Summary

Although patch is rather big, it mostly consists of multitouch code
refactoring required to import EBM-solver implementation from OpenBSD
and of EBM-solver itself which is required for touch tracking.

"Touch tracking is a process of assignment of unique trackingID to each
initiated contact on the surface. Keeping the trackingIDs persistent
across multitouch reports requires solving of so called Euclidian
Bipartite Matching problem."
