This change makes GLConsumer use the EGL_ANDROID_image_crop extension when
available on a device. The crop rectangle is passed to the EGL driver when
creating EGLImages, allowing the crop to be performed by the driver rather than
using the texture transform matrix.

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.

If the implementation eglCreateContext failed, we called
eglGetError(), so we could check that it set the EGL error properly.
But since we'd already called this, when the app called eglGetError()
it would get EGL_SUCCESS!

We've had the extended behavior since Android 4.3, but the extension
hadn't been ratified by Khronos yet so we couldn't add it to the
extension string.

If there are two or more buffers pending that are ready for
immediate presentation, drop all but the last one.
Any code that didn't explicitly specify timestamps for buffers
was using the default value (auto-generated "now"). As a result,
surfaceflinger would drop frames whenever more than one buffer
was queued. We now use zero as the auto-generated timestamp,
and we don't set the timestamp in eglBeginFrame().

The EGL 1.4 spec section 3.5.1 states that EGL_BAD_ALLOC should be set
if the supplied window already has an associated EGLSurface, not
EGL_BAD_NATIVE_WINDOW as is currently set.

This allows apps to find OpenGL ES 3.0 functions using
eglGetProcAddress() instead of dlopen/dlsym.

in the common case this saves one instructions per jump
(which will help with the i-cache).
this change also gets rid of the "use slow tls" option,
which was useless. So at least now architectures that don't have
assembly bindings will perform much better.

destroyed but current-to-a-thread resources are only destroyed
when they're made not-current; however, we were not destroying
those when the thread itself terminated, causing these resources
to be leaked forever.
we now install a tls-key destructor that takes care of this
by calling eglReleaseThread upon thread termination.

eglCreateSyncKHR requires a call to glFlush which we were not doing.
fixed by moving the code above eglSwapBuffers(), which both
fixes the problem and gives us a slightly better idea of when
the GPU is done drawing.

We now detect at runtime which sync features to use, which
allows us to remove a lot of the compile-time configuration
options. There is still one option though, to disable
KHR_fence_sync on some devices (which are more efficient
without it).
- added a backdoor to get the vendor's EGL strings
the new logic is:
- use always ANDROID_native_fence_sync if available
- fallback to KHR_fence_sync if available and not disabled
by the compile-time option
- use KHR_wait_sync if available and either of the above is
enabled

- move all the code related to EGL extensions in one place
- add missing extension strings:
EGL_KHR_lock_surface
EGL_KHR_reusable_sync
- add public extensions strings and entry-points
EGL_ANDROID_wait_sync
EGL_ANDROID_presentation_time
- add missing entry-points for EGL_KHR_reusable_sync

Also, fix JNI encoding of "long" in glgen.

Since ES3 is backwards compatible with ES2, a new wrapper isn't
necessary, and the Khronos implementation guidelines recommend
supporting both versions with the same library.

Gfx-3d: fix GetProcAddress in egl extention
This patch can fix issue when Proc address return NULL.
Glbench10, egl-ext and conformance test need this patch to run pass.

Currently, to activate OpenGL tracing, an application has to be
start with --opengl-trace option (or have a debug prop set).
This CL adds support for tracing an application which may already
be running. This is implemented as follows:
- DDMS initiates a JDWP message to the VM indicating that
opengl traces be enabled.
- When that message is received, a flag is set that indicates
that tracing should be enabled.
- The trace flag is checked during every eglSwap() operation,
and if it finds that tracing should be active and it isn't,
then it starts the tracing component.

This change adds support for the EGL_ANDROID_native_fence_sync extension to the
Android EGL layer. It also fixes a couple minor issues with the extension spec.

If the EGL implementation supports the EGL_IMG_hibernate_process
extension, use it to hibernate (and hopefully release memory or other
resources) when the process isn't actively using EGL or OpenGL ES. The
idleness heuristic used in this change is:
(a) Wake up when entering any EGL API call, and remain awake for the
duration of the call.
(b) Do not hibernate when any window surface exists; this means the
application is very likely in the foreground.
(c) Do not hibernate while any context is made current to a thread.
The app may be using a client API without the EGL layer knowing,
so it is not safe to hibernate.
(d) Only check these conditions and attempt to hibernate after a
window surface is destroyed or a thread's context is detached. By
not attempting to hibernate at the end of every EGL call, we avoid
some transient wakeups/hibernate cycles when the app is mostly idle,
or is starting to become active but hasn't created its window
surface yet.
On a Galaxy Nexus, hibernating frees 1567 VM pages from the process.
Both hibernating and waking can take anywhere from 30ms to over 100ms
-- measurements have been very inconsistent.

This is in preparation for a change that will hibernate the underlying
EGL when idle. Instead of a bare egl_display_t*, get_display() now
returns a egl_display_ptr, which acts like a smart pointer. The
"wakecount" counter managed by the smart pointer isn't used for
anything in this change. It will be used to make sure we don't
hibernate when any thread is in an EGL call, without having to hold a
mutex for the duration of the call.

This change adds a debug option to EGL to use an EGLSyncKHR each frame to
determine when the GPU finishes rendering the frame.
