2114c29e91 Revert "pkg-download: remove explicit PKG_VERSION from github helper"
This reverts commit 1e5a8916b2.

The idea was that the version string can be derived because we know the
package name.

However, this patch does not account for the fact that $(pkgname) always
points to the latest pacakge scanned, which in all other situation we're
using it, is the current package, because it is used inside one ot he
xxx-inner macros that are $(eval)ualed. So $(pkgname) is evaluated
"early" and gets the expected value.

However, the github value is not in one of those macros, so it gets
evaluated "late", when doing the actual download. So, by that time,
$(pkgname) will expand to the last package scanned, which is actuall the
manual (without a br2-external tree).

That would require that the _SITE variable be assigned with the :=
assignment operator. This is weird, because that would make it the only
variable to require that, but only when using the github helper, which
is even less obvious and would cause a lot of trouble...

The obvious fixup would seem to be to use $(PKG) instead, because that
already contains the upper-case package name that vcan be used as a
prefix to variables.

However, that does not work either, because we have a check that forbids
a trsailing slash in _SITE, check that is done in pacakge/pkg-generic,
inside the xxx-inner macro, during the $(eval) call.

And at that time, PKG is not yet defined, because it is only defined for
an actual recipe.

So we can't seem to have a workable solution. So, just revert the patch.

1e5a8916b2 pkg-download: remove explicit PKG_VERSION from github helper
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.

63eeb9a383 core/legal-info: use hash file from version sub-dir
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.

b2c043b29a package/linux-tools: change method for including linux-tool sub-makefiles
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).

0611045c42 manual: patches are not applied for SITE_METHOD = local
We had several remarks on the mailing list of users that were surprised
that patches were not applied for packages whose SITE_METHOD is local.
So document this.

Note that for OVERRIDE_SRCDIR itself it is already documented:

  When Buildroot finds that for a given package, an
  <pkg>_OVERRIDE_SRCDIR has been defined, it will no longer attempt to
  download, extract and patch the package. Instead, it will directly use
  the source code available in in the specified directory.

a0c9b36b80 docs/manual: update details about hashes
This commit updates the manual about hashes, fixing a number of
issues:

 - Adding the .hash file should no longer be optional: it *must* be
   added. Therefore the wording "You can add ..." is changed to "When
   possible, you must add ...".

 - We are now checking hashes for Git downloaded packages, so fix this
   as well, and indicate more clearly which download methods have hash
   checking.

 - We no longer want to have auto-generated patches be downloaded
   through <pkg>_PATCH because such patches are not stable over time,
   and their hash can change. For example, downloading patches from
   github.com should no longer be done.

ba6360316f core: enhance printvars
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'.

75cf694bb0 luarocks-package: introduce PKG_NAME_UPSTREAM
Since we now require Lua package names to start with "lua", it is likely
that the Buildroot name is different from the upstream LuaRocks name.
Add a feature to the luarocks-package infra that makes it easier to
handle this situation: the package can explicitly specify the upstream
name in PKG_NAME_UPSTREAM, and that name will be used in PKG_ROCKSPEC,
PKG_SOURCE and PKG_SUBDIR.

Add an explanation of this feature to the manual. To make the example
relevant, it is changed to lua-foo, where the upstream name is plain
foo. To avoid confusion with the dependency on a native library, that
dependency is renamed to bar.

We currently have two places where we recommend where BR2_DL_DIR
should be set: "Environment variables" and "Location of downloaded
packages". The former recommends setting BR2_DL_DIR in the .config,
the latter kind of endorses using ~/.bashrc.

We prefer suggesting the ~/.bashrc way since it avoids downloading the
same file multiple times, and anyway it's wise to have all the details
in a unique place. So remove the .config suggestion from "Environment
variables" and let it just point to "Location of downloaded packages".

428145838b docs/manual: suggest 'YES' as the value for LIBFOO_GIT_SUBMODULES
The manual mentions LIBFOO_GIT_SUBMODULES but does not tell what value
it should have. The implementation only checks whether the variable is
non-empty, but we should suggest a specific value to avoid people
wondering what they have to set, and to try setting weird values.

e09e1873a1 support/dependencies: ensure we have 'file' on the host
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.
