These were originally needed because the official android.support classes
required APIs that we didn't support and it didn't seem worth the effort
to make them happy when the actual apps using these compat classes
were comparatively trivial.
We now support all the necessary APIs, so we can remove the overrides
and let the apps use their bundled android.support classes.
Now that we have a reasonably well working SurfaceView implementation,
it is actually cleaner to just implement GLSurfaceView the way AOSP
does. In fact, their code doesn't have any weird dependencies, and
can mostly be used as-is.
The AOSP code is pure Java, which means we had to implement some
EGL wrappers.
This change fixes issues with Wayland (it only ever worked because
the pbuffers were allocated using an XWayland EGLDisplay), and
with resizing (which we simply didn't support), all while getting
rid of quite some (arguably not very readable) LoC.
The current implementation requires a VA-API driver and a Wayland
compositor with YUV-buffer support. GNOME supports YUV-buffers
since the recent version 45 release
