    egl/x11: hack for context transfers

    There is a better approach to this in the winsys-handle branch, but
    for now avoid using transfers at all by always allocating our own
    backing store directly.

    glx: permit building with older protocol headers

    I'd like to be able to build mesa on current distro releases without
    having to upgrade from the standard dri2proto and glproto headers.  With
    this change I'm able to build on ancient releases such as Ubuntu 9-10...

    In general, it would be nice to be able to build-test mesa to check for
    unintended breakages without having to follow the external dependencies
    of every group working on the codebase.
