f4444d4a61 Another missing ! in front of IFQ_DRV_IS_EMPTY, this time in an even more 
sensitive, but less excercised location (the watchdog). While here use the
*_start_locked function directly to avoid drop, grab, drop lock.

I have to be very careful with future ALTQ patches!

756d52a195 Initialize struct pr_userreqs in new/sparse style and fill in common 
default elements in net_init_domain().

This makes it possible to grep these structures and see any bogosities.

56dd3a6182 Add optional device vnode bypass to DEVFS. 
The tunable vfs.devfs.fops controls this feature and defaults to off.

When enabled (vfs.devfs.fops=1 in loader), device vnodes opened
through a filedescriptor gets a special fops vector which instead
of the detour through the vnode layer goes directly to DEVFS.

Amongst other things this allows us to run Giant free read/write to
device drivers which have been weaned off D_NEEDGIANT.

Currently this means /dev/null, /dev/zero, disks, (and maybe the
random stuff ?)

On a 700MHz K7 machine this doubles the speed of
	dd if=/dev/zero of=/dev/null bs=1 count=1000000

This roughly translates to shaving 2usec of each read/write syscall.

The poll/kqfilter paths need more work before they are giant free,
this work is ongoing in p4::phk_bufwork

Please test this and report any problems, LORs etc.

d3cb0d99e0 Introduce two new options, "CPU private" and "no wait", to sf_buf_alloc(). 
Change the spelling of the "catch" option to be consistent with the new
options.  Implement the "no wait" option.  An implementation of the "CPU
private" for i386 will be committed at a later date.

f42a43fa2d Add basic critical section tracing to KTR using event type KTR_CRITICAL. 
This generates a KTR event for each critical section entered and exited.

It would be desirable to also log the filename and line number of the
source entering or exiting the critical section, but this requires
hacking up the critical section API, so I've not done that yet.

d6915262af Do some re-sorting of TCP pcbinfo locking and assertions: make sure to 
retain the pcbinfo lock until we're done using a pcb in the in-bound
path, as the pcbinfo lock acts as a pseuo-reference to prevent the pcb
from potentially being recycled.  Clean up assertions and make sure to
assert that the pcbinfo is locked at the head of code subsections where
it is needed.  Free the mbuf at the end of tcp_input after releasing
any held locks to reduce the time the locks are held.
