an empty list terminated with EGL_NONE.

Build software AGL library with correct get_tls() macro for ARMv7 based platforms
Fix glReadPixels() to verify that both x and y are non-negative.
We believe these errors happen when the window
manager has told surface flinger to close the
native window.
If this error happens while we are creating the
EGL surface we exit the render loop (and
therefore exit the render thread.)
If the error happens while swapping the surface
we ignore it.
In either situation, we expect that the
application is about to be shut down by the
window manager, so it should not be necessary
to try and recover from the error.
glEGLImageTargetRenderbufferOES() pass the wrapped EGLImage
to the implementation, rather than the unwrapped one.

with the GLThread.
We used to just set the mPaused state and return,
now we wait until the rendering thread signals
that it has noticed the change in pause state.
This makes Pause/Resume more consistent with
other UI-thread-to-GLThread event communication.
This change was made in the hope of fixing some
race conditions observed in monkey testing.
We now release the EGL context when pausing. This
is required to reduce the chance of running out of
contexts on devices which support a limited number
of active EGL contexts.
Someday we may implement a global EGL context
manager that will allow us to let EGL contexts
persist until another activity needs an EGL
context. But for now, without such a manager,
we take the conservative approach.
Separately, we now terminate EGL when
pausing on Sapphire. This is a requirement of the
Sapphire OpenGL driver.
Previously we imlpemented the standard semantics for
eglInitialize / eglTerminate, which are that
eglInitialize may be called any number of times,
but the first call to eglTerminate will terminate
the display.
Now we follow reference-countins semantics, which
means that eglTerminate will only terminate the
display when the reference count returns to zero.
This change allows EGL to be used by multiple
independently written modules in the same process.
(Otherwise there is no way for the independent
modules to coordinate their use of the display.)
We now distinguish EGL_CONTEXT_LOST errors from
other kinds of errors. We return "true" if
the swap completes successfully, "false" if
the swap fails due to EGL_CONTEXT_LOST, and
throw a RuntimeException if the swap fails due
to any other cause.
If eglSwapBuffers succeeds, we now avoid calling
eglGetError at all, which means we avoid clearing
any EGL errors that might already have been
pending before eglSwapBuffers is called.
