When there are no window layers for a display, SurfaceFlinger clears
the undefined region using GLES. Some of the places that check for
GLES composition weren't considering this special case, in particular:
- We were skipping the eglSwapBuffers() on these frames.
- We were putting VirtualDisplaySurface in HWC-only composition mode.
This change centralizes the logic for this special case.

Explicitly selects an ES 2.0 config first, then an ES 1.x config,
before attempting the fallback path for the emulator.

we add a flag to ANativeWindow::setBufferTransform that means
"apply the inverse rotation of the display this buffer is displayed
onto to".

i) SensorService dropping events. Increase SOCKET_BUFFER_SIZE in BitTube ctor.
ii) Call flush before every activate.
iii) Emulate flush for older devices. Add a trivial flush complete event when flush is called.

BitTube used to send objects one at a time and didn't
handle errors properly.
We now send all the objects in one call, which means they
have to be read as a single batch as well. This changes the
BitTube API.
Update SensorService to the new API.
Also added an API to set the size of the send buffer.

This is an attempt at improving the experience of
users with color vision impairement.
At this time this feature can only be enabled for
debugging:
adb shell service call SurfaceFlinger 1014 i32 PARAM
with PARAM:
0 : disabled
1 : protanomaly/protanopia simulation
2 : deuteranomaly/deuteranopia simulation
3 : tritanopia/tritanomaly simulation
11, 12, 13: same as above w/ attempted correction/enhancement
The enhancement algorithm tries to spread the "error"
such that tones that would otherwise appear similar can be
distinguished.

This change adds the enums for HDCP caps. An interface getCaps()
will be added later for querying whether HDCP module supports
encryption from a native buffer output from the encoder.

- this implements vec2, vec3, vec4, which are float vectors
of size 2, 3 and 4 respectively.
the code allows easy instantiation of vectors of a different
type via the tvec{2|3|4}<T> template classes.
- this also implements mat4 which is a float 4x4 matrix. the
tmat44<T> template class allows easy instantiation of a
4x4 matrix of a different value_type.
The vector types have some minimal support for the
glsl style swizzled access; for instance:
vec4 u;
vec3 v = u.xyz;
only .x, .xy, .xyz and their .stpq / .rgba equivalent are
supported.
most operators are supported on both vector and matrices:
arithmetic, unary, compound assignment and comparison
(bit-wise operators NOT supported).
- operations available on vectors include:
dot, length, distance, normalize and cross
- operations available on matrices include:
transpose, inverse, trace
- and a few utilities to create matrices:
ortho, frustum, lookAt

SF can spawn threads (indirectly) during initialization
and we want those to be spawned at URGENT_DISPLAY_PRIORITY
(in theory they should set their own, but some code lives
in vendor libraries and doesn't).

EGL now picks the buffer format out of a small set
of formats compatible with CPU consumers instead of
using the EGL_NATIVE_VISUAL_ID.
