glx/apple: locate dispatch table functions to wrap by name
Avoid reaching into the dispatch table internals (and thus having to deal with the complexities of remap etc.) by identifying functions to wrap by name. See: https://lists.freedesktop.org/archives/mesa-dev/2015-June/086721.html et seq. https://bugs.freedesktop.org/show_bug.cgi?id=90311 Signed-off-by: Jon Turney <[email protected]> Reviewed-by: Emil Velikov <[email protected]>
