Properly handle version of the protocol where standard PS/2 packets
from trackpoint are stuffed into middle (byte 3-6) of the standard
ALPS packets when both the touchpad and trackpoint are used together.

The patch is based on work done by Matthew Chapman and additional
research done by David Kubicek and Erik Osterholm:

Many thanks to David Kubicek for his efforts in researching fine points
of this new version of the protocol, especially interaction between pad
and stick in these models.

The touchpad on Acer Aspire 5720, 5520 and some other Aspire models
(signature 0x73, 0x02, 0x50) has a button that can be rocked in 4
different directions. Make the driver to generate BTN_0..BTN_3 events
in response. The Synaptics driver by default maps BTN_0 and BTN_1 to
up and down, so there should be no visible changes with the old setup
that generated BTN_FORWARD and BTN_BACK (also mapped to up and down).

Do not start protocol detection assuming that middle mouse is present,
instead let individual protocols explicitly set this capability.

Commit b7802c5c ("Input: psmouse - use boolean type") caused the
synaptics_hardware variable to be completely useless, as it is
constantly set to 'true' throughout the whole psmouse_extensions().
This was caused by the following hunk in the commit in question

	-       int synaptics_hardware = 0;
	+       bool synaptics_hardware = true;

which is wrong and causes driver to issue extra reset when falling
back to bare PS/2 protocol.

The serio ports on i8042 are not completely isolated; while we provide
enough locking to ensure proper serialization when accessing control
and data registers AUX and KBD ports can still have an effect on each
other on PS/2 protocol level. The most prominent effect is that
issuing a command for the device connected to one port may cause
abort of the command currently executing by the device connected to
another port.

Since i8042 nor serio subsystem are not aware of the details of the
PS/2 protocol (length of the commands and their replies and so on) the
locking should be done on libps2 level by adding special handling when
we see that we are dealing with serio port on i8042.

The OLPC XO laptop incorporates a combination touchpad/tablet device
which unfortunately requires frequent recalibration.  The driver will
force this automatically when various suspicious behaviors are
observed, and the user can recalibrate manually (with a special
keyboard sequence). There's currently no way, however, for an external
program to cause recalibration. We can not use the reconnect
capability which is already available in /sys because full reset of
the touchpad takes 1.1 - 1.2 secons which is too long.

This patch creates a new node in /sys which, when written with '1',
will force a touchpad recalibration; no other writes (or reads)
of this node are supported.

The appletouch driver is prone to reporting multiple fingers when only
one is pressing.  The appletouch driver queries an array of pressure
sensors and counts local maxima in pressure to determine the number of
fingers.  It just does this on the raw values, so a data stream like:

0 100 250 300 299 300 250 100 0

actually registers as 2 fingers.

This patch updates the logic to ignore small dips in pressure that are
less than the threshold.

It appears that when the XO touchpad unit resets from ESD, it sends AA
AA instead of AA 00, the psmouse-base code handles the case of AA 00 by
triggering a serio reconnect for the port, causing a full reprobe of
the device.

Testing with OFW shows that this is likely to solve the problem, so
the attached patch simply expands the existing test to also catch AA AA.
