Simon J. Gerraty 1554ba03b6 Add mac_grantbylabel
This module allows controlled privilege escallation via mac labels
securely associated with a process via mac_veriexec.

There are over 700 PRIV_* but we can compress many of them into
a single GBL_* thus constraining the size of gbl labels.

The goal is to allow a daemon to run as an unprivileged process while
still being able a set of privileged operations needed.

We add APIs to libveriexec so that userland processes can check labels
and an exec_script API that allows a suitably labeled process to run
something like a python interpreter directly if necessary;
overcomming the 'indirect' flag applied to the interpreter.

Add -l option to sbin/veriexec to report labels.
