Add two another workarounds for carp(4) interfaces:
- do not add connected route when address is assigned to carp(4) interface
- do not add connected route when other interface goes down
Embrace workarounds with #ifdef DEV_CARP
(like an EC/SMbus controller) to access the EC address space. Access
is synchronized by the EcLock/Unlock routines in EcSpaceHandler().

configure_final(), assert that "cold" is true in usb_cold_explore()
when there are busses to explore. When USB is kldloaded after boot,
usb_cold_explore() will still get invoked but the list of busses
to explore in that case should always be empty.
transfer, which lead to panics or page faults. For example if a
transfer timed out, another thread could come along and attempt to
abort the same transfer while the timeout task was sleeping in
the *_abort_xfer() function.
Add an "aborting" flag to the private transfer state in each host
controller driver and use this to ensure that the abort is only
executed once. Also prioritise normal abort requests over timeouts
so that the callback is always given a status of USB_CANCELLED even
if the timeout-initiated abort began first.
The crashes caused by this bug were mainly reported in connection
with lpd printing to a USB printer.

inevitable component in Sun Exx00 machines and provides serial ports,
NVRAM and TOD amongst others which are handled by uart(4) and eeprom(4)
respectively). This driver currently only prints out information about
the chassis on attach and allows to blink the 'Cycling' LED (which is
duplicated on the front panel) of the clock board just like fhc(4) does
for the other boards. The device name for the LED is /dev/led/clockboard.

- Correctly handle pass-through allocations in fhc_alloc_resource().
- In case the board model can't be determined just print "unknown model"
so the physical slot number is reported in any case.
- Add support for blinking the 'Cycling' LED of boards on a fhc(4) hanging
of off the nexus (i.e. all boards except the clock board) via led(4).
All boards have at least 3 controllable status LEDs, 'Power', 'Failure'
and 'Cycling'. While the 'Cycling' LED is suitable for signaling from
the OS the others are better off being controlled by the firmware.
The device name for the 'Cycling' LED of each board is /dev/led/boardX
where X is the physical slot number of the board. [1]

This is mentioned in the Handbook but it is not as obvious to new
users why bpf is needed compared to the other largely self-explanatory
items in GENERIC.
