Start a gentle API change by exposing utouch-frame through grail,
and deprecating the grail_contact struct. Old programs compile and
run fine. To only use the new api, compile with -DGRAIL_NO_LEGACY_API.

Remove the grail-internal mapping code and rely directly on
utouch-frame instead. Passes the unit test designed for this
change.

The original grail uses an internal touch framework and exports some
touch information as extended attributes to gesture events. This was
never quite the intention, but rather to expose gestures and touches
on a similar footing, such that grail can be input agnostic. This
patch starts off by replacing the internal touch framework with the
utouch-frame engine.

The current grail operates via callbacks. In order to make grail work
as a pipe, where input and output can be controlled externally, add
the missing event queue for gestures, and align the code to simplify a
switch.

Add the five first contacts to the property list, and unify the
handling of all gesture types in this regard. To avoid duplication,
move the scaling of properties closer to the gesture recognizer.
Move all gesture event handling code to grail-event.c, simplifying
the structure somewhat.

This patch adds the possibility to extract the current set of
contacts from the grail state.
