[PATCH] Support for auditing on the actions of a not-yet-executed process.

eg: -a exit,always -F arch=b64 -S socket -F 'a0!=1' -F exe=/bin/bash -F success=1 to see instances of /bin/bash opening a non-local socket. Or -a exit,always -F arch=b64 -S socket -F 'a0!=1' -F exe_children=/bin/bash -F success=1 to instances of /bin/bash, and any descendant processes, opening a non local socket. proposed https://www.redhat.com/archives/linux-audit/2012-June/msg00002.html and it seemed like there was interest.
