This code was originally written for NetBSD. r306031 tried to adapt it to
FreeBSD, but didn't correctly handle the case that tmpfs was available, but
not already loaded. Fix the logic to load the module if necessary. The
tmpfs tests shouldn't be skipped anymore.
Also, fix a comment that was dislocated by r306031.

Code analysis and runtime analysis using truss(8) indicate that the only
privileged operations performed by ntpd are adjusting system time, and
(re-)binding to privileged UDP port 123. These changes add a new mac(4)
policy module, mac_ntpd(4), which grants just those privileges to any
process running with uid 123.
This also adds a new user and group, ntpd:ntpd, (uid:gid 123:123), and makes
them the owner of the /var/db/ntp directory, so that it can be used as a
location where the non-privileged daemon can write files such as the
driftfile, and any optional logfile or stats files.
Because there are so many ways to configure ntpd, the question of how to
configure it to run without root privs can be a bit complex, so that will be
addressed in a separate commit. These changes are just what's required to
grant the limited subset of privs to ntpd, and the small change to ntpd to
prevent it from exiting with an error if running as non-root.

Request init/fini array on FreeBSD 12 and later
Summary:
It seems a bad idea to change the default in the middle of a release
branch due to possible changes in global ctor / dtor ordering between
.ctors and .init_array. With FreeBSD 11.0's release imminent lets
change the default now for FreeBSD 12 (the current development
stream) and later.
FreeBSD rtld has supported .init_array / .fini_array for many years.
As of Jan 1 2017 all supported FreeBSD releases and branches will
have support.

auditd_wait_for_events() relies on read(2) being interrupted by signals,
but it registers signal handlers with signal(3), which sets SA_RESTART.
That breaks asynchronous signal handling. It means that signals don't
actually get handled until after an audit(8) trigger is received.
Symptoms include:
* Sending SIGTERM to auditd doesn't kill it right away; you must send
SIGTERM and then send a trigger with auditon(2).
* Same with SIGHUP
* Zombie child processes don't get reaped until auditd receives a trigger
sent by auditon. This includes children created by expiring audit trails
at auditd startup.
Fix by using sigaction(2) instead of signal(3).

For developers gensnmptree can now generate functions for enums to convert
between enums and strings and to check the validity of a value.
The sources in FreeBSD are now in sync with the upstream which allows to
bring in IPv6 modifications.
- Change the C++ directory entries to honor --sysroot if it is set.
- Don't define CROSS_INCLUDE_DIR for the cross compiler. Instead, set
TARGET_SYSTEM_ROOT to point to WORLDTMP and always define
STANDARD_INCLUDE_DIR.
- Change STANDARD_INCLUDE_DIR and the C++ include directories to just
start with "/usr" always. The compiler will prepend the sysroot when
doing cross-builds. GCC_INCLUDE_DIR (which contains headers that ship
with the compiler such as intrinsincs rather than OS-supplied headers)
remains hardcoded to look in TOOLS_PREFIX.

The local hostname was blindly copied into the to the nn_name array.
When the hostname exceeded 16 bytes, it would overflow. Truncate the
hostname to 15 bytes plus a 0 terminator which is the "workstation name"
suffix.
Use defensive strlcpy() when filling nn_name in all cases.

Upstream change ed47534 consciously added some redundant functional
