package tbz also had nondeterministic file ordering.
The mtree file generated by -DNO_ROOT builds consists of one line per
file, with the filename starting in the first column, so is easily
sorted. There's one exception: the first line of the mtree file is a
comment, but the # character sorts before the filenames anyhow and needs
no special treatment.

- This also adds in a _cleanobj step as needed.
- This redirects TARGET/TARGET_ARCH to NXB_TARGET/NXB_TARGET_ARCH in
Makefile.inc1 as the main build needs to be for MACHINE rather
than TARGET.
First build the toolchain and then use that as an external toolchain
to build the needed directories and NXB_TARGET-toolchain, all as
MACHINE files though via TARGET_TRIPLE=MACHINE_TRIPLE.
The NXBDIRS is evaluated in the 'everything' submake as it needs to be
based on TARGET's src.opts.mk values, such as MK_GCC=yes when building
on a MK_CLANG=yes MACHINE. This can likely be changed to a specific
_native-xtools-everything target later and the funky late evaluation
of SUBDIR_OVERRIDE removed.

- If OBJROOT is SRCTOP then don't add on TARGET.TARGET_ARCH. This
only happens at the top-level, and for sub-directories when the
user is clever with MAKEOBJDIRPREFIX=/.
- Don't bother checking 'test -w' on .CURDIR.
- Properly set OBJTOP/OBJROOT to SRCTOP in various needed cases.
- Check if the OBJDIR is writable even for *clean* targets since it
determines which .OBJDIR the user gets; If they cannot write to an
existing eligible .OBJDIR then it needs to clean in .CURDIR instead.
- Add guard to cleanworld/cleanuniverse from removing SRCTOP.
- Ensure OBJTOP is proper for .OBJDIR=.CURDIR which fixes finding
libraries since src.libnames.mk is based on OBJTOP.
- Avoid some chdir(2) for modifying .OBJDIR
