This patch adds support for two ALPS touchpad protocols not
supported currently by the driver, which I am arbitrarily naming
version 3 and version 4. Support is single-touch only at this time,
although both protocols are capable of limited multitouch support.
Thanks to Andrew Skalski, who did the initial reverse-engineering
of the v3 protocol.

In preparation for adding support for more ALPS protocol versions,
add a field for the protocol version to the model info instead of
using a field in the flags. OLDPROTO and !OLDPROTO are now called
version 1 and version 2, repsectively.

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.

Allow ALPS, LOGIPS2PP, LIFEBOOK, TRACKPOINT and TOUCHKIT protocol
extensions of psmouse to be disabled during compilation. This will
allow users save some memory when they are sure that they will only
use a certain type of mice.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
