Implement a new ``sizedstring'' parse type for dealing with field pairs
consisting of a uint16_t followed by a data field of that size, and use
this to deal with the data_len and data fields.

use the sched_lock to protect the callout wheel in softclock() and in
the various timeout and callout functions.

16-bit mode. Technically, pcn_probe() is destructive because once the
chip goes into 32-bit mode, the only way to get it out again is a
hardware reset. And once the device is in 32-bit mode, the lnc driver
won't be able to talk to it. So if pcn_probe() is called before the
lnc probe routine, and pcn_probe() rejects the chip as one it doesn't
support, the lnc driver will be SOL.
I don't like this. I think it's a design flaw that you can't switch
the chip out of 32-bit mode once it's selected. The only 'right'
solution is for the pcn driver to support all of the PCI devices
in 32-bit mode, however I don't have samples of all the PCnet series
cards for testing.

acquire Giant as needed in functions that call mi_switch(). The releases
need to be done outside of the sched_lock to avoid potential deadlocks
from trying to acquire Giant while interrupts are disabled.

release sched_lock before calling CURSIG() in msleep() and mawait() and
reacquire it after CURSIG() returns.

tsleep(). Namely, mawait() takes an extra argument which is a mutex
to drop when going to sleep. Just as with msleep(), if the priority
argument includes the PDROP flag, then the mutex will be dropped and will
not be reacquired when the process wakes up.
- Add in a backwards compatible macro await() that passes in NULL as the
mutex argument to mawait().
except that it uses the MTX_NOSWITCH flag while it releases Giant via
mtx_exit().
- Add a mtx_recursed() primitive. This primitive should only be used on
a mutex owned by the current process. It will return non-zero if the
mutex is recursively owned, or zero otherwise.
- Add two new flags MA_RECURSED and MA_NOTRECURSED that can be used in
conjuction with MA_OWNED to control the assertion checked by mtx_assert().
- Fix some of the KTR tracepoint strings to use %p when displaying the lock
field of a mutex, which is a uintptr_t.
Remove `pmtimer' from the MFSROOT kernel as `apm' is already removed.
`pmtimer' also removed from the Alpha kernel incase it ever winds up there.
(could it ever?)
