Applies GRALLOC_USAGE_ALLOC_MASK to the incoming usage bits before
calling alloc on the gralloc module. This filters out the new flag
GRALLOC_USAGE_FOREIGN_BUFFERS, which is used to send a hint to the
producer, but which does not affect the allocation of buffers.

The product of width and height should be less than UINT32_MAX (in practice
smaller). Adding the checks prevents overflows when allocating buffers.

The Android EGL shim injects GL_EXT_debug_marker into the ES driver
EXTENSIONS string for the OpenGL ES 1.x and 2.0/3.0/3.1 drivers if
the extension is not already provided. This feature is used by
GLES_trace.
In Open GL ES 3.0 it became possible to query an indexed version of
the EXTENSIONS string via GetStringi(). NUM_EXTENSIONS Gets were
also added to the specification (taken from Open GL).
If the shim does not have to inject the extension, then there is no
problem, as glGetString() and glGetStringi() / NUM_EXTENSIONS will
be consistent. However, if the Android EGL shim injects the
extension, NUM_EXTENSIONS and GetStringi() will report one less
extension than is really available.
Consistency between these methods is tested by the dEQP framework
with the dEQP-GLES3.functional.state_query.string.extensions test.
If the driver does not provide GL_EXT_debug_marker, this test
fails.
This change wraps all of the affected entry points so that the
wrapped driver extensions are never visible directly to dEQP,
eliminating the inconsistency.
Early during the boot, before activity manager is ready to handle
permission checks, the system needs to be able to change the display
state. Added a hardcoded exemption for AID_SYSTEM (which already
has permission to talk to surface flinger anyhow).

In cases where SurfaceFlinger is applying a color matrix (usually for
accessibility features), we previously would perform a render-to-
texture for the initial composition, and then apply the matrix during
a copy to the framebuffer. This changes that behavior to just apply the
matrix during composition without a render-to-texture pass.
This may result in a perceived change of the image in cases with alpha
blending, since the blending is performed at a different stage of the
pipeline and the system effectively performs non-linear blends.
However, neither this nor the prior render-to-texture pass is strictly
correct in that regard, and this approach is less error-prone and
likely faster.
