Fix texture corruption
When memory gets low on a device, activities flush everything they can.
Hardware-accelerated activites, such as Launcher, flush GL resources and destroy
the GL context. However, some resources were still hanging around, due to deferred
destruction policies (we don't delete layers until the DisplayLists they are in
are finalized, to ensure we don't deref deleted objects). This meant that we were
referring to obsolete GL data in these objects. in particular, it meant that we might
come around later, after a new GL context was created, and delete a texture object
that was incorrect. We use the layer's "texture id" to refer to the texture underlying the
layer. But if there's a new GL context, then this texture ID is no longer valid, and
we may be deleting the texture that a different object (layer, icon, whatever) is referring
to, because the driver may return that same ID under the new GL context.
The fix is to more aggressively delete things that we know will not be used again
when the GL context is destroyed. In particular, we delete all resources being used
by all DisplayLists at GL context destruction time.

Skip eglSwapBuffers() call when we do not draw to GL
The fix is to track when we issue GL drawing commands, and to skip the
call to eglSwapBuffers() when a DisplayList does not result in
any actual rendering calls to GL.

Optimization of alpha with DisplayList properties
Some views (such as ImageView and TextView) handle non-opaque alpha
values directly. This was originally an optimization, but we can handle it faster
in many cases without this optimization when DisplayList properties are enabled.
Basically, if a view has non-overlapping rendering, we set the alpha value directly
on the renderer (the equivalent of setting it on the Paint object) and draw each
primitive with that alpha value. Doing it this way avoids re-creating DisplayLists
while getting the same speedup that onSetAlpha() used to get pre-DisplayList properties.

Re-enable DisplayList properties.
Re-enabling DisplayList properties last week caused some app
errors due to the way that some transforms were being handled (specifically,
those coming from the old Animations and ViewGroup's childStaticTransformation
field). This change pushes *all* transform/alpha data from View.draw() into
the view's DisplayList, making DisplayLists more encapsulated (and correct).

Use a status_t return type for GL functors
WebView needs more fine-grained control over the behavior of the
framework upon execution of the display lists. The new status_t
allows WebView to requests its functor to be re-executed directly
without causing a redraw of the entire hierarchy.

Handle view properties at the native level
Basic functionality of handling View properties (transforms,
left/right/top/bottom, and alpha) at the native DisplayList level.
This logic is disabled for now (via compile-time flags in View.java and
DisplayListRenderer.h) as we continue work on it (there is no advantage
to the new approach until we optimize invalidation and rendering paths
to use the new code path).

Record possible clip rejects when recording display lists
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.

Sub display list in TextView
TextView uses a sub-display list to 'cache' the rendering of its
text. This saves time when drawing an editable text, where the blinking
cursor forces a re-draw twice per second, which creates pauses during
scrolling.
Added a sub-display list invalidation when an appearance span is
modified/added/removed.
Also added an invalidation of the display list when selection range
is changed.

Decouple GLES20RecordingCanvas lifetime from GLES20DisplayList.
Bug: 5062011
Previously, each GLES20DisplayList would hold onto an instance of
GLES20RecordingCanvas. In turn, each GLES20RecordingCanvas
held onto an SkWriter with a 16Kb buffer along with several other
objects. With one display list per view and hundreds of views,
the overhead could add up to a few megabytes.
Ensured that the GLES20RecordingCanvas is reset as soon as
the display list has been constructed, thereby promptly freeing
the 16Kb buffer.
Changed GLES20DisplayList so that it acquires a GLES20RecordingCanvas
from a pool as needed and recycles it when done.
Removed some dead code and cruft related to the construction of
GLES20Canvas objects in general. Some code was written with the
assumption that the underlying renderer object could change
behind the scenes or might be lazily constructed, but that isn't
actually the case so we can simplify things.
Removed an unnecessary weak reference from GLES20DisplayList
to the View. It isn't actually used anywhere.
Fixed a bug in GLES20DisplayList where isValid() would return
true while the display list was being recorded. This is incorrect
because the native display list might not actually exist. Worse,
even if the native display list does exist, it is stale and
potentially refers to old Bitmaps that have been GC'd (because the
mBitmaps list was cleared when recording started).

Use optimized display lists for all hwaccelerated rendering
Previously, display lists were used only if hardware acceleration
was enabled for an application (hardwareAccelerated=true) *and* if
setDrawingCacheEnabled(true) was called. This change makes the framework
use display lists for all views in an application if hardware acceleration
is enabled.
In addition, display list renderering has been optimized so that
any view's recreation of its own display list (which is necessary whenever
the visuals of that view change) will not cause any other display list
in its parent hierarchy to change. Instead, when there are any visual
changes in the hierarchy, only those views which need to have new
display list content will recreate their display lists.
This optimization works by caching display list references in each
parent display list (so the container of some child will refer to its
child's display list by a reference to the child's display list). Then when
a view needs to recreate its display list, it will do so inside the same
display list object. This will cause the content to get refreshed, but not
the reference to that content. Then when the view hierarchy is redrawn,
it will automatically pick up the new content from the old reference.
This optimization will not necessarily improve performance when applications
need to update the entire view hierarchy or redraw the entire screen, but it does
show significant improvements when redrawing only a portion of the screen,
especially when the regions that are not refreshed are complex and time-
consuming to redraw.

Reuse display lists at the java level.
Objects are invalidated and reset instead of being nulled out
and recreated. This avoids creating small amounts of garbage for
the display list and canvas objects.
