Report touch down on one-finger entry (LP: #667802)

The current code mistakenly set the pointer logic based on
the single variable, which is false at the entry to one-finger
mode, but true immediately afterwards. This leads to grail
sometimes failing to emit the proper emulation sequence, resulting
in a missed touch in X.

This patch corrects the logic such that the pointer is based directly
on one-finger mode, thereby solving the problem.

Only support pure absolute devices at this time

There are some hybrid relative/absolute devices out there, like
the magic mouse, for which special behavior, outside the current
scope of grail, is expected. This patch disables grail for those
devices.

Show all information for pass-through events

In grail-gesture, the timing information is missing. Remedied with
this patch.

Add tap state to the tapping model

Add the ability to read off the tap state in the tapping
model. Useful for emulation i lieu of tapping gestures.

Add tap emulation

Touchscreens always emit a button event when touching the
screen. Trackpads, however, are considered hovering while
touching the pad, and instead uses taps to emits button events,
which is traditionally implemented elsewhere, and thus leaves
a functionality discrepancy. This patch adds tap emulation to
grail, utilizing gesture engine.

Split pointer status and report status

Separate out reporting of the touch state, such that reporting
can be deferred. Does not introduce any logic changes.

Do not tap when leaving fingers on the pad

The current code will treat a 3-down-2-up as a tap. This patch
changes the logic so that taps are only emitted when the number of
fingers returns to the baseline.

bug: Only report position change events

This bug was introduced in v1.0.11. Only report events when
the pointer position is actually changing.
