    Bug #16430: Ignore ConfigureNotify on non-root windows in
    UpdateConfiguration

commit 332eee90c4d00be3b11049e0261323abe89a96dc

    Rename parameters to clarify QueryVersion/QueryExtension.

    These parameters are not treated as input. Rename them to make
    the inner workings slightly more obvious.

commit 824f3d4a3a4669526a5c391c6668df0384b49cdb

    Bug #14388: Remove XRRScreenConfig() and XRRConfig() from Xrandr.h.

    It seems that they were never actually implemented.
    Also remove the corresponding manpage symlinks.

commit 23a47035818390ca197179a9a69a54badb370990

    Hide some private symbols.

    XExtensionInfo, XRRExtensionName, XRRFindDisplay, _XRRHasRates and
    _XRRVersionHandler are internal to libXrandr.  Don't export them.
