Co-mingling two things here:
* Addressing some feedback from Konstantin and Kyle re: jail,
capability mode, and a few other things
* Adding audit support as promised.
The audit support change includes a partial refresh of OpenBSM from
upstream, where the change to add shm_rename has already been
accepted. Matthew doesn't plan to work on refreshing anything else to
support audit for those new event types.
