Each boot, regenerate /var/run/os-release based on the currently running
system. Create a /etc/os-release symlink pointing to this file (so that this
doesn't create a new reason /etc can not be mounted read-only).
This is compatible with what other systems do and is what the sysutil/os-release
port attempted to do, but in an incomplete way. Linux, Solaris and DragonFly all
implement this natively as well. The complete standard can be found at
https://www.freedesktop.org/software/systemd/man/os-release.html
Moving this to the base solves both the non-standard location problem with the
port, as well as the lack of update of this file on system update.

Summary:
Historically, we have built toolchain components such as cc, ld, etc as
statically linked executables. One of the reasons being that you could
sometimes save yourself from botched upgrades, by e.g. recompiling a
"known good" libc and reinstalling it.
In this day and age, we have boot environments, virtual machine
snapshots, cloud backups, and other much more reliable methods to
restore systems to working order. So I think the time is ripe to flip
this default, and link the toolchain components dynamically, just like
almost all other executables on FreeBSD.
Maybe at some point they can even become PIE executables by default! :)

This change allows to specify a watchdog(9) timeout for a system
shutdown. The timeout is activated when the watchdogd daemon is
stopped. The idea is to a prevent any indefinite hang during late
stages of the shutdown. The feature is implemented in rc.d/watchdogd,
it builds upon watchdogd -x option.
Note that the shutdown timeout is not actiavted when the watchdogd
service is individually stopped by an operator. It is also not
activated for the 'shutdown' to the single-user mode. In those cases it
is assumed that the operator knows what they are doing and they have
means to recover the system should it hang.
Significant subchanges and implementation details:
- the argument to rc.shutdown, completely unused before, is assigned to
rc_shutdown variable that can be inspected by rc scripts
- init(8) passes "single" or "reboot" as the argument, this is not
changed
- the argument is not mandatory and if it is not set then rc_shutdown is
set to "unspecified"
- however, the default jail management scripts and jail configuration
examples have been updated to pass "jail" to rc.shutdown, just in case
- the new timeout can be set via watchdogd_shutdown_timeout rc option
- for consistency, the regular timeout can now be set via
watchdogd_timeout rc option
- watchdogd_shutdown_timeout and watchdogd_timeout override timeout
specifications in watchdogd_flags
- existing configurations, where the new rc options are not set, should
keep working as before
I am not particularly wed to any of the implementation specifics.
I am open to changing or removing any of them as long as the provided
functionality is the same (or very close) to the proposed one.
For example, I think it can be implemented without using watchdogd -x,
by means of watchdog(1) alone. In that case there would be a small
window between stopping watchdogd and running watchdog, but I think that
that is acceptable.

Summary: When powerpc64 switches to LLVM, use this patch to enable
OpenMP as well. OpenMP on PPC is only for 64-bits, so don't make a
32-bit libomp. A change to openmp files is necesssary (under review on
https://reviews.llvm.org/D67190), because it determines ELF format
version based on endianness, which is incorrect.

boot block area. That can be less than 2 if PAGE_SIZE is big.
swapon(8) has an option to trim (delete) all the blocks of a device at
startup. However, if the first of those blocks is a bsd label, then
trimming those blocks is destructive. Change swapon to leave the
first BBSIZE bytes untrimmed.
Update manual pages to reflect changes in how swapon and how it may be
used, espeically in association with savecore.

rcmds were removed in r32435 and these three man pages can trivially
drop the references.
There's still a reference in pts.4 because it describes a mode
(TIOCPKT_NOSTOP), and only lists rlogin/rlogind as examples of programs
that use that mode. To update later.

Previously fusefs would never recycle vnodes. After VOP_INACTIVE, they'd
linger around until unmount or the vnlru reclaimed them. This commit
essentially actives and inlines the old reclaim_revoked sysctl, and fixes
some issues dealing with the attribute cache and multiply linked files.
