258385978c 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.

b29e5e8c26 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.

This change adds a debug option to EGL to use an EGLSyncKHR each frame to

50129e4ae2 gltrace: Send vertex attribute data after glDraw() call.
This patch enables tracing of vertex attribute data that
is specified using glVertexAttribPointer().

At the time the glVertexAttribPointer() call is made, we
only receive a pointer in client space, without any indication
of the size (# of attributes). This size is known only at
the time of the glDraw() call.

This patch generates a new message glVertexAttribPointerData()
when a draw call is issued that contains the vertex attribute
data.

A glDrawArrays() call directly gives the size of data to copy.
A glDrawElements() call gives the indices to copy. In such a
case, all data between the min & max indices drawn are copied
and sent to the host. To support glDrawElements() with an
element array buffer, this patch also adds state that maintains
a copy of all element array buffers.

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.

fb87e54a9a 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.

The extension itself will be handled by GLES_trace (eventually),

If the h/w implementation has this extension, we'll call that version
instead of our dummy version.

3f194e6e3a gltrace: add user settings to control data captured.
Currently users do not have control over the amount of data
captured during tracing. This patch adds 3 settings that users
can enable/disable at runtime:
  - capture framebuffer on eglSwap() calls
  - capture framebuffer on glDraw*() calls
  - capture texture data passed to glTexImage*() calls
Disabling these options when not needed signficantly decreases
the size of the trace file, and reduces performance overhead for
the running application.

These settings are stored in the per process GLTraceState.
A separate thread listens for commands from the host, and updates
the state based on the user commands.
