reconstructed from a tcpcb when needed.
Previously, tcp templates required the allocation of one
mbuf per connection. On large systems, this change should
free up a large number of mbufs.

functions in ifconfig. "ifconfig an0" should output the correct
status now. Also, make the read and write functions both more
robust and more consistant. This should stop most of the incorrect
size complaints and eliminate the possiability of panics from firmware
that increases resource sizes.

- Clean up KTR_PROC tracepoints to not display the value of

the messages.

- Remove spl's rom asleep and await as the proc lock and sched_lock provide
all the needed locking.
- In mawait() add in a needed ktrace point for noting that we are about to
switch out.

Set maintainer to myself. This needs to stay in sync with what Buntils
does, and it would be best to pass functionality changes thru me to make
sure future plans are taken into account.
