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.
The documentation is updated accordingly.

Some qmake based packages need to call the syncqt.pl script before
building to have a properly populated "include" directory inside the
package build tree.
This script is normally automatically executed by qmake when a source
tree is from a git clone: buildroot purges the .git directory hence
the script never runs, and we need to call it explicitly. Setting
<pkg>_SYNC_QT_HEADERS = YES will force calling this script.

Currently, the linux kernel will apply some fixups on its .config file,
based on whether some packages are enabled or not. That list of
conditional fixups is getting bigger and bigger with each new package
that needs such fixups, culminating with the pending firewalld one [0].
Furthermore, these fixups are not accessible to packages in br2-external
trees.
Add a new per-package variable, that packages may set to the commands to
run to fixup the kernel .config file, which is added at the end of the
linux' own fixups.
This opens the possibility to write things like;
define FOO_LINUX_CONFIG_FIXUPS
$(call KCONFIG_ENABLE_OPT,BLA)
endef
Of course, it also opens the way to run arbitrary commands in there, but
any alternative that would be declarative only, such as a list of
options to enable or disable (as an example):
FOO_LINUX_CONFIG_FIXUPS = +BAR -FOO +BUZ="value"
.. is not very nice either, and such lists fall flat when a value would
have a space.
For packages that we have in-tree, we can ensure they won't play foul
with their _LINUX_CONFIG_FIXUPS. For packages in br2-external trees,
there's nothing we can do; users already have the opportunity to hack
into the linux configure process by providing LINUX_PRE_CONFIGURE_HOOKS
or LINUX_POST_CONFIGURE_HOOKS anyway...
.. which brings the question of why we don't use that to implement the
per-package fixups. We don't, because _PRE or _POST_CONFIGURE_HOOKS are
run after we run 'make oldconfig' to sanitise the mangled .config.

With autoconf packages, we often specify ac_cv_func_... cached values to
avoid runtime checks during configure. With meson the equivalent is
setting properties in cross-compilation.conf which we cannot do in
Buildroot at the moment.
For example, libglib2 used to set ac_cv_func_printf_unix98 and
ac_cv_func_vsnprintf_c99 so that the system printf could be used, but
with the conversion to meson these checks fail and the gnulib fallback
is used.
Add infrastructure in the same way as FOO_MESON_EXTRA_BINARIES to allow
per-package modification to the cross-compilation properties.

This provides generic functions for Qt5 qmake based packages. It will
make it possible to remove lots of redefinition of
QT5_xxx_{CONFIGURE|BUILD|INSTALL_STAGING}_CMDS. Additionally it
provides a generic target install method which will make most of the
package specific commands obsolete.
This is done by re-running the install step of the qmake generated
Makefile with the package build directory prepended (to the
staging/host path). Even though this does create lengthy pathes it
allows for easy separation of the staging files from the host destined
files by just omitting the resulting BUILD_DIR+HOST_DIR path from the
following rsync call to the real target folder. The cleanup of many
files we dont want in target is deferred to the target-finalize
step. In addition to what's being removed already, we also have to
cleanup some Qt5 specific files (prl) and the documentation directory.
This approach was chosen over copying all files recorded in the pkg-files-list
after some discussion which Thomas Petazzoni summed up:
"We don't yet use pkg-files-list really as part of the build
process anywhere, I feel a bit more comfortable at this point with what
Andreas is proposing."
Thanks to this infrastructure, it will be possible to get rid of the
many conditional install commands because qmake already takes care of
this when generating the Makefile install targets with the given or
autodetected configure options of each package.
However, custom install steps may have to remain in cases where a
particular Buildroot option has no corresponding setting in the
packages configuration options.
