Currently, the linux kernel will apply some fixups on its .config file,
based on whether some packages are enabled or not. That list of
conditional fixups is getting bigger and bigger with each new package
that needs such fixups, culminating with the pending firewalld one [0].
Furthermore, these fixups are not accessible to packages in br2-external
trees.
Add a new per-package variable, that packages may set to the commands to
run to fixup the kernel .config file, which is added at the end of the
linux' own fixups.
This opens the possibility to write things like;
define FOO_LINUX_CONFIG_FIXUPS
$(call KCONFIG_ENABLE_OPT,BLA)
endef
Of course, it also opens the way to run arbitrary commands in there, but
any alternative that would be declarative only, such as a list of
options to enable or disable (as an example):
FOO_LINUX_CONFIG_FIXUPS = +BAR -FOO +BUZ="value"
.. is not very nice either, and such lists fall flat when a value would
have a space.
For packages that we have in-tree, we can ensure they won't play foul
with their _LINUX_CONFIG_FIXUPS. For packages in br2-external trees,
there's nothing we can do; users already have the opportunity to hack
into the linux configure process by providing LINUX_PRE_CONFIGURE_HOOKS
or LINUX_POST_CONFIGURE_HOOKS anyway...
.. which brings the question of why we don't use that to implement the
per-package fixups. We don't, because _PRE or _POST_CONFIGURE_HOOKS are
run after we run 'make oldconfig' to sanitise the mangled .config.

since v234 upstream recommands using systemctl preset-all to enable units.
* add a buildroot specific preset file
* use that file to disable getty@tty1
* make systemd depend on host-systemd
* remove all link-creating code that systemd does for us.
Most packages will not be affected by this change, but a few packages
were installing units without manually enabling them. Those packages
will now be automatically enabled.
The fact that those packages were not enabled is almost certainly a bug,
but it is a change of behaviour that needs to be reported
host-systemd also builds udevadm for the host. That means we no longer
need to depend on host-eudev to provide udevadm (that would conflict).

Currently, the formatting we impose on the _LICENSE variable requires
that we also use the rarely used := assignment operator, which makes
the _LICENSE variable the only variable that users have to write with
this operator.
This really departs from the simplicity and consistency of using the
append-assignment, which we use for every other variable.
This is because the append-assignment operator surreptiously
introduces a space between the original value and the appended one. But
we can use this knowledge, to match any instance of a space followed by
a comma, and turn it into a single comma.
This allows users to now have a consistent use of the '=' and '+='
operators we use everywhere else in .mk files.

For various reasons, we've always suggested users to avoid using a
branch as version string for their packages, because it does not work
as a they would expect:
- it is not reproducible, because the branch may change between two
builds that are done at different times;
- it does not even follow the branch, as Buildroot anyway generates
a local tarball, which it will reuse on subsequent builds.
Furthermore, since we fetch and not pull, any existing local branch
is not updated.
Yet, until recently, using a branch name would just work (with the
above limitations): the git tree was cloned, the branch checked out,
and the tarball created.
But with the advent of the git caching, using a branch name does not
work anymore. Indeed, we now do a git-fetch, and that does not create
a local master branch. So we can't check out master, because it does
not exist locally. And for other branches, as noticed above, the local
branch does not get udpated to the remote one.
Furthermore, the local branches are only created by chance, again as a
side-effect of trying to fetch the "special refs".
So, we can't say that we reliably support the use of a branch name.
Update the manual to state that using a branch does not work. Remove
the 'stable' example, as it looked like the name of a stable branch;
instead, replace it with a version string that ressemble a tag.
Fix the layout of the manual by making the version examples an actual
bulleted list.
Note: the above is only entirely true for git. For Mercurial, CVS and
subversion, the status may be mixed, but nonetheless, using branches is
still a bad idea, if at least because it is not reproducible, and
because Buildroot does not even follow the branch. So, we do not
differentiate between the various SCMs, and just flatly state that using
a branch name is not supported.

Extract dependencies are dependencies that must be ready before the
extract step of a package, i.e for tools that are needed to extract
packages themselves. Current examples of such tools are host-tar,
host-lzip and host-xz.
They are currently handled through DEPENDENCIES_HOST_PREREQ. However,
this mechanism has a number of drawbacks:
- First and foremost, because host-tar/host-lzip/host-xz are not
listed in the dependencies of packages, the package infrastructure
does not know it should rsync them in the context of per-package
SDK.
- Second, there is no dependency handling *between* them. I.e, we
have no mechanism that says host-tar should be built before
host-lzip, while it is in fact the case: if you need to build
host-lzip, you need to extract a tarball, so you may need host-tar
if your system tarball is not capable enough.
For those reasons, it makes sense to add explicit support for "extract
dependencies" in the package infrastructure, through the
<pkg>_EXTRACT_DEPENDENCIES variable. It is unlikely this variable will
ever be used by a package .mk file, but it will be used internally by
the package infrastructure.

Asciidoc supports two syntaxes for section titles: two-line titles (title
plus underline consisting of a particular symbol), and one-line titles
(title prefixed with a specific number of = signs).
The two-line title underlines are:
Level 0 (top level): ======================
Level 1: ----------------------
Level 2: ~~~~~~~~~~~~~~~~~~~~~~
Level 3: ^^^^^^^^^^^^^^^^^^^^^^
Level 4 (bottom level): ++++++++++++++++++++++
and the one-line title prefixes:
= Document Title (level 0) =
== Section title (level 1) ==
=== Section title (level 2) ===
==== Section title (level 3) ====
===== Section title (level 4) =====
The buildroot manual is currenly using the two-line titles, but this has
multiple disadvantages:
- asciidoc also uses some of the underline symbols for other purposes (like
preformatted code, example blocks, ...), which makes it difficult to do
mass replacements, such as a planned follow-up patch that needs to move
all sections one level down.
- it is difficult to remember which level a given underline symbol (=-~^+)
corresponds to, while counting = signs is easy.
This patch changes all two-level titles to one-level titles in the manual.
The bulk of the change was done with the following Python script, except for
the level 1 titles (-----) as these underlines are also used for literal
code blocks.
This patch only changes the titles, no other changes. In
adding-packages-directory.txt, I did add missing newlines between some
titles and their content.
