Some software decides based on uid/gid whether a user is a system or
normal (human) user, with different behaviour for those flavors (example
journald [2]).
So adding logic to create system-users is necessary, we take the now
common ranges from [1].
This extends the mkusers script to allow -2 for uid/gid, this argument
will take an identifier from the user range. All identifiers used up to
now should have been from the system range, so -1 is now interpreted as
a system user/group.
Note that after this commit, all the UIDs and GIDs that are created
automatically (with -1) will change. That means if there is peristent
data on an existing system that was created by such an automatic user,
it will suddenly belong to a different user. However, this could already
happen before: if a USERS line is added to a package, then other UIDs
may change as well.
Add system/user ranges as variables, and the argument for user/system
uid variable as well. Thus some magic constants could be removed, some
further occurences of -1 were replaced with equivalent logic. For
consistency, the existing MIN/MAX_UID/GID variables are renamed to
FIRST/LAST_USER_UID/GID.
Update the documentation with the new automatic ranges.

Commit 1ba85b7f87 (support/download: add explicit no-hash support)
introduced the 'none' hash type, in an attempt to make hash files
mandatory, but not failing on archives localy generated, like those
for git or svn repositories, especially for those packages where a
version choice was present, which would allow for either remote
archives for which we'd have a hash or VCS trees for which we could
not have a hash for the localy generated archive.
Indeed, back in the time, we did not have a mean to generate
reproducible archives, so having a hash file without a hash for
thosel ocally generated archives would trigger an error in the
hash-checking machinery.
But now, low-and-behold, we do know how to generate those archives,
and we have a mechanism to explicitly exclude some archives from being
hash-checked (e.g. when the version string itself can be user-provided).
As such, the 'none' hash type no longer has any raison d'être, we do not
use it in-tree, and its use in a br2-external tree is most probably
inexistent (as is the use of hash files alotgether most probably).
So we simply drop the support for that.

The Buildroot manual was already providing some details on how to
integrate Cargo packages, and those details now need to be updated
with a proper documentation for the cargo-package infrastructure, as
well as updates related to vendoring support, which affects how
dependencies are handled.
In addition, now that we have vendoring support for Cargo packages,
let's rewrite the dependency management section in a more accurate
way.
We drop the part about the local cache of the registry, because
+CARGO_HOME+ in Buildroot points to $(HOST_DIR)/share/cargo, which is
not shared between builds nor preserved accross builds, so its effect

The current Gitlab CI mechanism allows to trigger all tests in a CI
pipeline by pushing a branch named <something>-runtime-tests, or to
trigger a single test in a CI pipeline by pushing a branch name
<something>-tests.<name of test>.
However, there are cases where it is useful to run a suite of tests,
for example to run all tests in tests.init.test_busybox.
This commit makes that possible by extending the current semantic of
<something>-tests.<name of test> to not expect a complete test name,
but instead to accept all tests that starts with the given pattern.
This allows to do:
git push gitlab HEAD:foobar-tests.init.test_busybox.TestInitSystemBusyboxRo
like it was the case before. But it now also allows to do:
git push gitlab HEAD:foobar-tests.init.test_busybox

A gdbinit file passed via '-x' will be read _after_ parsing any

this is particularly a problem when loading a core file, because without the

like:

warning: .dynamic section for "/lib/librt.so.1" is not at the expected address (wrong library or version mismatch?)

Do you need "set solib-search-path" or "set sysroot"?

Currently, as Thomas pointed out [0], the help for kconfig packages is
not consistently used and handled by the different packages.
This commit introduces a generic help text for kconfig packages, that is
based on what the package declares:
- the list of kconfig editors it supports;
- whether it is possible to save back the configuration (impossible if
the package uses an in-tree defconfig file);
- whether the package actually supports (loading and saving) defconfig
files, by introducing a new variable a package can set if it does
not (only busybox is known to be in that case).
That new help helper is only used if the package does not already define
its own help, to be consistent with what we do for other _CMDS.

The CMAKE_BUILD_TYPE is currently set as 'Debug' in case BR2_ENABLE_DEBUG is
set, and as 'Release' in other cases. However, while the description of
BR2_ENABLE_DEBUG is to enable debug symbols (no runtime impact), the 'Debug'
build type in CMake can actually have runtime impact. For one, because it
does not set -DNDEBUG like is done for 'Release', but also because packages
may do custom things based on it.
The question of which CMAKE_BUILD_TYPE Buildroot should set, be it 'Debug',
'Release', 'RelWithDebInfo' or others, has come up several times in the
past. See some references below:
- July 2016: switch from Debug to RelWithDebInfo:
https://git.buildroot.org/buildroot/commit/?id=4b0120183404913f7f7788ef4f0f6b51498ef363
- October 2016: switch from RelWithDebInfo back to Debug:
https://git.buildroot.org/buildroot/commit/?id=104bb29e0490bfb487e2e665448dd3ca07fcc2b5
and changes to make sure Buildroot's flags are respected:
https://git.buildroot.org/buildroot/commit/?id=12494ef48f893684d0800e7f6fe39a2ceaed0451
- August 2017: bug #10246 - "BR2_ENABLE_DEBUG does not have the expected
effect for cmake packages"
https://bugs.busybox.net/show_bug.cgi?id=10246
- August 2017: mail thread following bug #10246:
http://lists.busybox.net/pipermail/buildroot/2017-August/200778.html
In the last mail thread, Samuel Martin confirmed that the 'Release' build
type could be used in all cases, because Buildroot is actually making sure
that the optimization flags are those determined by Buildroot, not the
defaults of cmake, thanks to commit 12494ef48f.
But Arnout Vandecappelle objected to using always 'Release', stating that
users may actually want the extra assertions.
With the introduction of BR2_ENABLE_RUNTIME_DEBUG, Buildroot can now cater
for all cases:
- use CMAKE_BUILD_TYPE=Release by default. This makes sure that there is no
unexpected performance degradation triggered by enabling BR2_ENABLE_DEBUG.
- users can optionally enable BR2_ENABLE_RUNTIME_DEBUG if they want runtime
debug info like assertions, at the risk of introducing performance
degradation. In this case, we switch to CMAKE_BUILD_TYPE=Debug.
- orthogonally to the above, BR2_ENABLE_DEBUG still determines passing the
'-g' flag to enable debug symbols, and BR2_OPTIMIZE_X still determines the
used optimization flags.

Due to the recent events at Frenode [0], the channel has become a bit
unreliable (much spammed), and users have started to move away already,
as quite a few other projects have moved their IRC presence away from
Freenode.
There are a few alternatives. The first to spring to mind, is the new
Libera.Chat network [1], managed by the previous Freenode staff, so we
could expect quite a good experience there. However, it is a very young
network. The second well known alternative is the long-established OFTC,
which has been very reliable in its 20 years of existence.
So, let's move to OFTC, just because it has a track-record of robustness
(which Libera.Chat still has to build, for being young).
Note: there are a lot of other IRC networks, some very good too, but we
probably would be much off-topic on most of them.

Sometimes, post-build or post-image scripts need to reinvoke
Buildroot's make, for example to execute "make printvars".
However, so far post-build/image/fakeroot can't trivially run printvars
in a way that worked for both in-tree and out-of-tree builds. Indeed:
* "make printvars" would work for in-tree builds, but not out of tree
builds
* "make -C ${O} printvars" would work for out-of-tree builds, but not
in-tree builds
* "make -C ${BR2_CONFIG%/*} printvars" works in both cases, but it is
a bit cryptic, and two maintainers did not even immediately think of
it
In order to solve this, this commit exposes $(CONFIG_DIR) to
post-build/image/fakeroot scripts, through the EXTRA_ENV variable.

This script is normally automatically executed by qmake when a source

the script never runs, and we need to call it explicitly. Setting
