On some Mac drivers with shader version 4.1, they will
treat unused std140 and shared uniform blocks' members as inactive. However,
WebGL2.0 based on OpenGL ES3.0.4 requires all members of a named uniform block
declared with a shared or std140 layout qualifier to be considered active.
The uniform block itself is also considered active.
This workaround is to reference all members of unused std140 and shared uniform blocks
at the beginning of the vertex/fragment shader's main().

After experiencing a device loss, Renderer11::resetDevice can fail to
recreate mDevice, leaving it null. In a following call to
testDeviceLost, mDevice will be dereferenced, causing a segfault.

When ANGLE is using D3D11 and not using DirectComposition, DXGI will hook
the window's message loop and override Alt+Enter to trigger a transition
to exclusive fullscreen mode. This disables that behaviour, since it's
inconsistent between backends and, at least during my testing, the
application did not even work correctly after the transition to fullscreen
mode.
This commit should be similar to the workarounds implemented in Qt and mpv
to prevent this behaviour and will hopefully make those workarounds
unnecessary. Only the DXGI_MWA_NO_ALT_ENTER flag is used, since the other
flags didn't seem to have an effect and probably only matter in fullscreen
mode.

In the CopyNativeVertexData template function, in the else clause
use memcpy/memset rather than for loops. This is a performance
improvment for floating point versions of CopyNativeVertexData,
particularly on 32-bit Firefox, where the -arch:IA32 compiler
option used cause the compiler to generate fld/fstp operations
inside the for loops.

The solution is the same as in GYP version:
1. Check if .git/index is available in angle directory.
2. Use generated commit.h file if git is available or copy the default

That way RenderbufferStorageMultisample accepts STENCIL_INDEX8 as
an internal format for a multisampled buffer (samples > 0) as it
isn't concerned by the restriction on integer component types anymore.
This is consistent with the component type returned by the NVIDIA driver.

vsnprintf is defined in stdio.h according to the standard. It was not in
the include chain of angleutils.cpp, which broke the build on Linux on
some configurations. Seems like other toolchains include the function in
some non-standard way.

Description of the algorithm:
http://code.google.com/p/mvujovic/wiki/ShaderControlFlowAnalysis
This flag is one potential solution to timing attacks on textures containing cross-domain content
or user agent data.
This kind of analysis could be useful for both WebGL and CSS Shaders.
The SH_TIMING_RESTRICTIONS flag will reject a shader if it uses texture dependent data to affect
control flow.
Other ways of affecting shader timing such as using NaNs in basic arithmetic operations or using
built-in functions (e.g. atan) with different inputs are still under investigation.
