Create a script for gathering latency data for the whole uTouch stack

[Duncan McGreggor]

Depends on:
  bug #622690
  bug #622752

Once we have a virtual mt device, we can start gathering data on latency between stack components. We need a script that can do the following:
 * send gesture data between <kernel, x> <x, grail>, <grail, geis>, <geis, unity>, <kernel, unity>
 * measure the time (high-resolution) the sends/receives take
 * present this data in a machine-readable format (definitely stdout, maybe also write to disk)

Gesturetest is obsolete. Closing bug report.
