    configure.ac: Let's enable the AM_MAINTAINER_MODE.
    
    Otherwise, Make will not invoke autoconf even if the configure.ac
    changed.

    For DRI swap buffers.
    
    This commit added two APIs to support the DRI swap buffer.
    one is glamor_egl_exchange_buffers() which can swap two
    pixmaps' underlying KHRimages/fbos/texs. The DDX layer should
    exchange the DRM bos to make them consistent to each other.
    
    Another API is glamor_egl_create_textured_screen_ext(), which
    extent one more parameters to track the DDX layer's back pixmap
    pointer. This is for the triple buffer support. When using triple
    buffer, the DDX layer will keep a back pixmap rather then the
    front pixmap and the pixmap used by the DRI2 client. And during
    the closing screen stage, we have to dereference all the back
    pixmap's glamor resources. Thus we have to extent this API to
    register it when create new screen.

    glamor_copyarea: Don't use GL_CLAMP_TO_BORDER when GLES2 enabled.
    
    We may need to modify all the shader to handle GL_CLAMP_TO_BORDER
    when using GLES2. XXX, for now, we just ignore them.
