Add support for packages to enable SELinux modules already supported by
the refpolicy, but not selected by default in its policy.
With this commit, packages will be able to do something like:
SYSTEMD_SELINUX_MODULES = systemd udev
to enable additional SELinux modules.

The refpolicy is configured to use a monolithic build, compiling all the
available modules (whether they're 'base' or 'modules' ones) in the
binary policy. The result is a quite big SELinux policy, with a lot more
rules than what would be needed in a Buildroot image.
Refactor the refpolicy build configuration to enable less modules by
default. To achieve this, all the modules marked as being part of the
'base' policy are kept but all the modules marked as being only
'modules' are disabled. Then a static list of modules (in addition to
the already selected 'base' ones) are enabled. The result is a much
smaller refpolicy: tests showed a reduction of the binary policy from
2.4M to 249K (~90% smaller).
This minimal set of SELinux modules should allow to boot a system in
enforcing mode in the future. It currently does not work, not because
extra modules are needed, but because of required changes within the
selected modules.
This patch would break backward compatibility as the refpolicy will no
longer have all the modules provided by the project, but only those
selected. This should not be an issue as this configuration was not
suitable directly for a real system. Modifications had to be done. If we
still find out later that this is an issue for someone, we'll have the
ability to mimic what was done previously thanks to other mechanisms
(such as providing the upstream policy as a "custom" policy location).

Set the SELinux file security contexts using setfiles when generating
root filesystem images.
Without such security contexts created at build time, they need to be
setup at first boot by running the restorecon utility on the target.
This has two drawbacks:
- You have to special case the first boot, which cannot be done in
enforcing mode, and will have to run restorecon, then reboot.
- You cannot support read-only filesystems.
By setting up the security contexts at build time, we can have a
filesystem image that is immediately ready to boot an SELinux system
in enforcing mode, including if the root filesystem is read-only.

Mg is a small Emacs-like editor with no external dependencies except a
standard C library. It weighs in at 130 kiB and is one of a select few
completely free (public domain) text editors suitable for small and
embedded systems.
This version is based on the OpenBSD Mg, but with more features, one of
which being the no-ncurses/termcap support, which heavily reduces the
impact on a resource constrained system.

By default, the iputils build script might build binaries which are
useless for certain applications, like tftpd or ninfod. Those binaries
will add to the target filesystem size unless a post-build script removes
them manually, which is cumbersome and doesn't shorten build times.
In particular, in a certain aarch64 Buildroot project with musl selected
as a C library, this patch allowed to shrink the full iputils package from
219 KiB (if every option is selected) to 63 KiB (with only the ping
binary selected) - a 71.2% relative size decrease.
Moreover, upstream recently introduced a commit that disabled tftpd from
building by default, like rarpd. In the current state of things, this change
will introduce inconveniences for Buildroot users which prefer to use the
tftpd implementation provided by this package. With this patch, however, that
decision and similar future ones won't be a concern, because they will
have complete control of what binaries are built.
These changes add Kconfig options which let the user select what
binaries are built with ease.

Switch to "$(INSTALL) -d" which allows us to be explicit about the

The AmLogic Odroid C2 boards use an ATF version for which the source
code is not available. The mainline U-Boot documentation at
doc/board/amlogic/odroid-c2.rst details how to build a bootable U-Boot
image for this platform: it requires fetching the ATF binary files
from https://github.com/hardkernel/u-boot.git as well as a tool called
fip_create from the same repository.
This commit therefore implements a simple Buildroot package that
retrieves this repository, installs the firmware files, and
builds/installs the host fip_create utility.
This package really installs target images (firmware files) and one
host utility, so we had to take an arbitrary decision on whether it
should be a target package or a host package, and we've chosen to make
it a target package.
