    gl/egl: replace gsteglimagememory with an EGLImage wrapper

    That can be passed to GstGLMemoryEGL.

    This also ports the dmabuf uploader to GstEGLImage and GstGLMemoryEGL.

    gl: implement GstGLMemoryEGL

    Because current GstEGLImageMemory does not inherit GstGLMemory, GLUpload
    allocates additional GLMemory and upload the decoded contents from the
decoder
    which uses EGLImage (e.g. gst-omx in RPi).

    This work adds GstGLMemoryEGL to avoid this overhead. Decoders allocate
    GstGLMemoryEGL and decode its contents to the EGLImage of GstGLMemoryEGL. 
And
    GLUpload uses this memory without allocation of additional textures and
blit
    operations.

    [Matthew Waters]: gst-indent the sources and fix a critical retreiving the
egl
    display from the memory.
