ALQ (Asynch. Logging Queues). ALQ supports many seperate queues with
different record and buffer sizes. It opens and logs to any vnode so
it can be used with character devices as well as regular files.

According to the MII specification, the delay produced by our
reads alone are sufficient for correct operation.
This reduces the time mii_tick takes from 10ms to ~1ms here. That's
still a lot, but much better than before.

This makes it trivial to map the stack non-executable for certain abis, on

getting prior review on a patch like this is not feasible, considering
the number of people involved and hardware availability etc.)
If struct disklabel is the messenger: kill the messenger.
Inside struct disk we had a struct disklabel which disk drivers used to
communicate certain metrics to the disklayer above (GEOM or the disk
mini-layer). This commit changes this communication to use four
explicit fields instead.
Amongst the benefits is that the fields do not get overwritten by
wrong or bogus on-disk disklabels.
Once that is clear, <sys/disk.h> which is included in the drivers
no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in,
the few places that needs them, have gotten explicit #includes for
them.
The disklabel inside struct disk is now only for internal use in
the disk mini-layer, so instead of embedding it, we malloc it as
we need it.
This concludes (modulus any mistakes) the series of disklabel related
commits.
I belive it all amounts to a NOP for all the rest of you :-)

- Get test for valid trace request contents right.
- You don't use 'stq' to move a value from one register to another,
use 'mov' to read sp. Also, can't use nice names for registers
in in-line asm in gcc.
- pc is not a publically accessible register, instead, create a label
in the asm code and use 'lda' to load the address of that label into
the pc field of the trace request.
- Use correction function name for db_print_backtrace().

valuable panic messages off of the screen. This option can be turned on
by the DDB_TRACE kernel option as well as the debug.trace_on_panic sysctl.
Also, fix the DDB_UNATTENDED option to use its own header instead of
abusing opt_ddb.h. This way turning that one option on or off doesn't
force you to recompile all of ddb.
