Add hooks for filtering and fully rewrite rewrite selection requests and events (what existing XACE hooks cannot do), e.g. for supporting separate selection name spaces. The hook can change individual fields in the parameter struct, so operation continues with these changed values (eg. replace the original selection name atom by a different one). It's also possible to stop operations completely (with given result code) - in that case the hook needs to take care of the remaining work to do (eg. sending events) Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>
