diff3(1): Rewrite Makefile by using SCRIPTS

Meanwhile, rename the script "diff3" to "diff3" to work with SCRIPTS.

diff(1): Remove unnecessary "-Wall" COPTS

The "-Wall" option is already set by default.

That was auto-generated in FreeBSD's code base; we don't need it.

sockstat(1): Fix and improve output formatting

The main issue with the old formatting was that the FD column was
limited to 2 characters, so there would be no space between FD and PROTO
columns.

Increase the FD column to 5 characters, and increase the PID column to
6 characters. In addition, refactor the output formatting code to clean
up the mess.

While there, clean up the code a bit to save some type castings.

dsynth - Adjust /boot mounts for chroot

* Fix issue where Intel microcode couldn't be installed within the
chroot due to trying to write into /boot.

* Replace /boot null-mount with a /boot tmpfs and mkdir /boot/modules.local.
Leave other /boot directories unpopulated for now (we'll fix that if we
hit problems). i.e. no /boot/kernel or anything else is in the chroot
any more.

* This also allows us to remove the /boot/modules.local tmpfs mount we had
before, improving performance slightly.

Add integrated dports build feature to build-all and install-all targets

Add integrated dports build feature to build-all and install-all targets

When WITH_DPORTS=YES is used build-all and install-all, these targets will
also build the base set of ports and all of their dependencies using
configuration data and the "dragonfly/base" dport found in
"/usr/src/dports.base".

This feature is intended to be used by the nrelease build in an upcoming
commit, and may also be used manually.

The /usr/dports tree must exist and contains the dports repo to use as the
basis of the dports build. It will be null-mounted in the chroot and the
"/usr/src/dports.base/dragonfly" directory will be null-mounted under it
to provide the "dragonfly/base" meta-port. The DPORTSBASE make variable
may be used to override the location of the main dports repo.

The build-all and install-all targets use a sophisticated chrooted
environment to do a completely clean dports build with dsynth. It
It will actually "make installworld" plus a clean "make distribution"
inside the chroot environment to create the environment, and the host
system's /etc/resolv.conf will be copied in.

build-all - Augmented when used WITH_DPORTS=YES
install-all - Augmented when used WITH_DPORTS=YES
buildportschroot - Build a fresh chroot environment for dsynth
mountports - Do all null mounts and cp's needed for the env
buildports - Run dsynth build dragonfly/base in the env
installports - Install the built ports on the host system (see note)
umountports - Remove the null mounts

WITH_DPORTS=YES - executes buildportschroot, mountports, buildports,
and umountports when run from build-all.

executes mountports, installports, umountports
when run from install-all.

DPORTSBASE=path - Defaults to /usr/dports, may be used to override
the location where the main dports tree can be
found.

NOTE: Installports may require interactivity as the base system might already
have installed ports. Generally speaking it is best to not revert any
ports you might already have installed, so feel free to tell it not to
install anything.

* Added various make targets and augmented build-all and install-all

* /usr/local/sbin added and the stale /usr/pkg/bin removed from _HOSTPATH.

* Add /usr/src/dports.base infrastructure.

It contains the dsynth.ini and pkg.conf files that will be used for the
local dsynth operations. Some paths are replaced with SED when copied
to the chroot. The dsynth.ini is relative to the chroot.

It also contains the dragonfly/base dport which is the meta-port that
dsynth will be told to build.

All other dports related files and directories are null-mounted from
/usr/dports.

* Add /usr/distfiles.base to mtree/BSD.usr.dist. This directory is also
created by the build if it does not exist since the host system might
not have run a new installworld recently.

This directory will be used during build-all (buildports) to store the
distfiles required to build dragonfly/base, so they only need to be
fetched once.

* Add the "-C ConfigBase" option to dsynth to make running it from the
chrooted environment easier. This overrides the /etc/dsynth directory
and removes /etc/dsynth as a fallback.

* dsynth conditionalizes calling syscap_set() for backwards compatibility
with older host systems that might not have been upgraded to include the
feature yet.
