Peter Hutterer 2248c3eab6 touchpad: support automatic drag-lock when releasing at the edge ...

If drag-lock is disabled but we're in a tap-and-drag state and the
finger is released near the edge (within 5mm), enable automatic drag
lock for 400ms.  This allows a user to quickly reset the finger and
continue with the drag.

The 400ms is a randomly guessed timeout - if you're using tap-and-drag
without draglock, finger dexterity should be high enough that resetting
the single finger can be done quickly but it's also short enough to not
make the occasional delayed button be painful in day-to-day use.
