On android, android's nsWindow creates LayerManaer only in nsWindow::Create(). When WebRender error happened, gecko just stopped rendering by disabling Webrender.
The nsWindow needs to re-create LayerManager during disabling Webrender. Further, during disabling WebRender, All GeckoSurfaceTextures should not be attached to GLContext. It is for preventing a conflict with AttachToGLContext() call in SurfaceTextureHost::EnsureAttached().

GeckoSurfaceTexture could bind to only one GL context at once. With WebRender, GeckoSurfaceTexture is soon bounded to sharedGL on render thread. It caused the problem if GeckoSurfaceTexture is rendered to WebGL. It could happen only for video's GeckoSurfaceTexture. To avoid the problem, the GeckoSurfaceTexture is bound to gl context when it is actually rendered on WebRender.

During playing a video, one GeckoSurfaceTexture is used for all RenderAndroidSurfaceTextureHostOGLs of the video. GeckoSurfaceTexture owns multiple buffers. UpdateTexImage() needs to be called at the correct timing for adjusting SurfaceTexture's buffer status.

When mContinuousUpdate is true, UpdateTexImage() needs to be called for each rendering.

When SurfaceTexture is single buffer mode, UpdateTexImage() should be called only once for each publish. If UpdateTexImage() is called more than once, it causes hand on puglish side.

Splitting part of OGLShaderProgram.h out into OGLShaderConfig.h makes it
easier to keep GLContext.h included in OGLShaderProgram.h for inlining
purposes.
