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.

getopt(3) returns int type not char. Using char triggers the
-Wtautological-constant-out-of-range-compare warning with clang.
Change the type of the variable used for holding the return value
of getopt(3) to int to match the prototype and eliminate the warning.

When building WITH_BEARSSL=1 veriexec(4) failes to compile.
So update the function prototype so that veriexec(4)
compiles again.

During software installation, use veriexec -S to strictly
enforce certificate validity checks (notBefore, notAfter).
Otherwise ignore certificate validity period.
It is generally unacceptible for the Internet to stop working
just because someone did not upgrade their infrastructure for a decade.
