Dejank electron beam.
Don't process UEvents in Dalvik unless they match a pattern.
On some devices, vsync is delivered from the kernel to userspace
over a netlink socket via UEvent. The result is that a thread wakes
up, reads a message, creates a new String then searches it for matches
against a pattern on every single frame.
Reduce the overhead by performing the initial pattern matching in
native code.

The AudioService now tracks the shutter sound enforcement status, in
addition to the existing approach. Check with it when doing shutter
sound operations.

The failures were caused by the implementation of doTextRunCursor
passing a too-small value for contextCount into the underlying
getTextRunAdvances call (it wasn't accounting for the start offset).
Thus, when getTextRunAdvances made a copy of the text for its cache key,
it was getting a partial copy.
This patch fixes the size so the cache key always has a full copy of the
text.

This fixes bug 6948776
android.graphics.cts.PaintFlagsDrawFilterTest#testPaintFlagsDrawFilter
failures on JO
When we moved the drawing of text decorations (underline, strikethrough)
from Skia to our own drawing (so we could take into account the metrics
computed by TextLayoutEngine), we just used the raw flags from the
paint, which ignored the overrides that a DrawFilter can effect.
The patch simply checks for the existence of a DrawFilter in the canvas,
and applies it to a copy of the paint where present. This will be one
extra paint copy where the filter exists, but that's expected to be rare
(other than running this CTS test, of course).

This bug was triggered by user code concurrently mutating the character
array while calling into a drawText method in another thread. When the
value of the array changed, it caused inconsistent state, leading to
assert failures.
This is arguably bad behavior by the user code, but it shouldn't cause a
native crash. The fix is to do a defensive copy of the text into the
key, so the value is guaranteed to remain constant throughout the text
layout process. The change is mostly deletion of code, because there was
an optimization to try to avoid such a copy. That optimization was not
actually effective, however, because the indexOfKey() operation in the
KeyedVector underlying the TextLayoutCache did the copy anyway. Thus,
even though this change looks like it's introducing a copy where there
wasn't one before, the actual performance impact should be nil.
Note that the ability to handle a mutating argument is now part of the
contract for TextLayoutEngine::getValue(), and is now documented. That
contract may change, as the result of future optimization. Also, care
was taken to only use the value after the copy.
Other performance issues with TextLayoutCache are tracked in bug
7271109.

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.
