Currently it is always required to add package version as an argument to
the github helper. Since the version is always defined as PKG_VERSION,
drop this argument and generate it automatically inside the helper
routine.
The github helper function is extended to support both 2 and 3 argument
variants (ie. either use the provided package version argument or
automatically substitute with PKG_VERSION if not available), which can
make the transition of the package files easier as well allows using the
3-argument variant outside of package definitions.

When we have multiple versions for a package, and the licensing terms
depend on the version actually selected (e.g. like Qt5), storing the
hashes for those license files in the .hash file is broken: the infra
will ensure that all hashes for a file do match, which would not be the
case here.
We fix that by first looking for a hash file in the version sub-dir
first, and if that does not exist, then we use the main hash file.
Drop the useless intermediate variable 'ret'.
Update the documentation accordingly.

Make inclusion ordering of all linux-tool-*.mk sub-makefiles explicit
instead of relying on alphabetical sort order. This is done by
renaming the Linux tools sub-makefiles to the format linux-tool-*.mk.in.
This causes the top-level Makefile to ignore the Linux tools
sub-makefiles.
Until now, the main Makefile included all linux-tool-*.mk files, as
well as linux-tools.mk, and it relied on alphabetical sorting to
include them in the proper order (linux-tool-*.mk before
linux-tools.mk).

- We are now checking hashes for Git downloaded packages, so fix this

- We no longer want to have auto-generated patches be downloaded

Currently, the output of printvars copntains the name of the variable,
its expanded value and its un-expanded value.
However, most of the time, we need the actual, expanded value, so it can
be re-used from a (non-Buildroot) infrastructure script, like a
post-build script, or a build-farm driver (e.g. a Jenkins job...)
Add two options that a user may set to change the output of printvars:
- QUOTED_VARS, if set, will quote the value
- RAW_VARS, if set, will print the unexpanded value
The new output by default only prints the expanded value now.
So that it can be used as such:
$ make -s printvars VARS=BUSYBOX_VERSION
BUSYBOX_VERSION=1.26.2
$ make -s printvars VARS=BUSYBOX_RDEPENDENCIES QUOTED_VARS=YES
BUSYBOX_RDEPENDENCIES='ncurses util-linux'
$ make -s printvars VARS=BUSYBOX_FINAL_PATCH_DEPENDENCIES RAW_VARS=YES
BUSYBOX_FINAL_PATCH_DEPENDENCIES=$(sort $(BUSYBOX_PATCH_DEPENDENCIES))
And it is even possible to directly evaluate it in a shell script:
eval $(make -s printvars VARS=BUSYBOX_VERSION QUOTED_VARS=YES)
Backward compatibility of the output is not maintained. It is believed
that scripts that depended on the previous output were very fragile to
begin with, because they had to filter the non-formatted output
(splitting on spaces or braces was not really possible, because values
could contain either).
Document printvars and its options in the manual; list it in the output
of 'make help'.

Recently, the autoconf macros for libtool started using '/usr/bin/file'
to determine the type of library that is generated by the toolchain.
Packages that use this recent version of the libtool autoconf macros
will fail in a rather dramatic way when /usr/bin/file is not present
on the host: the package will still build but no shared library is
generated, which in turn may cause build failures in other packages
that link with it.
For example, libpng's configure determines that it is not possible to
build a shared library on MIPS64 because the expected output from 'file'
is not present. Therefore, only a static libpng.a is built. Later,
bandwithd links with -lpng but it doesn't use the pkg-config's
Private-Libs (because it's not linking statically) and it doesn't have
access to the NEEDED reference from the shared library. Therefore, it
doesn't link with zlib and fails with
pngrutil.c:(.text+0x55c): undefined reference to `inflate'
We cant use host-file because it is itself an autotools package and is
itself using libtool, so this would be a chicken-n-egg problem. Besides,
the libtool script really wants to call /usr/bin/file, so it would not
even find our host-file anyway.
So, just require that '/usr/bin/file' is present on the host.

Currently, it is not possible for a br2-external tree to override a
defconfig bundled in Buildroot, nor is it possible to override one from
a previous br2-external tree in the stack.
However, it is interesting that a latter br2-external tree be able to
override a defconfig:
- the ones bundled in Buildroot are minimalist, and almost always
build a toolchain, so a br2-external tree may want to provide a
"better" defconfig (better, in the sense "suited for the project");
- similarly for a defconfig from a previous br2-external tree.
But we can't do that, as the rules for the defconfigs are generated in
the order the br2-external trees are specified, all after the bundled
defconfigs. Those rule are patten-matching rules, which means that the
first one to match is used, and the following ones are ignored.
Add a new utility macro, 'reverse', inspired from GMSL, that does what
it says: reverse a list of words.
Use that macro to reverse the list of br2-external trees, so that the
latters win over the formers, and even over bundled ones.

Currently, a document can not have dependencies, except for the purely
internal ones (like checking asciidoc version, and presence of dblatex).
For our own manual, this will come in handy when we introduce a
generated kconfig snippet, so we can actually make the manual depend on
that snippet being generated first.
For external documents, it can be used to depend on host-packages if
need be (e.g. a custom host packages that generates specific media files
included in the manual).

In order to avoid this potential mistake, this commit introduces a

When using a br2-external tree, it is possible (as stated in our manual)
to implement whatever arbitrary extra make rules (such as flashing a
board, or extracting the rootfs in an NFS export...). Some of those
extra rules might be exposed to the user as new entry points that the
user can call by itself.
However, there is no way for the br2-external to advertise those new
rules in the help text.
We add the possibility to do so, by adding a new make rule, called
help-custom, advertised in our own help info.
It is up to the br2-external tree to provide whatever help text is
deemed necessary. The format of the help is completely free-form.
Note that we need to provide an empty, dummy help-custom rule, since it
is always advertised (making it .PHONY does not work). Since this rule
is empty, make gently reports that there is "Nothing to be done for
`help-local'", which is pretty well fitting when help-local was not
provided (either because there's no br2-external tree, or when the
br2-external tree does not provide it.

Leverage the CSV files produces by size-stats (make graph-size) to allow
for a comparison of rootfs size between two different buildroot
compilations.
The script takes the file-size CSV files of two compilations as input, and

Using the -d/--detail flag, the report will show the file size changes
instead of package size changes.
The -t/--threshold option allows to ignore file size differences smaller

Currently, we forcibly override BR2_EXTERNAL when building the manual,
so as to avoid referring to packages therein from the manual.
However, when generating the lists of packages, we limit ourselves to
scanning for packages in (Buildroot's) TOPDIR and never search in
BR2_EXTERNAL. So, we do not really need to override BR2_EXTERNAL when
generating the manual to achieve the same result.
Furthermore, we're only looking for packages that are defined in the
sub-menu "Target packages", and never anywhere else, and especially not
in the sub-menu "User-provided options".
Finally, we're soon to completely eliminate use of BR2_EXTERNAL in
Kconfig altogether, so that would no longer have any impact anyway.
So, just leave BR2_EXTERNAL alone when generating the manual.

When building in a different output directory than the original build,
there will currently be a lot of ccache misses because in many cases
there is some -I/... absolute path in the compilation. Ccache has an
option CCACHE_BASEDIR to substitute absolute paths with relative paths,
so they wil be the same in the hash (and in the output).
Since there are some disadvantages to this path rewriting, it is made
optional as BR2_CCACHE_USE_BASEDIR. It defaults to y because the
usefulness of ccache is severely reduced without this option.
In addition to CCACHE_BASEDIR, we also substitute away the occurences
of $(HOST_DIR) in the calculation of the compiler hash. This is done
regardless of the setting of BR2_CCACHE_USE_BASEDIR because it's
quite harmless.

Because of a limitation in how makedevs resolves names [0], usernames
and groupnames would be resolved with UIDs and GIDs from the host, not
the target.
Fixing makedevs would involve us rewriting a /etc/passwd and /etc/group
parser (not too complex, still not trivial).
Document that the user and group fields should only be numbers, not
names. Also, the manual is currently misleading, as an example indeed
uses names for the user and group fields. Fix that and expand the
explanations.
The mode field should also be numbers, not a rwx combo.
Slight typographical eye-candy about major/minor fields.

Those issues were noticed by Thomas De Schampheleire during the
review, but they were forgotten when applying the patch.

The following allows a user definition to specify that a created user
entry should not have a password value set. Original implementation
allowed a user definition to provide a password value of "=" (no quotes)
to generate a crypt-encoded empty string value. In some cases, it may be
desired to have no value specified for a user's password. By using a
value "-" for a password, no value will be set in the shadow value.
An example when this can be used is when logging into a terminal.
Logging into a session with an encoded empty password will prompt a user
to enter a password since it does not know the password is empty. If the
password field blank, a login session will not prompt for a password.

They are not needed, and other code blocks in the same file are not
indented either.
Remove those leading spaces, so all our code blocks look the same.

Adds functionality to the kconfig infrastructure to merge additional
configuration fragment files to the main configuration file of
kconfig packages, using support/kconfig/merge_config.sh
Typical use-case is when you want your configuration to be
kept in sync with an upstream (def)config file, but do require
some minor local modifications.
Disables -update-config and -update-defconfig targets when
fragment files are set.
[Thomas: take into account comments made by Arnout:
- Minor fixes in the documentation changes
- Add @ before the tests done in the $(1)-update-config and
$(1)-update-defconfig targets.]

The names of steps are not obvious, so add this list to the manual.
Small formatting fix at the same time.

We can't take hashes from GitHub, unless the tarball has been uploaded by
the maintainer, otherwise it is generated and may change over time,
which renders hash files useless.

We accept an md5 hash, but only if coming from upstream, and if also
accompanied with a stronger hash.

Commit 53903a15 (*config: improve handling of BR2_LEGACY) added an
option to entirely skip legacy entries, by passing a variable in the
environment.
However, it missed one location where that variable is also needed,
which is generating the list of packages and deprecated features for
inclusion in the manual.
Fix that by re-using the global $(COMMON_CONFIG_ENV) variable,
overriding just what we don't want (i.e. br2-external location and
defconfig path).
Also, slightly re-order variables so the ones we override come right
after the common settings, moving the specific ones at the end, one
variable per line.
