man4: Install mgb.4 on all architectures
mgb(4) is not x86-only now, so install its manpage everywhere and make
if_mgb.4 link creation work, which is already on all architectures.

dhclient: Add some regression tests
Add tests for some recently fixed bugs in dhclient. All of these tests
set up two VNET jails connected by an epair. dhclient runs in one jail,
and the test code runs on the other end. It uses scapy to inject
"interesting" packets in response to DHCPDISCOVER messages from
dhclient, then checks the configured interface and lease file.

tests/sys/kern: stress FP registers across sigreturn on powerpc64
This is the program that found the races fixed in 1f1043d550ea. One
thread keeps a pattern in f14-f31 across a signal, while helpers pinned
to the same CPU keep different patterns in the real registers and get
woken up from another CPU to preempt it at random points. If the kernel
ever hands it somebody else's registers, the pattern doesn't match.
The register loads, the thr_kill() and the handshake with the helper are
in assembly so that nothing touches the FP registers between sigreturn
and the check. It runs for ten seconds and is skipped with fewer than
two CPUs.

powerpc64: give each CPU its own KDB trap stack
Kernel mode program, trace, breakpoint and machine check exceptions go
through dbtrap, which saves the registers on trapstk and, if KDB doesn't
want the trap, restores them from there and continues with the normal
trap handler. There was just one trapstk for all CPUs, so when two of
them trapped at the same time they overwrote each other's frame and one
of them carried on with the other's registers. DTrace fbt probes are
these traps, so a probe on a function that runs on several CPUs at once
took the kernel down within seconds.
Keep the stack in the pcpu instead. The boot CPU gets a static one,
since it's set up before malloc works, the others allocate theirs in
cpu_pcpu_init() like the Book-E critical interrupt stack.

rtld: add .cfi_undefined lr to rtld_start.S on powerpc*
Without it, LLVM libunwind doesn't know where to stop when unwinding the
main thread, so it uses a stale LR as the return address and crashes.
Our libunwind doesn't do that since 5866c369e4fd reverted it, but
programs that bundle their own copy, like ClickHouse, are hit by it.
amd64, arm64, i386 and riscv already have the same annotation.

ggate: fix test intermittency
* ggatel: fix piped output. Flush stdout before daemonizing, so the
output can be read when it's in a command pipeline.
* ggated: bind the port _before_ daemonizing, so an invoking script can
be sure that the port is bound as soon as the command returns.
* tests: allow ggatec or ggatel to automatically allocate a device
number instead of choosing one in a racy way.
With all of these changes I can no run the tests 1000 times without
fail. And in parallel, too.

virtio_gpu: use an X8R8G8B8 resource on big-endian guests
The virtio-gpu resource formats are defined by byte order in memory,
while vt(4) and the X server (through vt_fb and the fb mmap) write
native 32-bit 0x00RRGGBB pixels into the shadow framebuffer. On a
big-endian guest such as powerpc64 those pixels land in memory as
00 RR GG BB, which the host interprets under B8G8R8X8 with red and
blue swapped and the padding byte taken as blue: white renders yellow
and blue renders black.
Request X8R8G8B8 on big-endian guests instead, which is also what the
Linux driver does (DRM_FORMAT_HOST_XRGB8888). Reproduced with a colour
test pattern on a powerpc64 QEMU pseries guest using the identically
coded out-of-tree fork of this driver (graphics/virtio-gpu-qemu-kmod);
little-endian guests are unchanged.

iwm: update phy context routines; add HT channel width parameter
Update the phy context routines to match what the openbsd snapshot
is doing. This involves some HT channel width stuff which although
I am not doing HT right now, it was juts easier to sync these
entirely versus just a partial sync.
* Update the phy context routines to match what openbsd is doing
* Although the openbsd driver has an iwm_phy_ctxt_update() routine
instead of add and modify, I'm leaving it as-is for now.
A bunch of refactoring is going to need to be done to properly
use an iwm_phy_ctxt_update() call and I didn't want to tackle
that in here.
* Add a UHB firmware capability phy context call; I can't test it
but it's mostly copy/paste.
* Add in a util to turn ieee80211_channel into the 'sco' variable
(the HT low/hi parameter) since it's done in openbsd in a
slightly different way.
