Since the state name is an optional argument, it often can conflict
with other options. To avoid ambiguity now the state name must be
prefixed with a colon.

I moved this branch from github to a private server, and pulled from the
wrong one when committing r315280, so I failed to include two recent commits.
Thankfully, they were only cosmetic and were included in the review.
Specifically:
Add documentation, polish comments, and improve style(9).

inet_ntoa() and inet_ntoa_r() take the address in network
byte-order. When I removed those calls, I should have
replaced them with ntohl() to make the hex addresses slightly
less unreadable. Here they are.
See r315277 regarding classic blunders.

POSIX 2008 says this about clock_settime(2):
If the value of the CLOCK_REALTIME clock is set via clock_settime(),
the new value of the clock shall be used to determine the time
of expiration for absolute time services based upon the
CLOCK_REALTIME clock. This applies to the time at which armed
absolute timers expire. If the absolute time requested at the
invocation of such a time service is before the new value of
the clock, the time service shall expire immediately as if the
clock had reached the requested time normally.
Setting the value of the CLOCK_REALTIME clock via clock_settime()
shall have no effect on threads that are blocked waiting for
a relative time service based upon this clock, including the
nanosleep() function; nor on the expiration of relative timers
based upon this clock. Consequently, these time services shall
expire when the requested relative interval elapses, independently
of the new or old value of the clock.
When the real-time clock is adjusted, such as by clock_settime(3),
wake any threads sleeping until an absolute real-clock time.
Such a sleep is indicated by a non-zero td_rtcgen. The sleep functions
will set that field to zero and return zero to tell the caller
to reevaluate its sleep duration based on the new value of the clock.
At present, this affects the following functions:
pthread_cond_timedwait(3)
pthread_mutex_timedlock(3)
pthread_rwlock_timedrdlock(3)
pthread_rwlock_timedwrlock(3)
sem_timedwait(3)
sem_clockwait_np(3)
I'm working on adding clock_nanosleep(2), which will also be affected.

When I made the changes in r313821, I fell victim to one of the
classic blunders, the most famous of which is: never get involved
in a land war in Asia. But only slightly less well known is this:
Keep your brain turned on and engaged when making a tedious, sweeping,
mechanical change. KTR can correctly log the immediate integral values
passed to it, as well as constant strings, but not non-constant strings,
since they might change by the time ktrdump retrieves them.

It was implemented to reduce context switches when uploading firmware to
card's RAM. But this mechanism is not used last 10 years since all mbox
operations are now polled, and it was never used for cards produced in
last 15 years. Newer cards can use DMA to upload firmware.

With the following in /etc/fstab:
/dev/gpt/swap.eli none swap sw,late 0 0
swap will not be enabled, with `swapon -aL' complaining:
swapon: Invalid option: late
This happens because swap_on_geli_args() which parses geli arguments
out of all mount options does not expect late or noauto among them.
Fix this by explicitly allowing these arguments.

This change fixes DMA resource leak on driver unload. Also it removes
DMA resources allocation for hardcoded number of requests before fetching
the real number from firmware. Also it prepares ground for more flexible
