New, less blue overscroll assets with tuned constants in EdgeEffect class.
Glow absorb animation was very slow with high velocity flings. Clamped the velocity
and adjusted constants for start values and duration of absorb animation.

Optimize invalidate calls in lists.
AbsListView was doing too many invalidates during scrolls/flings.
Some of them were also covering too large an area of the screen.

Add transient state tracking to Views
Transient state is temporary bookkeeping that Views need to perform
that the app should not need to be aware of. Examples include text
selection regions and animation state.
Transient state is a problem for AdapterViews like ListView that do
view recycling. Unless the app takes responsibility for tracking and
restoring transient state as if it were a part of the adapter's data
set, it cannot correctly recycle views. Selections disappear when an
EditText is scrolled out of sight and animations seem to play on the
wrong views.
Views can now flag themselves as having transient state. (As the name
implies, this should be a temporary condition.) If a ViewGroup
contains a child with transient state, that ViewGroup also has
transient state.
AbsListView's recycler now tracks views with transient state
separately. Views with transient state will be retained, and until a
data set change occurs the same view will be reused for that position
instead of calling the adapter's getView() method.
The API to set and check transient state is currently hidden.

Localized optimizations in views and bitmaps
* Don't call context.getResources() redundantly when unnecessary;
similarly for Resources.getCompatibilityInfo()
* During bitmap creation, don't bother clearing to 0: it's unnecessary
because now that the raw bits are stored in a VM-side byte array, it
was cleared at initialization time. Also, don't use the sanity-
checking public entry point to erase to a color, because we know
that we're by definition in a "legal" path to erase to the initial
contents and don't need to incur the overhead of the (inappropriate)
sanity checking.

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.
