The structure of the buildroot manual is not always clear. There is a large
number of chapters, and some chapters seem to overlap. The distinction
between general usage and developer information is not always clear.
This patch restructures the manual into four large parts:
- getting started
- user guide
- developer guide
- appendix
Except for the names of these parts, the section names are not yet changed.
Content-wise there are no changes yet either. This will be handled in
subsequent patches.
In order to achieve the introduction of a new level 'parts' above
'chapters', the section indicators (=, ==, ===, ...) of several sections
have to be moved one level down. Additionally, the leveloffset indication to
asciidoc has to be removed. Finally, to maintain more or less the same level
of detail in the table of contents, the toc.section.depth attribute is
reduced as well. Note that for some sections, less detail is visible now.

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.

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.

Add a 'Known issues' chapter, which lists the exceptions I have
currently in the autobuilder scripts to avoid known problems from
occuring. I believe it is more useful to document them rather than
keeping them hidden in my autobuilder script.
