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.

This optimization allows us to quickly skip operations that lie
entirely outside of the known bounds of a display list. Because
of ViewGroup.setClipChildren, we must keep the operations recorded
in the display list. setClipChildren(false) is however a very
uncommon operation and we will therefore often benefit from this
new optimization.

There are occasional races during application shut down where the
input dispatcher will close an input channel before the application
has finished its last event. So just ignore EPIPE.
Also tweak the logging for failed input event injection to make
it clearer which pid was trying to perform the injection.

Change clock sync control to velicity form PI loop. Tuned for office LAN and
WiFi conditions, will probably perform better in clean environments.
Improve packet filtering to prevent clock sync on bad rtt.
Changed diag interface to take rtt times, P, I, D are no longer supported.

Monotype has released a new version of DroidNaskh. This version
has *no* changes in any of the glyphs. The change is to remove
the following tables from the .ttf files. These tables are not
used by Android and are not included in any of our other Droid
font files. These tables are not part of the TrueType Font file
specification. Removing these tables reduces the size of the
font files from ~370K to ~93K. Monotype did not bump the version
because there were no user visible changes.
ASCP and TSI0 through TSI5

Set a barrier on traversals.
Vsync is still not enabled by default in this patch so there
should be no observable effect from these changes.
