MFC r308945:
Set the 'vital' flag on the runtime and jail packages.

The default pkg(8) from pkg.freebsd.org requires libjail.so,
so mark the jail package as vital along with the runtime
package to avoid errors when libjail.so is removed. This is
a no-op for systems with WITHOUT_JAIL in src.conf(5) and pkg(8)
built from the Ports Collection.

In order to make this work without marking packages such as
the jail-lib32, for example, the jail.ucl file needed to be
split out into separate files similarly to the runtime-*.ucl
files.

Fix permissions on /tmp when installing the runtime package.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Add (commented) 'vital' flag to the runtime packages. Support for
it is expected in pkg-1.8.0, which will cause 'pkg del -afy' to not
destroy a system by forcefully removing everything.

As there are valid use cases for doing such (test jails, for example),
it will be overrideable.

In addition, ensure /dev and /tmp exist, as /dev is not created by
default currently, and pkg(8) requires /tmp to exist, which is also
not created by default.

This needs to be moved to the clibs package, since runtime depends on
that package, however I need to first verify that it will work as it
is expected.

Merge the projects/release-pkg branch to head.

This allows packaging the base system with pkg(8), including
but not limited to providing the ability to provide upstream
binary update possibilities for non-tier-1 architectures.

This merge is a requirement of the 11.0-RELEASE, and as such,
thank you to everyone that has tested the project branch.

Documentation in build(7) etc. is still somewhat sparse, but
updates to those parts will follow.

Remove libc, librtld_db, libthr packages, and further increase
the constraints on what needs to be installed in a specific to
maintain consistency during upgrades.

Create a new clibs package containing libraries that are needed
as a bare minimum for consistency.

Add package files for libc, libedit, librtld_db, and libthr.

libedit is needed for sh(1), which if updated before runtime,
can cause undesirable behavior.

For the rest, the installation order needs to be:

1) librtld
2) libc
3) libthr

The dependency listing and shilbs_required entries ensure this
behavior.

Rework the way <packagename>.ucl files are generated.
One of the major pain points with how this was implemented
is the requirement of in-tree, hard-coded <name>.ucl, as
well as <name>-<suffix>.ucl where <suffix> can be lib32,
profile, development, debug, or any combination of the four.

This created significant overhead when adding new packages
and any of the files in any of the combinations were missing.

Instead of test(1)-ing if the <packagename>.ucl file exists,
hand off to a script to figure out what the final ucl file
name should be before invoking pkg(8).

The default behavior is 'template.ucl' is used as a fallback.

This affects only the userland packages, as the kernel code
is already smart enough to handle these variations.

Fix script syntax

Make scripts cross installation friendly

run pw_mkdb and cap_mkdb at post-installation for cross installation the version
from the host would be run but the generated files will be on the target
respecing the endianness of the target

Now that pkg create can directly accept both a file and a plist in command line,
directly use it

Add new create-world-packages target to generated the packages out of world

Dynamically figure out the list of targets based on tags passed on the mtrees
First sanity check that all packages have existing manifests
Generate the packages

Please note that for now the mtree needs more work as it has duplicate entries,
everything is not yet tagged

The packages now have generic entries and needs to be customize
