Keep OverScroller.SplineOverScroller state consistent.
Currently update() bails out early if it is called
too soon after mStartTime has been set. In this case
mCurrentPosition remains holding an obsolete value
from a previous animation. This causes some strange
behavior (see the referenced bug).
This patch makes sure that mCurrentPosition is
updated every time that mStart is updated.

Fix huge bounce-back in ListView when double-flinging
The bounce-back reliably happened when AbsListView.fling
was called with high enough velocity (>50000). Such values
caused integer overflow when squared in the course of some
ballistic calculations in OverScroller.fitOnBounceCurve.

Don't update OverScroller fling state if no time has passed since start
If no time has passed when we try to update fling state, skip the
update computation since there is nothing to do.
Fixes a bug where we could return NaN from
OverScroller#getCurrentVelocity.

Switch from FloatMath -> Math and Math.hypot where possible
The motivation is an API change: FloatMath is going to be
deprecated and/or removed. Performance is not the goal of
this change.
That said...
Math is faster than FloatMath with AOT compilation.
While making the change, occurances of:
{Float}Math.sqrt(x * x + y * y) and
{Float}Math.sqrt({Float}Math.pow(x, 2) + {Float}Math.pow(y, 2))
have been replaced with:
{(float)} Math.hypot(x, y)
Right now there is no runtime intrinsic for hypot so is not faster
in all cases for AOT compilation:
Math.sqrt(x * x + y * y) is faster than Math.hypot(x, y) with
AOT, but all other combinations of FloatMath, use of pow() etc.
are slower than hypot().
hypot() has the advantage of being self documenting and
could be optimized in future. None of the behavior differences
around NaN and rounding appear to be important for the cases
looked at: they all assume results and arguments are in range
and usually the results are cast to float.
Different implementations measured on hammerhead / L:

Fix janky programmatic ListView scrolling
Adjust AbsListView to use a linear interpolator for smooth scrolling
rather than the default scroller behavior. This prevents irregular
motion as the scroll is altered in-flight to account for varying

Can't stop the fling!
Bug: 5335420
Fixed a bug in VelocityTracker where the output velocity was
not being set to zero when not available.
Added a condition to ensure that the velocity is at least
the minimum fling velocity before continuing. If not, then
the user is trying to stop the fling and scroll more precisely.

Make EdgeEffect public API.
This enables apps to make use of the system's visual edge effect used
during overscroll in 2D content.
Also un-@hide the getCurrVelocity methods from Scroller/OverScroller,
without which it becomes cumbersome to obtain values to pass to the
EdgeEffect#onAbsorb method.

Modified OverScroller curves
When OverFlinged, the scroller goes back to the edge using a spline
instead of a parabolic curve. This ensures that the final velocity of
this movement is null, thus removing the visual discontinuity that can
be observed with the current version.
Bouncing coefficient is deprecated. Changed doc accordingly.
New more expressive spline tension tuning coefficients.
These were tuned to match the one used before the refactoring of CL 81532.
