cvs commit: src/sys/kern kern_mac.c src/sys/sys mac.h mac_policy.h

[Robert Watson]

FYI, this commit was slightly mis-ordered: I meant to commit it shortly
before a couple of the recent module commits, and realized afterwards that
I'd skipped it.  As a result, there may have been a short window where MAC
modules depended on changes in mac_policy.h and mac.h that weren't yet
present.  Hope this didn't cause too much inconvenience!
