audit: allow interfield comparison in audit rules
We wish to be able to audit when a uid=500 task accesses a file which is
uid=0. Or vice versa. This patch introduces a new audit filter type
AUDIT_FIELD_COMPARE which takes as an 'enum' which indicates which fields
should be compared. At this point we only define the task->uid vs
inode->uid, but other comparisons can be added.
