manual: fix manual generation in preparation for BR2_EXTERNAL support

This patch fixes an issue that occurs during the manual build process
which will occur when BR2_EXTERNAL is introduced.

During the package list generation, the python script using kconfiglib
module reads and parses the Config.in files. So, symbols, including
environment variables, got expanded and/or resolved.  In
kconfiglib.py, this patch fixes the regex that did not allow to use
numbers in the environment variable names, so '$BR2_EXTERNAL' got
wrongly expanded like it was '${BR}2_EXTERNAL':

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.

core: allow external Config.in/makefile code to be integrated

This commit allows the BR2_EXTERNAL directory to contain Config.in and
Makefile code, which gets integrated into the Buildroot build logic:

 - Buildroot automatically includes the $BR2_EXTERNAL/Config.in in the
   top-level configuration menu.

 - Buildroot automatically includes the BR2_EXTERNAL/external.mk in
   the build logic, so it can for example be used to include other .mk
   files that define package recipes.

This is typically intended to be used to create target packages in the
BR2_EXTERNAL directory, but can also be used for bootloaders, host
packages, or other custom make logic.

We also add a dummy Config.in file in support/dummy-external/ to
ensure that the source "$BR2_EXTERNAL/Config.in" line will point to an
existing file even when BR2_EXTERNAL is not used by the user.

core: allow external defconfigs to be used

This commit allows the user to store defconfigs in
$BR2_EXTERNAL/configs/. To achieve this:

 * It adds a new %_defconfig that looks in $BR2_EXTERNAL/configs/ for
   the corresponding defconfig file.

 * Updates the help target to also list external defconfigs.

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 :/
