Ensure memory ordering around libagl and EGL refcount operations
The android_atomic_inc/android_atomic_dec functions don't impose
sufficient memory ordering. Using them for object refcounting could
allow an object to be destroyed prior to writes by a different thread
being visible.

EGL: Ensure surfaces are disconnected when destroyed
When eglDestroySurface is called, remove all references to the surface
in all contexts. This ensures that the surface is disconnected
immediately.

Fix EGL shim extension injection for GL ES 3 drivers.
The Android EGL shim injects GL_EXT_debug_marker into the ES driver
EXTENSIONS string for the OpenGL ES 1.x and 2.0/3.0/3.1 drivers if
the extension is not already provided. This feature is used by
GLES_trace.
In Open GL ES 3.0 it became possible to query an indexed version of
the EXTENSIONS string via GetStringi(). NUM_EXTENSIONS Gets were
also added to the specification (taken from Open GL).
If the shim does not have to inject the extension, then there is no
problem, as glGetString() and glGetStringi() / NUM_EXTENSIONS will
be consistent. However, if the Android EGL shim injects the
extension, NUM_EXTENSIONS and GetStringi() will report one less
extension than is really available.
Consistency between these methods is tested by the dEQP framework
with the dEQP-GLES3.functional.state_query.string.extensions test.
If the driver does not provide GL_EXT_debug_marker, this test
fails.
This change wraps all of the affected entry points so that the
wrapped driver extensions are never visible directly to dEQP,
eliminating the inconsistency.

Add ES3 support to libGLESv2 and tracing tools
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.

Hibernate the EGL implementation when idle
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.

Increment/decrement a counter around EGL calls
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.

Don't wrap EGLImageKHR and EGLSyncKHR anymore
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.

remove multiplexing of multiple EGL implementation
from now on, the system can only have one EGL
implementation. this means the software and h/w renderer
cannot be used at the same time on a device. Of course, the
h/w renderer is always prefered; in its absence we
default to the software renderer.

add support for GL_EXT_debug_marker
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.

fix crash when validating an invalid EGL objects
the code that validated EGL objects dereferenced the object
to access its EGLDisplay -- needed for validation (!).
This was wrong for two reasons, first we dereferenced the object
before validating it (potentially leading to a crash), secondly
we didn't validate that the object existed in the right EGLDisplay.
We now use the EGLDisplay passed by the user API.

EGL: move disconnect to surface dtor
This change moves the call to native_window_api_disconnect from
eglDestroySurface to the egl_surface_t destructor. The egl_surface_t
can outlive the external EGLSurface if eglDestroySurface is called while
the surface is made current on a thread.
