+ do not release the dma-ble region used for downloading firmware.
This should fix the problems that some people were seeing, due to
memory becoming too fragmented which prevented subsequent allocations
of a suitable contiguous region of memory;
+ document the firmware format and usage in if_iwivar.h
+ use a loop to allocate the four tx rings, instead of replicating
the body of the loop.
+ add debugging code IWI_LOCK_ASSERT() to detect missing locks.
These only do a printf, and should go away once we figure out why
the driver sometimes freezes the system due to a (yet unidentified)
race condition.
+ add a device_printf() in iwi_ioctl() in certain conditions
(see comment in the code). This helps preventing the race condition
mentioned above, and makes the system survive. This printf will
also go away once fixing this bug is completed.
+ change iwi_getfw() to return 0 on success, 1 on error, consistently
with other functions.
+ fix the argument of a sizeof() in iwi_get_firmware()
+ use le32toh() to access little-endian fields
+ simplify error handling in iwi_load_firmware() and iwi_init_locked()

Sweep kernel replacing suser(9) calls with priv(9) calls, assigning
specific privilege names to a broad range of privileges. These may
require some future tweaking.

This restores fine-grained privilege support to System V IPC.

ignored on other systems I investigated when accessing an existing
memory segment rather than creating a new one. This call to ipcperm()
is the only one to pass in a complete mode flag to the permission
checks rather than a simple access request mask, and caused problems
for the revised ipcperm() based on the priv(9) interface, which can
now be restored.

VFS privilege namespace: exceedquota, getquota, and setquota. Leave
UFS-specific quota configuration privileges in the UFS name space.
This renumbers VFS and UFS privileges, so requires rebuilding modules
if you are using security policies aware of privilege identifiers.
This is likely no one at this point since none of the committed MAC
policies use the privilege checks.
set real-time priority on a thread. It looks like this suser(9)
call was introduced after my first pass through replacing superuser
checks with named privilege checks.
As consequence, getdirentries() no longer needs to drop/reacquire
directory vnode lock, that would allow it to be reclaimed in between.
