[Buildroot] [PATCH] manual: use one-line titles instead of two-line titles (trivial)

[Peter Korsgaard <jacmet@uclibc.org>]

 > 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.
