r10537: - we now use a much nicer way to handle talloc_free(timed_event)
the events code replaces a destructor to one that returns allways -1 while it's calling the event handler - we don't need the composite and winsrepl specific fixes any more - this also fixes the problem with smbcli, dcerpc, cldap, ldap and nbt request timeouts metze (This used to be commit 495996cfc49a1c6eefde6ff04fc75e0739be3aab)
