First draft of the patch

The attached patch is a just first draft and I haven't touched the man page yet.

HOW IT WORKS:
When values other than 0 are assigned to the "Synaptics Area" property, taps, scrolling and movements are allowed only in the "Synaptics Area".

For example, if I set the bottom edge of the area to 3700:
xinput set-int-prop $YOUR_DEVICE_ID "Synaptics Area" 32 0 0 0 3700

the active area will be a rectangle which has the top, left and right physical edges and the bottom edge of the area (3700) as its limits. Of course it is also possible to use custom values for all the 4 edges of the area so as to create an area whose borders don't match with the physical ones.

NOTE: The line which begins with "if ((dx || dy) && (is_inside_active_area" is necessary only if we disable taps, in order to prevent the cursor from jumping. Maybe there's a better way to disable taps (?).

Let me know what you think.
