pkgbase: Create a FreeBSD-utilities package and make it the default one

The default package use to be FreeBSD-runtime but it should only contain
binaries and libs enough to boot to single user and repair the system, it
is also very handy to have a package that can be tranform to a small mfsroot.
So create a new package named FreeBSD-utilities and make it the default one.
Also move a few binaries and lib into this package when it make sense.

Fix STAGE_DIR.* to handle indirect *DIR variables.

bsd.{files,conf}.mk recently changed to allow *DIR to name a variable

Whitespace only change, no functional change intended.

The padding makes it much easier to read, but occasionally means that commits
like this one have to be done to follow up. I intentionally kept this
separate from r336841 to try and make things easier to follow later on.

DIRDEPS_BUILD: Fix '/' in group names creating a bad cookie.

This is reworking the change in r296585 but to still properly install
the files. This limits the change to only the DIRDEPS_BUILD logic
for what it considers the name of the staging set, which is what the
cookie name is based off of.

Revert r296585.

This broke installing dtrace test files. It was poorly tested.

These group names may be used as a cookie, so replace any non-fs-safe characters.

One example is in cddl/usr.sbin/dtrace/tests/common/aggs. It could be
fixed but other uses of this would break, especially in the
DIRDEPS_BUILD which uses the group names for stage cookies.

DIRDEPS_BUILD: Fix some things building in MAKELEVEL0.

For PROGS this was recursing twice since MAKELEVEL0 is for 'dirdeps'

META MODE: Fix after addition of bsd.confs.mk: Stage in "files" set.

The "files" staging name is not the same as "bsd.files.mk" but seems to just be
a group of extra files that are not the essential includes or libraries, which
include .

Configs should not be under MK_INCLUDES control.

'buildconfig' is connected to 'all', but 'installconfig' is only called
manually. There is not much need to conditionalize this file right
now due to how it is hooked up and its impact on various build phases.

Make installing to a non-existent directory an error.

Before this, if a file was installed to DESTDIR/some/dir and that directory
was missing due to not having ran 'make distrib-dirs' yet, the file would
be installed as 'some/dir'. For something like bsd.incs.mk with INCLUDEDIR
being a sub-directory of /usr/include, this could result in all of the headers
being installed to a file rather than getting a directory of them.

Now it will error that the file/directory does not exist rather than hide
the issue.

Another option being discussed is to implement GNU's install -D flag which
would auto create any missing directories.

This is a mitigation of the problem. The proper order to the build is to
run 'make distrib-dirs' first, but that can be forgotten if building from
a sub-directory after updating the source code to the latest revision.

Revert r289282 for now as the interaction with a directory containing
bsd.files.mk and bsd.subdir.mk is recursing too many times.

Replace the out-of-place includes/files/config handling in bsd.subdir.mk with
more typical ALL_SUBDIR_TARGETS entries and target hooks in bsd.incs.mk,
bsd.files.mk and bsd.confs.mk.

This allows the targets to be NOPs if unneeded and still work with the
shortcut 'make includes' to build and then install in a parallel-safe manner.

Sort and re-indent the ALL_SUBDIR_TARGETS with the new entries.
