76b008123e Add ontop of my existing boot loader Forth code, including support for
submenus. See menusets.4th(8) for additional details including examples.

Discussed on arch and recommended for inclusion at the devsummit.

This change does not alter the appearance or user experience, only enhances
possibilities.

451c63e727 Remove the tid from the software table (and bump down the in-use
counter) when the syncache doesn't want the driver to reply to an
incoming SYN.  This fixes a harmless bug where tids_in_use would
go out of sync with the hardware counter.

8981e79fb5 Convert the aggregate descriptor path over to use the same API as
the non-aggregate path.

I "cheated" by using some TX setup code in our HAL that isn't present
in the atheros HAL (or Linux ath9k.)

The old path for forming aggregates was:

* setup the rate control in the first descriptor;
* call chaintxdesc() on all the frames;
* call setupfirsttxdesc() on the first descrpitor in the first
  frame;
* call setuplasttxdesc() on the last descriptor in the last frame.

The new path for forming aggregates looks like the non-aggregate path:

* call setuptxdesc() on the first descriptor in the first frame;
* setup the rate control in the first descriptor;
* call filltxdesc() on each descriptor in the frame;
* if it's an aggregate - call set11n_aggr_{first, middle, last} as
  appropriate (see the code for a description of what is "appropriate".)

Now, this is done primarily for the AR9300 HAL - it doesn't implement
the first set of aggregate functions.  It just has the older methods
and the "first/middle/last" aggregate methods.  So, let's convert the
code to use these.

Note: the AR5416 HAL in FreeBSD had that code (from me, a while ago)
and a previous commit brought it up to behave the same as the AR9300
HAL routines.

There's some further tidyups to be done - specifically, avoid doing
multiple calls to the 11n descriptor functions. I shouldn't call
clr11n_aggr(), then set11n_aggr_middle(), then also set11n_aggr_first().
On (at least MIPS) the TX descriptors are in non-cachable memory and
this will cause multiple slow writes.

I'll debug/tidy that up in a future commit.

Tested:

* AR9280, STA
* AR9280/AR9160, AP
* AR9380, STA (using a local, closed source HAL, sorry!)

a985eb3b40 Add the UQ_MSC_NO_PREVENT_ALLOW quirk to handle devices that do not support
the 'PREVENT/ALLOW MEDIUM REMOVAL' SCSI command. An example of such a
device is the STmicro ST72682. We send the SCSI command for every open and
close, which can result in a significant amount of spam on the console
during boot.

373133f0ad Remove duplicate const specifiers in many drivers (I hope I got all of
them, please let me know if not).  Most of these are of the form:

static const struct bzzt_type {
	[...list of members...]
} const bzzt_devs[] = {
	[...list of initializers...]
};

The second const is unnecessary, as arrays cannot be modified anyway,
and if the elements are const, the whole thing is const automatically
(e.g. it is placed in .rodata).

I have verified this does not change the binary output of a full kernel
build (except for build timestamps embedded in the object files).

2.  Make sure to flush the dcache after writing the TLB1 entries

    just yet.
3.  Set pmap_bootstrapped after calling pmap_bootstrap(). The
