Add two functions for parsing the iovctl config file. The config
file is parsed using libucl[1], which accepts most YAML files and
a superset of JSON. The first function is an ad-hoc parser that
searches the file for the PF.DEVICE configuration value. We need
to know that value in order to fetch the schema from the kernel,
and we need the schema in order to be able to fully parse the file.
The second function parses the config file and validates it
against a schema. This function will exit with an error message
if any validation error occurs. If it succeeds, the configuration
is returned as an nvlist suitable for passing to the kernel.

Add an function to iovctl that validates the configuration against
a schema. This function is able to assume that the parser has
done most of the validation already and it's only responsible for
applying default VF values specified in the config file, confirming
that all required parameters have been set and that no invalid VF
numbers have been specified.

jail's creation parameters. This allows the kernel version to be reliably
spoofed within the jail whether examined directly with sysctl or
indirectly with the uname -r and -K options.
The values can only be set at jail creation time, to eliminate the need
for any locking when accessing the values via sysctl.
The overridden values are inherited by nested jails (unless the config for
the nested jails also overrides the values).
There is no sanity or range checking, other than disallowing an empty
release string or a zero release date, by design. The system
administrator is trusted to set sane values. Setting values that are
newer than the actual running kernel will likely cause compatibility
problems.

The default remains localtime for compatibility with the original device model
in bhyve(8). This is required for OpenBSD guests which assume that the RTC
keeps UTC time.

That it went this long without anyone noticing is a sign that this feature
isn't actually used by anyone, but it's there so it might as well work.

leak kernel internal stuff, reconnect ifmcstat(1) back to build. However,
disable kvm(3) support in it, since it requires uncovering tons of _KERNEL
defined declarations, which can be achieved either uncovering them globally
or providing dirty hacks such as _WANT_IFADDR. If anyone demands an
ifmcstat-like kvm-based tool, please take the code out of usr.sbin/ifmstat
and create a tool in src/tools/tools.
On POSIX conformant systems, shutdown() should return ENOTCONN when not
connected. We attempted to fix this once (kern/84761), but this change
got backed out because it 'breaks code' (r150155).
I just reapplied the patch and indeed, syslogd fails on startup. Make it
easier to re-enable this change in the future by paching up syslogd to
do the right thing.

ifmcstat(8) noses in kernel memory too much, and thus is very tentative
to any changes in kernel.
I will rewrite it to use some API instead of libkvm(3) and connect back
to build.
Add missing references to $BASEDIR, in order to allow correct operation
when updating a system mounted at another location than / (e.g. when
updating an alternate Boot Environment).

update paths; and include everything in the "base" distribution.
The "games" distribution being optional made sense when there were more
games and we had small disks; but the "games-like" games were moved into
the ports tree a dozen years ago and the remaining "utility-like" games
occupy less than 0.001% of my laptop's small hard drive. Meanwhile every
new user is confronted by the question "do you want games installed" when
they they try to install FreeBSD.
The next steps will be:
2. Removing punch card (bcd, ppt), phase-of-moon (pom), clock (grdc), and
caesar cipher (caesar, rot13) utilities. I intend to keep fortune, factor,
morse, number, primes, and random, since there is evidence that those are
still being used.
3. Merging src/games into src/usr.bin.
This change will not be MFCed.

unmount, which causes error from nmount(2) call when performing
MNT_DELEXPORT over the directory which ceased to be a mount point.
The race is legitimate and innocent, but results in the chatty mountd.
Silence it by providing an distinguished error code for the situation,
and ignoring the error in mountd loop.
