Simple stuff
------------
Split _download up so that the MIB settings are in their own functions.
Made "tx completed but status is ..." a recoverable error
Cut down verbosity of "unloaded" messages
Moved ccs_free and com_runq from intr_ccs to ecf_done and runq_done

Consistnet debugging around tsleeps.

com_malloc is now seperated from the comq initialization. This was
done whilst trying to set automatic variables for the comqs.
Harder Stuff
------------
As part of the IFF_RUNNING fixes, remove the panic in runq if we are
not running.
Change, again, runq_add. This time we don't do any cleaning up
if there were errors. This is so that callers get the chance
to re-try (not that I ever see it being used).
In runq_add, only sleep when there is something to sleep on!
ioctl locking routines, stolen from awi.c but not used
Hardest Stuff
-------------
Dealing with serialing ioctls correctly means that we must QUEUE
changes to IFF_RUNNING and check it in the QUEUED commands, not
in the user commands. Whilst simple to state, it took a few
hours of head scratching to get it right. The realisation was that
I only have to guarantee that sub-commands from a single process
are serialised and "atomic", and that they check the status of the
interface flags when invoked and not when they are queued.
Another way of looking at it, is that the driver's state is stored
in the runq and the IFF_RUNNING flag. These must be changed together.
What this means practically, is that IFF_RUNNING is set after
we have started/joined/associated with a network. And it is
cleared by ray_stop via the runq so that unfinsished commands are
not distrupted.
I still have to fix up promisc, upp/repparams and mcast.
Oh yeah, stop is essentially a noop in that it only
changes IFF_RUNNING

to various pmap_*() functions instead of looking up the physical address
and passing that. In many cases, the first thing the pmap code was doing
was going to a lot of trouble to get back the original vm_page_t, or
it's shadow pv_table entry.
Inspired by: John Dyson's 1998 patches.
Also:
Eliminate pv_table as a seperate thing and build it into a machine
dependent part of vm_page_t. This eliminates having a seperate set of
structions that shadow each other in a 1:1 fashion that we often went to
a lot of trouble to translate from one to the other. (see above)
This happens to save 4 bytes of physical memory for each page in the
system. (8 bytes on the Alpha).
Eliminate the use of the phys_avail[] array to determine if a page is
managed (ie: it has pv_entries etc). Store this information in a flag.
Things like device_pager set it because they create vm_page_t's on the
fly that do not have pv_entries. This makes it easier to "unmanage" a
page of physical memory (this will be taken advantage of in subsequent
commits).
Add a function to add a new page to the freelist. This could be used
for reclaiming the previously wasted pages left over from preloaded
loader(8) files.

53C810 non 'A', 53C815 and 53C825 non 'A' are now

When both `ncr' and `sym' are configured, `sym'
will now attach all the 53C8XX devices by default.
Previous balancing between `ncr' and `sym' can be

- Reorganize the probe/attach stuff using newbus. Each XMAC is now
