Apply a bunch of improvements to the acceleration classifier:
- When dragging from the edges, we get some delay without
movement between the DOWN and MOVE, which confounds the
classifier. Now discounts data segments where the delay
does not match the expected 16ms.
- The distance ratio did not compensate for differences
in sampling. If it does it's equivalent to the speed
ratio however. The distance ratio was removed and the
impact of the speed ratio score doubled.
- If we cannot calculate the ratio, no longer penalize
the traces for this.

Fixes a crash that happens when you turn of the screen
while moving the finger. Some touches still come in even
when the screen went to sleep. No need to get upset over
those.

Fixes bug that lead FalsingManager to be incorrect
about the screen on state.
Makes it a fatal error to query whether a touch is
falsing outside of an active session.
Prevents touch collection and logging on the locked
shade which needs no anti-falsing.

The falsing detection stopped listening for touches
when the lockscreen showed without turning the screen off.
This happens e.g. when SystemUI crashes, when switching users,
when ending lock-to-task.
As a result, the falsing detection usually got stuck on a bad
value and without further touches continued preventing all input.

DragDownHelper
Fixed couple nits, fixed a bug in DragDownHelper and in
EndPoinRatioClassifier, improved evaluation.
Change-Id: I27e9c5584f7bf0a834ac39791ee124ccc11ba0cf
Adds the possibility to store the evaluations for previous strokes and gestures.
Also and enables to take the history into account when classifying current
interatcions.
