firewire: force root change when root node is not cycle master capable
When a FireWire bus resets, all devices negotiate who is the new boss.
when we detect the root node can't be cycle master,
we send a PHY config packet that forces a reelection.

firewire: add warn-only CRC validation for CSR ROM directories
Implemented crom_crc_valid() helper to validate IEEE 1394 config ROM CRC-16
checksums.
Skipped root header CRC validation since csrhdr.crc_len cover the entire
ROM body which is not fully read at header parse time. Per-directory
CRC checks below catch corruption where it needed.

net80211: update drivers to allocate sequence numbers in the raw path
A bunch of drivers weren't properly converted. I mistakenly
put a call to ieee80211_output_seqno_assign() wherever the
crypto header was added, which isn't exactly correct.
There are plenty of drivers which don't share enough of their
raw and normal transmit path code for that to hold true.
So after some manual review, it looks like I've captured the
places (outside of iwn(4) which I committed earlier) where
I missed ieee80211_output_seqno_assign() calls.
* For bwi(4) and bwn(4) I refactored it out into a place that is
common enough and happens in the same lock hold window,
so it's serialised.
* For the rest, it's just plain missing from the raw path.

aq(4): Document the Atlantic 2 (AQC113/114/115/116) devices
List every AQC part aq_vendor_info_array[] probes, each with the
maximum speed aq_hw_capabilities() grants it.
Only the Atlantic 2 parts link at 10 Megabit. The AQC100 and AQC100S
are the only SFP+ controllers; the rest are twisted pair.

amd64: FRED support
FRED support as defined starting from the SDM rev. 90, requires a new
'events' entry point to receive user and kernel mode exceptions and
interrupts notifications from the hardware. A minimal asm trampoline is
enough, rest can be implemented in C due to the clean FRED organization
of the event reporting.
The syscall entry is handled by a microptimized assembly path, directly
calling into the amd64_syscall() handler, instead of the generic events
entry point.

vtfontcvt: Avoid dead store in add_char
The fallback glyph is stored at index 0, and does not need to be
inserted into a mapping.
Previously there was a dead store of add_glyph's return value for the
fallback case, which upset Clang's static analyzer. Now, cast the
return value to (void) to make it clear this is intentional.
Also change add_glyph's fallback parameter to a c99 bool to make its use
more clear.
