Patch that adds the MovementBottomEdge property

USECASE:
My Synaptics touchpad has physical buttons below the bottom edge of its surface. As a result, when I try to perform a click by pressing the bottom edge of the touchpad I get both a click and a movement. This often causes the click to take place after the movement thus causing me to click on the wrong icon, button, etc.

PROPOSED SOLUTION:
The driver should allow the deactivation of movements in the area over the physical buttons.

EXPLANATION:
As you can see in the attached patch, I have implemented the support for a "MovementBottomEdge" option which, if set through either xorg.conf, synclient or xinput, allows users to blacklist the area of the touchpad below the value set in this option.

For example to set the new property to "4100" through Xinput you will have to type:
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Movement Bottom Edge" 32 4100

to disable it:
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Movement Bottom Edge" 32 0

The "MovementBottomEdge" property is set to 0 (hence disabled) by default, therefore no one will notice a change in the behaviour of their touchpad unless they manually set this option.

Please consider accepting my patch and let me know if you would like me to change it or rewrite it in a way that you deem more appropriate.
