Improve scrolling cache

Scrolling cache helps make short scrolls/flings smooth but will
cause stutter when long flings are made. This patch disables
scrolling cache when long flings are made.

This patch also fixes a related bug where scrolling cache will
not be enabled properly when transitioning from flinging to scrolling.

Patch Set 2: Calculate threshold based on maximum velocity (Sang Tae Park)

Delete media tests

Media files take up a lot of spce. Deleting them cuts the size of frameworks
almost in half.

Scroll: modified velocitytracker

Velocitytracker and overscroll are called on every touch event to
calculate if there is a scrolling/fling. Move this and the recycling
to static voids so they are pre-optimized at compile time rather than
after evoking the method call during runtime (JIT) to increase responsiveness.
