Allocate the minimum or maximum response length for GET_BOARD_CFG as
appropriate. When looking up firmware subtypes by partition ID,
check the ID against the actual response length.

All the higher numbered functions (.2 and above) have a config space
of all 0's. This smells a bit like a special debug mode, but the
current atheros driver doesn't cope. It is unclear if this card is
just a flake, or if we're doing something wrong in the power-up
sequence.
Put a work around into the code that tests for this rather unusual
condition. If we power a CardBus device up, and the device says it is
multi-function, and any of the functions have a 0 device ID, try the
power-up sequence again.
randomdev_init_reader to change read_random over to the newly installed
adaptor was missed. This means both read_random and arc4random (seeded
from read_random) were not returning very random data. This also
effects userland arc4random as it is seeded from kernel arc4random.
The random devices are uneffected and have returned good randomness
since the change.
All keys generated with a kernel of r273872 must be regenerated with
a kernel with this patch. Keys generated may be predictable.
Remove the warning as log is too early to print anything, and it would
always get printed due to early use of arc4random...

Xenstore user-space device has two problems currently:
- It does not correctly handle concurrent clients, because it's storing
each client data in dev->si_drv1.
- It does not correctly free this data when the client closes the device.
In order to solve both of this issues store the per-client data using
cdevpriv, which also comes with a hook in order to perform the necessary
cleanup on device close.
While there also make the device eternal.

This probably supports other devices based on SeaBIOS, which need
to be added to the smbios based quirks table.
The functionality has been ported from DragonFlyBSD and adapted
to FreeBSD's more general purpose environment.
Devices not covered by a quirk shouldn't be affected at all. Thanks
to jhb and kostikbel for reviewing the code.

1. handle errors from nm_config(), if any (none of the FreeBSD drivers
currently returns an error on this function, so this change
is a no-op at this time
2. use a full memory barrier on ioctls
interrupts are enabled and the NIC is awake (think: loading a module)
then there's a not-quite-zero window where we'll get an interrupt
for the device before the attach method is called to finish setting
up the hardware.
Since I grab locks in ath_intr() to check various things, the locks
need to be ready much earlier.
