ps2 synaptics: implement 'extended W' mode.

"Newer" synaptics touchpad support a new mode where they can report more
information to the host. In this mode, there is a different packet
format for tracking extra data from the touchpad, including a wheel
encoder (mousewheel) if available, and multitouch finger tracking.

This mode is documented in the Synaptics touchpad interfacing guide
(Synaptics document 511-000275-01 Rev. B), but was not yet implemented
in our driver.

It should help with detecting multiple fingers, or finger position on
clickpads to determine right or left click.

This change implements the following items from the Synaptics
interfacing guide:

- Cleanup and clarify the code for features detection to properly report
clickpads
- Enable "extended W" mode if supported
- Process extended W values 0 (mouse wheels, reported in the
touchpad_event structure and could be used by input_server for
scrolling), 1 (secondary finger), and 2 (finger count)
- Fix handling of wValue, which is not always a finger width
- Add handling of vValuen which indicates the finger width when wValue
doesn't

Overall, this should provide the movement_maker with a better picture of
what's happening.

Also improve tracing to show received packets and the corresponding
WValue since that's an important value in identifying which type of
packet it is.

Unfortunately I currently don't have a laptop with synaptics touchpad to
test this with.

Refactor touchpad movement generation by migrating MovementMaker to userland.

This considerably overhauls touchpad event generation, simplifying and
cleaning it up considerably:

* Return the touchpad specifications through the MS_IS_TOUCHPAD ioctl.

* There is now a dedicated MS_READ_TOUCHPAD ioctl, as touchpads
can either return touchpad_movement structures or mouse_movement
ones depending on what mode they are operating in.

* Event repeating on timeouts is now handled in MovementMaker and
the input_server control thread, so MS_READ_TOUCHPAD takes
a timeout value. This means we can drop all the EventProducers.

* Use the real floating-point math functions in MovementMaker now
that we are running in userland.

* Drop unused structures, constants, headers, and other things
related to touchpad support.

PS/2 synaptics: minimal clickpad support

Handled as a 1-button mouse. We didn't really support this since the old
Macintosh ADB mouses, so let's see if that code aged well!

ps2_synaptics: support Lenovo use of extra buttons

On some Thinkpads, the extra buttons are used for the trackpoint, so
they should be reported as "main" buttons, not extended ones. An
(undocumented) information query was added to the firmware to report
when this is the case, however it is not advertised as supported by the
firmware itself by the usual mechanism.

What we do is (just as the Linux driver) detect that the tocuhpad has a
PS/2 passthrough (likely used to daisy-chain a trackpoint on the same
PS/2 port) and also advertises extra buttons (an unlikely case, it is
already uncommon to even get a middle button these days...) and assume
that the information query is available then.

When the query is available and reports the quirk, the extended buttons
are reported as 0, 1, 2 (left, right, middle), instead of extra buttons
the userland would have no idea what to do with.

PS/2 Synaptics: add support for extended buttons

It is possible to get up to 8 extra buttons on synaptics touchpads.
On some Thinkpad models, these are used to implement the trackpoint
buttons (reported as buttons 4, 5 and 6). Since the touchpad itself has
no buttons (it is a clickpad), we may at least try to handle these
properly.

- ALPS and synaptics are sharing the same code to generate mouse events now. The movement generation is calibrated on the synaptics touchpad, though.
ALPS movements are fine now, hope the synaptics is still working. Please test! There are still some leftovers form switching from a c struct to a c++
class will fix that later.
- Support ALPS devices with passthrough.
- ALPS is still disabled because tap and edge motion is not working yet. The
problem is that synaptics generates more helper events which makes this a lot
easier to implement. My plan is to emulate this events to imitate the synatics touchpad.
