abd4124e5f manual: add section about dealing efficiently with big image files
As reported by Ryan, it is not well-known that most tools can deal
efficiently with big sparse files.

Add a section in the manual about this, with tar and cp used as
examples, and a hinting to the man pages for the others.

4e2b7057c6 manual: use current date/time for 'generated on'
Currently, the manual uses the last modification date and time of
manual.txt in the generated manual.

This is confusing, especially for long-checked-out repositories where
the top-level manual.txt has not changed since the check out. Moreover,
the manual explicitly states 'generated on', which is confusing at best.

Use the current date and time instead.

f1fedbb246 graphs: support generating png graphs
PDF files can not be easily embedded in other documents (eg. ODT, or HTML).

f4ea4b9824 Config.in: Add a menu around BR2_EXTERNAL configuration options
To make it clear to the user that these options are external to Buildroot
and no support is provided by the Buildroot community.

With this, there's no need to recommend people to their options inside
a menu, so remove that from the documentation.

Kconfig nicely allows us to hide the menu completely if BR2_EXTERNAL isn't
used, so make use of that to not confuse people. It would be nice if we
could add some help text to explain the BR2_EXTERNAL stuff as well, but
that isn't supported on menus :/

a4239f7fd1 core: introduce the BR2_EXTERNAL variable
This commit introduces the BR2_EXTERNAL environment variable, which
will allow to keep Buildroot customization (board-specific
configuration files or root filesystem overlays, package Config.in and
makefiles, as well as defconfigs) outside of the Buildroot tree.

This commit only introduces the variable itself, and ensures that it
is available within Config.in options. This allows us to use
$BR2_EXTERNAL in a 'source' statement in Config.in.

Following patches extend the usage of BR2_EXTERNAL to other areas
(packages and defconfigs).

In details, this commit:

 * Introduces the BR2_EXTERNAL Kconfig option. This option has no
   prompt, and is therefore not visible to the user and also not
   stored in the .config file. It is automatically set to the value of
   the BR2_EXTERNAL environment variable. The only purpose of this
   BR2_EXTERNAL Kconfig option is to allow $BR2_EXTERNAL to be
   properly expanded when used inside Kconfig source statements.

 * Calculates the BR2_EXTERNAL value to use. If passed on the command
   line, then this value is taken in priority, and saved to a
   .br-external hidden file in the output directory. If not passed on
   the command line, then we read the .br-external file from the
   output directory. This allows the user to not pass the BR2_EXTERNAL
   value at each make invocation. If no BR2_EXTERNAL value is passed,
   we define it to support/dummy-external, so that the kconfig code
   finds an existing $(BR2_EXTERNAL)/package/Config.in file to
   include.

 * Passes the BR2_EXTERNAL into the *config environment, so that its
   value is found when parsing/evaluating Config.in files and .config
   values.

f678e31086 manual: do not generate .pyc files
Python saves a pre-compiled support/scripts/kconfiglib.pyc file
side-to-side with the corresponding .py file.

This does not work if the Buildroot source tree is read-only (but
this is not an error for Python, which keep going OK).

But this may cause issues for out-of-tree builds in case the same
Buildroot source tree is shared by many builds.

Also, 'make clean' currently does not clean this file, and out-of-tree
builds can remove it either, at the risk of causing issues for other
out-of-tree builds running at the same time.

Just tell Python not to generate .pyc files:
  - call the script via python, don't use the sha-bang
  - thus, make the script non-executable, and remove the sha-bang

09dea8e8fb docs/manual: limit the depth of the TOC in the HTML output
The current TOC level is set to 4, which does not mean 'a 4-level deep TOC',
but really means 'a TOC deep to the 4th level', with the first level being
level 0, which means we have:

    12. Appendix
        12.1. Makedev syntax documentation
        12.2. Makeuser syntax documentation
        12.3. Partition table layout description syntax
            12.3.1. The global section
                Properties for the global section

Which a bit too much. And yet, the fifth level is not shown, since we
don't have any! :-/

Limit the depth of the TOC to three levels, which is just enough to be
usefull, yet not cluttered by low-level titles.
