For use with things like BOOT_TAG=\"\" -- there are valid reasons to allow
empty strings, especially as these are usually being passed through as
options. The same argument could perhaps be made for the unquoted
variant in things like MODULES_OVERRIDE="", but it's not immediately clear
that this is an issue so I've left it untouched.

reassembly inbound tcp segments. The old algorithm just blindly
dropped in segments without coalescing. This meant that every
segment could take up greater and greater room on the linked list
of segments. This of course is now subject to a tighter limit (100)
of segments which in a high BDP situation will cause us to be a
lot more in-efficent as we drop segments beyond 100 entries that
we receive. What this restructure does is cause the reassembly
buffer to coalesce segments putting an emphasis on the two
common cases (which avoid walking the list of segments) i.e.
where we add to the back of the queue of segments and where we
add to the front. We also have the reassembly buffer supporting
a couple of debug options (black box logging as well as counters
for code coverage). These are compiled out by default but can
be added by uncommenting the defines.

This has two advantages:
1) We no longer create lots of empty directories that are not needed
2) This is a requirement for building on non-FreeBSD hosts since mtree will
only exist after the bootstrap-tools phase there.

This can cause surprising errors if the build tools is built against
headers that don't match the host system. It is also required in order
to allow building on non-FreeBSD systems where the headers in
/usr/include/sys are usually completely incompatible with those in the
source tree.
I added an error to Makefile.boot if this is done and found this was
only the case in libnv. With this error in the Makefile ABI breakages
such as r336019 should no longer be possible.

Now that a complete set is written, save for one describing loader.lua,
install all of them. This was not previously done as they were written to
hopefully avoid confusion as bits and pieces of the overall system were
undocumented.
This will only work if the caller already handles SIGSYS, which is not
always the case.
Address this by checking osreldate instead. Note that because there
was not __FreeBSD_version bump when the system call was added, use
1200061 (r332100) which is the first bump after the introduction of
the system call.

Recent DTS use the syscon for the emac controller.
We support this but since U-Boot is still using old DTS it was never
needed for us to add this support, but this is a problem when using upstream
recent DTS and will be when U-Boot will catch up.
While here add a new compatible to the aw_syscon driver as Linux changed it ...
Current mitigation for L1TF in bhyve flushes L1D either by an explicit
WRMSR command, or by software reading enough uninteresting data to
fully populate all lines of L1D. If NMI occurs after either of
methods is completed, but before VM entry, L1D becomes polluted with
the cache lines touched by NMI handlers. There is no interesting data
which NMI accesses, but something sensitive might be co-located on the
same cache line, and then L1TF exposes that to a rogue guest.
Use VM entry MSR load list to ensure atomicity of L1D cache and VM
entry if updated microcode was loaded. If only software flush method
is available, try to help the bhyve sw flusher by also flushing L1D on
NMI exit to kernel mode.

Uncovered while writing the documentation from this, we previously
explicitly fell back to orb or orbbw if an invalid or incompatible logodef
was selected -- in contrast to branddefs, which have an exported variable
that one can whip up a quick local.lua to override in a safe manner that
works regardless of whether or not loader.conf(5) successfully loads.
These are less controversial than the others, thus done in a separate
commit. These are all used internally and ways to override are provided via
soon-to-be-documented API or loader.conf(5) variables.
Ideally, all of the functionality to revamp the loader screen has associated
APIs that are flexible enough that third-party scripts wouldn't need to
override these.
Turns out there was a hidden dependency we hasn't counted upon. The
host load /boot/userboot.so to boot the VMs it runs. This means that
the change to lua meant suddently that nobody could run their older
VMs because LUA wasn't in 10.0, last month's HardenedBSD, 11.2 or
whatever. Even more than for the /boot/loader* binaries, we need a
good coexistance strategy for this. While that's being designed and
implemented, drop back to always 4th for userboot.so. This will fail
safe in all but the most extreme environments (but lua-only hacks
to .lua files won't be processes in VMs until we fix it).
