Completely rework IP configuration in the daemon. Use NML3Cfg as layer 3
manager for the IP configuration of an interface. Use NML3ConfigData as
pieces of configuration that the various components collect and
configure. NMDevice is managing most of the IP configuration at a higher
level, that is, it starts DHCP and other IP methods. Rework the state
handling there.
This is a huge rework of how NetworkManager daemon handles IP
configuration. Some fallout is to be expected.
It appears the patch deletes many lines of code. That is not accurate, because
you also have to count the files `src/core/nm-l3*`, which were unused previously.

valgrind might log warnings about syscalls that it doesn't implement.
When we run valgrind tests, we check that the command exits with
success, but we also check that there is no unexpected content in the
valgrind log.
Those warnings are not relevant for us. We don't unit-tests valgrind, we
unit tests NetworkManager. Let's always remove such warnings with `sed`.
We already did that previously, but only for a explicit list of tests.
Now do it for all tests.
This is currently relevant on Fedora 35 and Ubuntu devel, where the
"close_range" syscall is used by libc, but not supported by valgrind.
While at it, rework the confusing logic of "HAS_ERRORS" variable.
Coverity warns about this:

The same code is executed regardless of whether "temp.index(subelement) < len(temp) - 1" is
true, because the then and else branches are identical. Should one of the branches be modified,
or the entire 'if' statement replaced?

Better fix for https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/732
The original issue was that when compiling NetworkManager with slibtool
the create-exports-NetworkManager.sh script gave the NetworkManager-all-sym
slibtool wrapper script to nm(1) instead of the actual binary. This is
because slibtool and GNU libtool do not place the compiled programs in
the same location. The original fix was to test both locations, but this
is bit of a hack especially since the build system should not be using the
.libs directory directly. However with $(LIBTOOL) --mode=execute this is
not a problem since both implementations can figure out where the correct
binary is.

"libnm-core/" is rather complicated. It provides a static library that
is linked into libnm.so and NetworkManager. It also contains public
headers (like "nm-setting.h") which are part of public libnm API.
Then we have helper libraries ("libnm-core/nm-libnm-core-*/") which
only rely on public API of libnm-core, but are themself static
libraries that can be used by anybody who uses libnm-core. And
"libnm-core/nm-libnm-core-intern" is used by libnm-core itself.
Move "libnm-core/" to "src/". But also split it in different
directories so that they have a clearer purpose.
The goal is to have a flat directory hierarchy. The "src/libnm-core*/"
directories correspond to the different modules (static libraries and set
of headers that we have). We have different kinds of such modules because
of how we combine various code together. The directory layout now reflects
this.
"shared/nm-meta-setting.[hc]" contains meta data about settings.
As such it is similarly used by libnm-core (as internal API) and
by clients (as extension of public API of libnm). However, it must
be compiled twice, because while it defines in both cases a
NMMetaSettingInfo type, these types are different between internal and
public API.
Hence, the files must also be compiled twice (and differently), once
against libnm-core and once against the client helper library.
Previously, the file was under "shared/", but there it's a bit odd
it doesn't clearly belong anywhere.
There are two goals here:
- copy the file to the two places where it is used. We also have
a "check-tree" unit test that ensures those files don't diverge in
the future.
- we no longer require CFLAGS set during built. Instead, the sources
should control the build. For that we have new (simple) headers
"nm-meta-setting-base.h" that define the right behavior for the
impl files.
There is still an ugliness (among several): the files must be named the
same for libnm-core and clients/common. Preferably, all our sources have
unique names, but that is not possible with this scheme (without
introducing other ugliness). To mitigate that, include the files only at
one exact place.
Our source tree also has certain consistency requirements. Since the
source is in git, this is a rather static check. However, we want to
ensure that future changes don't break it by adding a test.
Currently "src/" mostly contains the source code of the daemon.
I say mostly, because that is not true, there are also the device,
settings, wwan, ppp plugins, the initrd generator, the pppd and dhcp
helper, and probably more.
Also we have source code under libnm-core/, libnm/, clients/, and
shared/ directories. That is all confusing.
We should have one "src" directory, that contains subdirectories. Those
subdirectories should contain individual parts (libraries or
applications), that possibly have dependencies on other subdirectories.
There should be a flat hierarchy of directories under src/, which
contains individual modules.
As the name "src/" is already taken, that prevents any sensible
restructuring of the code.
As a first step, move "src/" to "src/core/". This gives space to
reorganize the code better by moving individual components into "src/".
For inspiration, look at systemd's "src/" directory.

When "tools/run-nm-test.sh" is called from the build scripts,
it has as first argument "--called-from-make". Then all arguments
must follow in a well defined order, which autotools/meson understand
and follow.
Another main use is however to call "tools/run-nm-test.sh" form the command
line. In that case, we want to have the command line parsing convenient.
Some of the parameters to the script are interpreted by the script, and
some are passed on to the test. The user can use "--" to separate the
parameters:
./tools/run-nm-test.sh -m shared/nm-glib-aux/tests/test-shared-general -- -p /general/test_strv_cmp
Otherwise, on the first unknown argument "tools/run-nm-test.sh" would
assume all following arguments are for the test. So this worked too:
./tools/run-nm-test.sh -m shared/nm-glib-aux/tests/test-shared-general -p /general/test_strv_cmp
However, if you now want to run the test with valgrind, you need to edit
the command line before the test arguments, like
./tools/run-nm-test.sh -m shared/nm-glib-aux/tests/test-shared-general -v -p /general/test_strv_cmp
That is inconvenient because I call the script from the shell history and
the cursor is at the end of the line. Instead, assume that all unknown parameters
are for the test (until "--" is encountered).
Now this works:
./tools/run-nm-test.sh -m shared/nm-glib-aux/tests/test-shared-general -p /general/test_strv_cmp -v
Arguably, now also
./tools/run-nm-test.sh -m shared/nm-glib-aux/tests/test-shared-general -p -v /general/test_strv_cmp
works, which is a bid odd.
The previous implementation would print
./tools/check-gitlab-ci.sh: line 22: ci-fairy: command not found
also, it's not nice to execute the program, just to find out whether
we have it.
This will be used on our gitlab-ci tests. We do have a separate,
dedicated test on gitlab-ci for checking that "gitlab-ci.yml" is
correct.
We may intentionally want to violate that condition, but then our
`make check` should not fail.
Add a way to skip that test.
If there are multiple NM_CON_DEFAULT() mentionings on the same line,
previously the script would not parse them all. Adjust, by first wrapping
the line.
