This update corrects an error where fsck_ffs miscalculated the last

Experimentally, reduces sort -R time of a 148160 line corpus from about
3.15s to about 0.93s on this particular system.
There's probably room for improvement using some digest other than md5, but
I don't want to look at sort(1) anymore. Some discussion of other possible
improvements in the Test Plan section of the Differential.

Summary:
Initial NUMA support:
- associate CPU with domain
- associate memory ranges with domain
- identify domain for devices
- limit device interrupt binding to appropriate domain
- Additionally fixes a bug in the setting of Maxmem which led to
only memory attached to the first socket being enabled for DMA
A pmap variant can opt in to numa support by by calling `numa_mem_regions`
at the end of pmap_bootstrap - registering the corresponding ranges with the
VM.
This yields a ~20% improvement in build times of llvm on dual socket POWER9
over non-NUMA.

Fix some execution bugs in the dtrace powerpc asm. addme pulls in the carry
flag which we don't want, and the result wasn't recorded anyways, so the
following beq to check for exit condition wasn't checking the right
condition.
Simplify the stack walking in dtrace_isa.c, so there's only a single walker
that handles both pc and sp. This should make it easier to follow, and any
bugfix that may be needed for walking only needs to be made in one place
instead of two now.

Forgot to add the changes for DELAY(), which lowers priority during the
delay period. Also, mark the timebase read as volatile so newer GCC does

PowerISA 2.07 and PowerISA 3.0 both specify special NOPs for priority
adjustments, with "medium" priority being normal. We had been setting
medium-low as our normal priority. Rather than guess each time as to what
we want and the right NOP, wrap them in inline functions, and replace the
occurrances of the NOPs with the functions. Also, make DELAY() drop to very
low priority while waiting, so we don't burn CPU.
Coupled with r346143, this shaves off a modest 5-8% on buildworld times with
-j72. There may be more room for improvement with judicious use of these
NOPs.

The POWER9 documentation specifies that levels 0-3 are the 'lightest' sleep
level, meaning lowest latency and with no state loss. However, state 3 is
not implemented, and is instead reserved for future chips. This now
properly configures the PSSCR, specifying state 2 as the lowest level to
enter, but request level 0 for quickest sleep level. If the OCC determines
that the CPU can enter states 1 or 2 it will trigger the transition to those
states on demand.

It was pointed out that manually loading a .dtb to be used rather than
relying on platform-specific method for loading .dtb will result in overlays
not being applied. This was true because overlay loading was hacked into
fdt_platform_load_dtb, rather than done in a way more independent from how
the .dtb is loaded.
Instead, push overlay loading (for now) out into an
fdt_platform_load_overlays. This method easily allows ubldr to pull in any
fdt_overlays specified in the ub env, and omits overlay-checking on
platforms where they're not tested and/or not desired (e.g. powerpc). If we
eventually stop caring about fdt_overlays from ubenv (if we ever cared),
this method should get chopped out in favor of just calling
fdt_load_dtb_overlays() directly.

In review D19876 ian@ has some proposed improvements to the
tools/boot/ci-qemu-test.sh script. Start specifying the location of
OVMF.fd fetched by the Cirrus-CI build in advance of those changes.
When leaving a multicast group, a hole may be created in the inpcb's
source filter and group membership arrays. To remove the hole, the
succeeding array elements are copied over by one entry. The multicast
code expects that a newly allocated array element is initialized, but
the code which shifts a tail of the array was leaving stale data
in the final entry. Fix this by explicitly reinitializing the last
entry following such a copy.

Bound input file processing length to avoid the issue reported in [1]. For
simplicity, only allow regular file and character device inputs. For
character devices, only allow /dev/random (and /dev/urandom symblink).
32 bytes of random is perfectly sufficient to seed MD5; we don't need any
more. Users that want to use large files as seeds are encouraged to truncate
those files down to an appropriate input file via tools like sha256(1).
(This does not change the sort algorithm of sort -R.)

Our home-rolled solution didn't quite capture all of the details, and we
didn't actually validate snapshot names at all. zfs_name_valid captures the
important details, but it doesn't necessarily expose the errors that we're
wanting to see in the be_validate_* functions. Validating lengths
independently, then the names, should make this a non-issue.
