This patch adds documentation for the new kconfig-package infrastructure to

Note that due to the simplicity of the infrastructure, the documentation
is not split in a 'tutorial' and a 'reference', like for the other
infrastructures. Instead, the usage is described in one section.

As reported in bug #7172 [0], setting BR2_TARGET_LDFLAGS to a value
containing a $ sign can lead to unexpected results.
This is because it is very hard to know when the $ sign gets evaluated:
- in the Buildroot-level make
- in the shell called by the Buildroot-level make
- in the package's own build-system, either at configure time, in the
Makefile, in a shell in the Makefile...
So, it is very difficult to know how much escaping that would need.
A proposal is to use a shell variable to pass such values unmolested.
But it is not that simple either, since it still contains a $ sign, and
there is not much certainty as to when it would be evaluated.
Instead, just document this limitation, both in the help text for
BR2_TARGET_LDFLAGS, and in the known-issues section in the manual.
Does not really fix#7172, but at least the limitation is documented.

The inner-xxx-targets in the buildroot package infrastructures are
evaluated using $(eval) which causes variable references to be a bit
different than in regular make code. As we want most references to be
expanded only at the time of the $(eval) we should not use standard
references $(VAR) but rather use double dollar signs $$(VAR). This includes
function references like $(call), $(subst), etc. The only exception is the
reference to pkgdir/pkgname and numbered variables, which are parameters to
the inner block: $(1), $(2), etc.
This patch introduces consistent usage of double-dollar signs throughout the
different inner-xxx-targets blocks.
In some cases, this would potentially cause circular references, in
particular when the value of HOST_FOO_VAR would be obtained from the
corresponding FOO_VAR if HOST_FOO_VAR is not defined. In these cases, a test
is added to check for a host package (the only case where such constructions
are relevant; these are not circular).
Benefits of these changes are:
- behavior of variables is now again as expected. For example, setting
$(2)_VERSION = virtual in pkg-virtual.mk will effectively work, while
originally it would cause very odd results.
- The output of 'make printvars' is now much more useful. This target shows
the value of all variables, and the expression that led to that value.
However, if the expression was coming from an inner-xxx-targets block, and
was using single dollar signs, it would show in printvars as
VAR = value (value)
while if double dollar signs are used, it would effectively look like
VAR = value (actual expression)
as is intended.
This improvement is for example effective for FOO_DL_VERSION, FOO_RAWNAME,
FOO_SITE_METHOD and FOO_MAKE.
The correctness of this patch has been verified using 'make printvars',
'make manual' and 'make legal-info' before and after applying this patch,
and comparing the output.

There will soon be new options to the graph-depends script, which we
can only sanely pass via environment variables.
Currently, we use such an environment variable to pass the maximum depth
of the dependency graph; the name of that variable is explicit that it
contains just the depth.
However, there has been so far no release of Buildroot which would make
use of that variable, so no user should have come to rely on it.
Rename that variable so it is less specific, and more generic, so it can
be used to pass more options to graph-depends.

For asciidoc, a string like '+these are some words+' will be displayed in
monospace font. Such sequences are identified by searching for a matching
pair of + signs in the same block.
The string 'C++' also contains such + signs. In most cases, this does not
pose a problem and no escaping is necessary. However, if 'C++' occurs twice
in the same block, the + signs will be matched to each other, and asciidoc
formats all text between them as monospaced text. In this case, escaping of
one of these 'C++' occurances is necessary to get the right formatting.
In one place of the manual, there is a sentence that causes such a problem:
"you only have to tell whether your toolchain supports C++ or not and
whether it has built-in RPC support. If your external toolchain uses
the 'uClibc' library, then you have to tell Buildroot if it supports
largefile, IPv6, RPC, wide-char, locale, program invocation, threads
and C++."
Commit 082dec8ce4 was based on a patch fixing
this problem in one place of the manual, but was incorrectly changed while
committing.
This patch reverts the incorrect changes in that commit, and solves the
problem correctly.

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.
