Solve a possible NPE in the Documents provider

This commit follows an internal bug report to fix a NPE that would be
thrown in specific situations on specific devices. All callers should
be able to handle the returned null value but if they don't, we can
worry about that later down the line. This null value should not be
returned under normal circumstances anyway.

libhwui: Fix a native crash with patch caching

This commit makes the system silently deal with requests to remove
patches that have already been tagged for removal instead of dumping.
The garbage collector method (PatchCache::clearGarbage) should deal
with getting rid of this patch at a later date regardless since it
has already been added to the garbage array.

Fixes AOSPA-835.

Optimize drawBitmapMesh using TRIANGLE_STRIP

Draw BitmapMesh using STRIP instead of TRIANGLES.
Depending on where the bottleneck is located in the pipeline,
there is a potential for saving two-thirds of the time spent rendering.
The speedup is due to avoiding redundant operations,
i.e., mapping each vertex four times to texture and color attribute,
sending each vertex twice to the GPU, vertex processing of GPU ...

In this patch:
1. Refactoring mesh using Strip.
2. Batch triangles by adding degenerate triangles.
3. Optimize computing positions of texture and color attribute.

Benchmark: Drawing Bitmap(1152x768 px) with 200x200 meshes
Performance is doubled (from 26.4 fps to 53 fps, Nexus10).
Memory footprint: only 17% of original method.
(from 240000 to 40401 vertices with xy, uv, rgba data.)

WiFi: Check data length before extracting

The gerrit is to check the size of input data  prior to parsing,
so that it will not lead to any crashes.

Fix problem where PhoneWindowManager waits for keyguard to draw

This fixes a problem where PhoneWindowManager times out waiting
for keyguard to draw when it's disabled.  Instead, we pass a null
token back which allows PhoneWindowManager to continue.

Fixes bug 11190932

Keyguard: We need to ensure that keyguard is showing as well to set the token

Google fix

https://github.com/SlimRoms/frameworks_base/commit/021806ec33f5f59567f3bb3af135b2a1d88c0951

fixes what it is meant to fix.

But still we need to ensure if the keyguard eg is disabled by 3rd party
apps or the keyguard is not showing due of other reasons to inform PhoneWindowManager over the token
not to wait to draw for the Keyguard and go ahead.

Fix:
Just check for isShowing in addition to the check if KeyGuard is disabled

Prevent a duplicated registration of Observers

If same Observer and same URI are registered, the callback functions are called multiple times
when data identified by a given content URI changes.
It makes system slow and it cause ANR sometimes.
And When run unregisterContentObserver(), just one deleted
but others are remained in mObservers.
So add prevent code to avoid to duplicated registraion of Observers

ActivityManagerService: Penalise large apps going to background

Large applications (PSS more than a given threshold) when closed are
penalised with higher ADJ. Now, they will be more prone to be killed by
lowmemorykiller during memory pressure levels. This ensures better app
concurrency and improved subsequent latencies as it leaves some more room
for other smaller bg apps to be alive
