This change has been made in Khronos SVN for GLES2 already, however it
is mildly controversial and discussion is on-going.
This change is necessary for Android because otherwise applications
cannot include both GLES2/gl2.h and GLES3/gl3.h as the glShaderSource()
prototype mismatches. Native programs may include framework headers
(which now include GLES3 headers only) but already have included GLES2
headers, creating an incompatibility.

The shell property debug.egl.trace can now be set to:
0
disables tracing
1
logs all GL calls
error
checks glGetError after every GL call, logs a stack trace on error
systrace
logs each GL call to systrace

this simplify our EGL wrapper implementation a lot.
This wrapping is no longer needed now that we can only
support a single underlaying EGL implementation.

This extension is always added to the GL_EXTENSIONS
extension string for the current GL context, regardless
of if it's supported by the h/w driver.
The extension itself will be handled by GLES_trace (eventually),
when GLES_trace is not enabled, it'll result to a no-op.
If the h/w implementation has this extension, we'll call that version
instead of our dummy version.

* commit '4eb1ad5e98c7b36f7ac4ec8c3270f9763afd107e':
better fix for [3028370] GL get error should return a valid error if no context is bound.
it turns out that we cannot return INVALID_OPERATION from glGetError() because the
GL spec says that it must be called in a loop until it returns GL_NO_ERROR.
now, we always return 0 from GL functions called from a thread with no
context bound. This means that glGetError() will return NO_ERROR in this case,
which is better than returning a random value (which could trap the app in a loop).
if this happens in the main thread of a process, we LOG an error message once.

glEGLImageTargetRenderbufferOES() pass the wrapped EGLImage
to the implementation, rather than the unwrapped one.

Instead of using a different function pointer table for ES 1.x and ES 2.x,
we use a single one that is the union (sort|uniq) of both tables. Two
instances of this table are initialized with pointers to GL ES 1.x and GL ES 2.x
entry-points.
When a context is created, we store its version number and when it is bound to a
thread we set the approruiate table based on the stored version.
This introduce no penalty while dispatching gl calls to the right API version.
