Currently, we only support at most one br2-external tree. Being able
to use more than one br2-external tree can be very useful.
A use-case would be for having a br2-external to contain the basic
packages, basic board defconfigs and board files, provided by one team
responsible for the "board-bringup", while other teams consume that
br2-external as a base, and complements it each with their own set of
packages, defconfigs and extra board files.
Another use-case would be for third-parties to provide their own
Buildroot packaging in a br2-external tree, along-side the archives for
their stuff.
Finally, another use-case is to be able to add FLOSS packages in a
br2-external tree, and proprietary packages in another. This allows
to not touch the Buildroot tree at all, and still be able to get in
compliance by providing only that br2-external tree(s) that contains
FLOSS packages, leaving aside the br2-external tree(s) with the
proprietary bits.
What we do is to treat BR2_EXTERNAL as a colon-separated (space-
separated also work, and we use that internally) list of paths, on which
we iterate to construct:
- the list of all br2-external names, BR2_EXTERNAL_NAMES,
- the per-br2-external tree BR2_EXTERNAL_$(NAME) variables, which
point each to the actual location of the corresponding tree,
- the list of paths to all the external.mk files, BR2_EXTERNAL_MKS,
- the space-separated list of absolute paths to the external trees,
BR2_EXTERNAL_DIRS.
Once we have all those variables, we replace references to BR2_EXTERNAL
with either one of those.
This cascades into how we display the list of defconfigs, so that it is
easy to see what br2-external tree provides what defconfigs. As
suggested by Arnout, tweak the comment from "User-provided configs" to
"External configs", on the assumption that some br2-external trees could
be provided by vendors, so not necessarily user-provided. Ditto the menu
in Kconfig, changed from "User-provided options" to "External options".
Now, when more than one br2-external tree is used, each gets its own
sub-menu in the "User-provided options" menu. The sub-menu is labelled
with that br2-external tree's name and the sub-menu's first item is a
comment with the path to that br2-external tree.
If there's only one br2-external tree, then there is no sub-menu; there
is a single comment that contains the name and path to the br2-external
tree.

Config.in, external.mk and the new external.desc, instead of just
hinting about them in the external package recipes section.
Change the examples to use the NAME-suffixed variable instead of the

This unique NAME is used to construct a per br2-external tree variable,
BR2_EXTERNAL_$(NAME)_PATH, which contains the path to the br2-external
tree.
This variable is available both from Kconfig (set in the Kconfig
snippet) and from the .mk files.
Also, display the NAME and its path as a comment in the menuconfig.
This will ultimately allow us to support multiple br2-external trees at
once, with that NAME (and thus BR2_EXTERNAL_$(NAME)) uniquely defining
which br2-external tree is being used.
The obvious outcome is that BR2_EXTERNAL should now no longer be used to
refer to the files in the br2-external tree; that location is now known
from the BR2_EXTERNAL_$(NAME)_PATH variable instead. This means we no
longer need to expose, and must stop from from exposing BR2_EXTERNAL as
a Kconfig variable.
Finally, this also fixes a latent bug in the pkg-generic infra, where we
would so far always refer to BR2_EXTERNAL (even if not set) to filter
the names of packages (to decide whether they are a bootloader, a
toolchain or a simple package).
Note: since the variables in the Makefile and in Kconfig are named the
same, the one we computed early on in the Makefile will be overridden by
the one in .config when we have it. Thus, even though they are set to
the same raw value, the one from .config is quoted and, being included
later in the Makefile, will take precedence, so we just re-include the
generated Makefile fragment a third time before includeing the
br2-external's Makefiles. That's unfortunate, but there is no easy way
around that as we do want the two variables to be named the same in
Makefile and Kconfig (and we can't ask the user to un-quote that variable
himself either), hence this little dirty triple-inclusion trick.

Currently, we treat the case where we have no br2-external tree
(BR2_EXTERNAL is empty) differently from the case where we do have one
(BR2_EXTERNAL is not empty).
There is now no reason to treat those two cases differently:
- the kconfig snippet is always generated appropriately (i.e. it would
include the br2-external tree if set, or include nothing otherwise);
- we no longer have a dummy br-external tree either.
Also, the Makefile code to handle BR2_EXTERNAL is currently quite
readable if at least a little bit tricky.
However, when we're going to add support for using multiple br2-external
trees simultaneously, this code would need to get much, much more complex.
To keep the Makefile (rather) simple, offload all of the handling of
BR2_EXTERNAL to the recently added br2-external helper script.
However, because of Makefiles idiosyncracies, we can't use a rule to
generate that Makefile fragment.
Instead, we use $(shell ...) to call the helper script, and include the
fragment twice: once before the $(shell ...) so we can grab a previously
defined BR2_EXTERNAL value, a second time to use the one passed on the
command line, if any.
Furthermore, we can't error out (e.g. on non-existent br2-external tree)
directly from the fragment or we'd get that error on subsequent calls,
with no chance to override it even from command line.
Instead, we use a variable in which we store the error, set it to empty
before the second inclusion, so that only the one newly generated, if
any, is taken into account.
Since we know the script will always be called from Makefile context
first, we know validation will occur in Makefile context first. So we
can assume that, if there is an error, it will be detected in Makefile
context. Consequently, if the script is called to generate the kconfig
fragment, validation has already occured, and there should be no error.
So we change the error function to generate Makefile code, so that
errors are caught as explained above.
Lastly, when the value of BR2_EXTERNAL changes, we want to 'forget'
about the previous value of the BR2_EXTERNAL_MK variable, especially in
the case where BR2_EXTERNAL is now set to empty, so that we do not try
to include it later. That's why we first generate empty version of
BR2_EXTERNAL_MK, and then assign it the new value, if any.

Now that we generate a kconfig snippet, we can conditionally include the
BR2_EXTERNAL's Config.in only when BR2_EXTERNAL is supplied by the user,
which means our empty/dummy Config.in is no needed.
As for external.mk, we can also include it only when BR2_EXTERNAL is
supplied by the user, which means our empty/dummy external.mk is no
longer needed.
Ditch both of those files, and:
- only generate actual content in the Kconfig snippet when we actually
do have a BR2_EXTERNAL provided by the user (i.e. BR2_EXTERNAL is not
empty);
- add a variable that contains the path to the external.mk provided by
the user, or empty if none, and include the path set in that variable
(make can 'include' nothing without any problem! ;-) )

Move the inclusion of br2-external's Config.in to the generated kconfig
snippet.
This will ultimately allow us to use more than one br2-external tree.
Offload the "User-provided options" menu to the generated Kconfig
snippet. We can also move the definition of the Kconfig-version of
BR2_EXTERNAL into this snippet.
We introduce an extra check that was not present in the previous code,
to check that we do have permission on that directory. Prevciously, it
was handled as a side effect of not being able to cd into there, but it
is cleaner to check it expressly.

The BR2_DEPRECATED logic is a lot less useful than the legacy handling,
because the symbols just disappears without warning to the user. For
example, we had a few defconfigs that were using deprecated symbols
(which were not actually used because BR2_DEPRECATED wasn't set) so
these didn't build the expected code anymore.
Also, the idea behind BR2_DEPRECATED is that you can easily revive it
again if there is interest. However, it is relatively easy to revert
the removal of a package as well.
The deprecation is also more effort because it has to be removed twice:
once when deprecating, and once when really removing.
It doesn't make sense to add a legacy entry for BR2_DEPRECATED. Users
who actually used it will get legacy warnings instead.

Kodi segfaults as soon as it tries to load a python module:
Could not find platform independent libraries <prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
ImportError: No module named site
Segmentation fault
Turns out that keeping .py modules (with or without .pyc) fixes the
issue.
Currently, Kodi selects python, but since the format of modules is a
choice, we can not select it.
Fix that by inverting the dependency on python from Kodi:
- turn it into a depends rather than a select,
- add the dependency to ! pyc-only
- update the comment accordingly.
In addition, the !MMU and !static dependencies are updated since they
are no longer needed for Python (we now depend on it rather than
selecting it), but for other packages. The !MMU dependency is moved to
the _ARCH_SUPPORTS symbol as well.
Also, we can no longer "select BR2_PACKAGE_SAMBA4", because samba4
selects python, and we can no longer select python. Therefore, we switch
to a "depends on" dependency for samba4, which is fine as a user willing
to use Kodi with Samba will certainly realize that Samba should be
enabled.
Fixes bug #9221.
