6f0871222f 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.

8fb47ec10e Fix Android's glEGLImageTargetRenderbufferOES() wrapper
glEGLImageTargetRenderbufferOES() pass the wrapped EGLImage
to the implementation, rather than the unwrapped one.

673d2dbaae Use the TLS register if HAVE_ARM_TLS_REGISTER is defined
this will be needed for SMP, but would improve dispatching GL calls a bit
on armv6 and above.

618fa10949 fix [2187212] add support for GLESv2 dispatch based on TLS
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.

[Pending Dr No approval for MR1]
