music search disabled.

Allow override of DUN settings

Allow override of system DUN settings by setting
persist.sys.dun.override
to one of the following values:
2 = not set, 0 = DUN not required, 1 = DUN required
If the prop is not set or is set to an invalid value the system setting

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.)

Frameworks: add all slim shortcut image resources

Importing for now the old one from KitKat. Graphics group is currently
vectorizing and revamping all. When they are finished we overwrite them and
add xxxhdpi ones as well.

Doing this now due that it is stopping the progress on a bunch of features right now

And a small method renaming to be inline with the other methods
