425a1e9f20 docs/manual: add allowed notations section for genimage.cfg files
Add allowed notations section for genimage.cfg files by specifying the
accepted suffix or prefix. Note that "K" has been decided to specify
KiloBytes as 1024 bytes. This has been done because in Buildroot the 90%
of the cases were using "K" and not "k".

a9dc2de551 docs/manual/contribute.txt: rewrite the section dedicated to runtime tests
The current documentation was poorly organized, with for example the
"Here is an example walk through of running a test case" sentence
followed by the explanation of how to list available test cases, but
not how to run one.

Many other aspects of the wording were confusing, or not really
accurate.

23186356a1 support/scripts/generate-gitlab-ci-yml: allow multiple tests in one pipeline
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

to run all Busybox tests.

e1ee121cae docs/manual/using-buildroot-debugger: suggest '-ix' iso '-x' when loading gdbinit
A gdbinit file passed via '-x' will be read _after_ parsing any
object/core file passed on the command-line. In cross-compilation context,
this is particularly a problem when loading a core file, because without the
'sysroot' specified in the gdbinit file, it will give a lot of warnings,
like:

    warning: .dynamic section for "/lib/libstdc++.so.6" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/lib/librt.so.1" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/lib/libm.so.6" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/lib/libgcc_s.so.1" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/lib/libc.so.6" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/lib/ld-linux.so.2" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/lib/libanl.so.1" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/lib/libdl.so.2" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/lib/libpthread.so.0" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/usr/lib/libz.so.1" is not at the expected address (wrong library or version mismatch?)
    warning: .dynamic section for "/lib/libnss_files.so.2" is not at the expected address (wrong library or version mismatch?)

    warning: Could not load shared library symbols for 17 libraries, e.g. [...]
    Use the "info sharedlibrary" command to see the complete listing.
    Do you need "set solib-search-path" or "set sysroot"?

In contrast, the '-ix' option will load the specified gdbinit file _before_
parsing object/core files. This will remove said warnings.

c7d71b707d package/pkg-kconfig: generate generic help
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.

61c5e0319c package/pkg-cmake.mk: determine CMAKE_BUILD_TYPE depending on BR2_ENABLE_RUNTIME_DEBUG
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.

fe3cb7978a docs: move the IRC channel away from Freenode
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.
