hw.synaptics.aux_mid_button_scroll translates vertical movements
of an aux device (like a trackpoint) into a scroll event when
the middle mouse button is pressed.

Make this work with either the middle mouse button of the main
device (buttonmask 0x02) or the middle mouse button of the aux
device (buttonmask 0x40).

Fixes PR 58435.

Print raw input for debugging.

Correct capability parsing. Old devices were probed with nonexistent
commands and then used undefined boundary values that made them unusuable.

Use the original right boundary when calculating the vertical scroll
region so the boundary does not creep left on each subsequent setting.

Fix regression introduced when fixing PR kern/56613 and related tweaks

* A trackpad with external buttons needs to mask a number of lower bits
of the X and Y coordinates IFF a button is down. This was not being
done so a button held down looked like an out of range packet and
was therefore dropped.

* Now that trackpads are probed for their boundaries make the emulated
button boundary settable by a percentage, also allow the right and
bottom boundaries to be adjusted by a percentage to allow for
horizontal and vertical scroll regions.

Fix for PR kern/56613

* For trackpads that report max and min coordinates, retrieve these and
use them as the boundaries instead of the hard coded limits.
* Drop packets that are have x/y values that are outside the limits of
the trackpad. Some trackpads report a stream of low values in some
situations that cause cursor jumping.

synaptics: Fix tracking of extended buttons.

- Ensure that packets are processed whenever any button change
occurs, instead of just processing packets when there is movement
or trackpad finger activity
- Only transfer the state of the "extended buttons" to the button
masks when actual changes occur OR a button is being held down.

With this patch, my middle mouse button no longer gets "stuck down",
but proper press/release tracking and dragging behavior is preserved.

Significant update to the synaptics touchpad driver.

* Accumulate packets for primary, secondary, finger count packets
before handing off to pms_synaptics_process_packet. This means
that both primary and, possibly, secondary finger locations will
be processed at the same time. Previously the processing each
packet as it arrived.

* Fix the secondary finger position reporting, there was an off by
one in the shifts when decoding which effectively halved the
reported position.

* For a clickpad, make the emulated button region "dead" so that finger
movements in this region are ignored. This makes it easier to click
a button without accidentally repositioning the cursor. There is a
sysctl variable "button_region_movement_enable" that will allow
these finger movements to be reported if this is desirable.

* Reset the finger ballistics when the number of fingers changes. This
stops the annoying position jumps when a second finger touch is added
to or removed from the touchpad.

* Add a level argument to the DPRINTF macro so one can choose their
level of debug spam via the debug sysctl variable.

Extended buttons are reported separate from touchpad buttons, so track
button press / release state separate from touch events.

I now have smooth two-finger scrolling.

I suspect this code doesn't make any sense if we want two-finger scrolling
