be dying shortly.
These programs will not be a part of 5.0-RELEASE, at least not in their
current form. They'll either end up in src/contrib or ports.

I don't know if people think that these debugging macros are worth keeping
or not but I'll keep them for a short while, while the danger of
queue stuffups in the (rather complicated) run queue code exists.
This removes a bad latency problem during initial setup where we
end up waiting for too long before reading the connected message
and time the connection out.

NOTE: this is still Beta code, and contains lots of debugging stuff.

- Statically size the bpvo entries to avoid conflicts between bpvo allocation
and the vm allocator.
- Shift pmap_init2 code into pmap_init.
- Add UMA_ZONE_VM flag to uma_zcreate.

The case in cpu_switch() where there isn't a higher priority thread
(choosethread() == curthread) uses r4 as the PCB context pointer. However, the
use of r4 after the label L2 is incorrect, since it was probably trashed by
the call to choosethread, and in any case was set up to curthread at the start
of the routine.
This condition will occur when an interrupt thread schedules a netisr, which
is a lower priority thread.
Another (probably unnecessary) difference is that I was paranoid about
register trashing, so I decided to save r2 and r13 as well.
