gl-renderer: Add support for EGLDevice composited frame presentation
EGLDevice provides means to enumerate native devices, and then create
an EGL display connection from them.
Similarly, EGLOutput will provide means to access different
portions of display control hardware associated with an EGLDevice.
For instance, EGLOutputLayer represents a portion of display
control hardware that accepts an image as input and processes it
for presentation on a display device.
EGLStream implements a mechanism to communicate frame producers and
frame consumers. By attaching an EGLOutputLayer consumer to a stream,
a producer will be able to present frames on a display device.
Thus, a compositor could produce frames and feed them to an
EGLOutputLayer through an EGLStream for presentation on a display
device.
This change adds required logic to support presentation approach
described above.
Note that some unpublished EGL extensions were needed:
- EGL_NV_stream_attrib:

- EGL_EXT_stream_acquire_mode:

- EGL_NV_output_drm_flip_event:
