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.

Disable EGL hibernation due to jank
Hibernating EGL takes a long time (>100 ms) and blocks all other
rendering. During window animations, the outgoing activity begins
hibernation before the animation stops, causing visible stutter.
Hibernation is still available by setting 'BOARD_ALLOW_EGL_HIBERNATION
:= true' in the devices BoardConfig.mk

Fix deadlock when cleaning objects in eglTerminate
When eglTerminate() is called with a window surface still exists, a
deadlock would occur since egl_display_t::terminate() holds a lock
while destroying the window surface, which calls
onWindowSurfaceDestroyed() which attempts to take the same lock.
This change refactors the hibernation code and data into a separate
object with its own lock, separate from the egl_display_t lock. This
avoids the deadlock and better encapsulates the hibernation logic.
The change also fixes a bug discovered incidentally while debugging:
hibernating after calling eglTerminate() succeeds, but will cause
awakens from subsequent eglInitialize() to fail. We will no longer
hibernate a terminated display.

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.

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.

fix a dead-lock in eglMakeCurrent
this was introduced in a recent change. eglMakeCurrent can
end up calling eglDestroyImageKHR via ANativewWindow::disconnect
when the consumer is in the same process.

fix a race condition in eglMakeCurrent()
it would happen when a context was made non-current, in this
case we would call the implementation's eglMakeCurrent() which
would succeed, if we're rescheduled at that point, another
eglMakeCurrent() could make that context current to another thread,
however, when we came back to the original call we would
overwrite egl_context_t internal state.
this is fixed by moving the critical section under
egl_display_t's lock.

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.
