setfacl: add recursive functionality

Add a -R option to setfacl to operate recursively on directories, along
with the accompanying flags -H, -L, and -P (whose behaviour mimics
chmod).

A patch was submitted with PR 155163, but this is a new implementation
based on comments raised in the Phabricator review for that patch
(review D9096).

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Switch to our preferred license text.

style(9) cleanups mostly consisting of:
o explicitly check return values and variables against a value
o return x; -> return (x);
o fix inconsistent sysexits usage by nuking it (partially
suggested by bde)

o Correct error message forgotten in the last commit (malloc() -> calloc())
o Fix style nits

Use calloc(3) instead of rolling our own.

o POSIX.2c Userland tool support for POSIX.1e ACLs -- getfacl retrieves ACLs
from files and directories, and setfacl sets ACLs on files and directories.
