    gl-renderer: Only check for subimage when we have extension at compile time

    If weston is compiled against a gl2ext.h that doesn't have the subimage
    extension, but then run against a gles2 library that does provide it,
    we end up disabling the glTexImage2D falback without having the subimage
    code paths compiled in.

    Add workaround for broken GL_EXT_unpack_subimage tokens

    Earlier versions of gl2ext.h defined the GL_EXT_unpack_subimage tokens
    without the _EXT suffix.  That's been fixed and we're using the _EXT
    tokens now, but just in case we're using an older, broken header, define
    the _EXT tokens manually.

    gl-renderer: Test for GL_EXT_unpack_subimage not GL_UNPACK_ROW_LENGTH

    It is defined by the mesa #include, which is just a copy of the official
    Khronos header.  It's just defined in a different section than the
    extension tokens.  In the mean time, the extension tokens were renamed
    to add a _EXT suffix (eg GL_UNPACK_ROW_LENGTH -> GL_UNPACK_ROW_LENGTH_EXT)
    and we silently failed to used the subimage extension.
