Peter has just pointed me to the PGP signatures of the release tarballs,
which exist since he's been doing releases.
This was not obvious to me that the releases were signed, as there was
no info about it on the website.
So, add such links on the downloads page.

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.

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.

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 :/

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.

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

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.

Allow user to supply their own step-hooks by passing a variable
on the make command-line:
make BR2_INSTRUMENTATION_SCRIPTS=/path/to/my/script
This can be useful to run site-specific actions at each step of the
build process, such as logging installed, removed or modified files,
do sanity checks on installed files...
It is possible to call more than one script, by passing a space-separated
lists of scripts to call.

Split out the information on hooks to a separate section (and source file).
Not only because the hooks are useful for all infrastructures (and thus
don't really fit specifically in the generic infrastructure section), but
also for clarity when the info on hooks will be expanded in later patches.

One of the use cases is for the 'local packages' to restore
the SCM info. Some packages use this information to generate
version info during build time. In this case, the local package
can have this hook to restore it by symbolic link for example.
