LongAndDragTrackingFilter: Unitialized member

CID 611005

* Fix regression spotted by Humdinger. Emulate right click dragging like it
used to work before, i.e right mouse button dragging works and the context
menu shows on mouse up if not dragged. I guess that at some point we'll rethink
all the mouse gestures we support and maybe simplify a bit, like dropping
long click support (as an emulated right button), and possibly
separating some features via user settings if needed.

* Finally rewrote the filthy, busy-looping, mouse tracking in Tracker.
The new asynchronous tracking doesn't lock the view and makes desktop
replicants happy while clicking and dragging around. Fixes #880, #7241
and certainly other tickets, that i will revisit, about refresh locks
on the desktop or mouse related bugs. Based on a reusable MessageFilter and the
recent B_MOUSE_IDLE message. Some parts are ported from the old code
and could use further simplification.

There should be no intentional user fonctional change, except:
- slightly bigger threshold radius, shorter duration thresholds
(= 1.0 x the system-wide doubleclick setting)
- not reimplemented: quickening threshold when holding shift while dragging
a pose over a destination pose.

Some parts are ported from the old code and could use further simplification.
There is one known minor regression with autoscrolling while
rect-selecting but that will be better fixed with some changes to the
autoscroll code. Will address that ASAP. As for the unknown regressions,
please test :)
