[PATCH v5 0/6] Improved seccomp logging

This is an update to the previous seccomp logging patch sets. The main difference in this revision compared to the last is that the application now has the ability to request that all actions in a filter, except for RET_ALLOW, should be logged. This is done with a new filter flag. In support of that change, the log_max_action sysctl was renamed to actions_logged as it now lists the actions that an admin has allowed to be logged. The admin has the final say in what actions get logged. Please see the individual patches for summaries of changes since the last revision. Thanks! Tyler
