Sometimes these function may set errno to unexpected values like EAGAIN.
This causes confusion. Avoid that by using our own wrappers that retry
in that case. For example, in rhbz#1797915 we have failures like:
errno = 0;
v = g_ascii_strtoll ("10", 0, &end);
if (errno != 0)
g_assert_not_reached ();
as g_ascii_strtoll() would return 10, but also set errno to EAGAIN.
Work around that by using wrapper functions that retry. This certainly
should be fixed in glib (or glibc), but the issues are severe enough to
warrant a workaround.
Note that our workarounds are very defensive. We only retry 2 times, if
we get an unexpected errno value. This is in the hope to recover from
a spurious EAGAIN. It won't recover from other errors.

Commit b2a0738765 ('man: improve manual page for nm-online') removed
the explanation of how may-fail can be used to wait for a specific
address family during boot. I found that part useful.
Note: this branch doesn't have commit 1e5206414a ('device: don't
delay startup complete for pending-actions "autoconf", "dhcp4" and
"dhcp6"') and so the text is different from branch nm-1-22 and later.

Fail the enslavement of the ovs port if the bridge device is not

The previous code tried to get the bridge active connection and it
used the port active connection instead in case of failure. This
doesn't seem right, as in nm-ovsdb.c the bridge AC is used to get the
bridge settings (including the uuid, interface name, and cloned mac).
In case of failure getting the bridge AC we should just fail.

With `./configure --enable-more-asserts`, we add extra -W flags to
AM_CFLAGS. This variable is only used, if the per-library override
libnm_core_libnm_core_la_CFLAGS is unspecified ([1]).
Usually we avoid this problem be never specifying library_CFLAGS, but
placing all our per-library flags to library_CPPFLAGS. While that is a
bit of a hack and misuse of CPPFLAGS, it works well (enough).
This was broken recently. The effect was, that libnm-core was not
build with AM_CFLAGS flags. Fix it.

(cherry picked from commit 9430c693fe)
Since commit c1907a218a ('libnm-core: remove gateway when
never-default=yes in NMSettingIPConfig'), the gateway gets normalized
away when the profile has never-default set.
That means,
$ nmcli connection modify "$PROFILE" ipv4.never-default yes ipv4.gateway 192.168.77.1
does not set the gateway. Likewise, if your profile has already never-default
enabled,
$ nmcli connection modify "$PROFILE" ipv4.gateway 192.168.77.1
will have no effect. That is confusing and undesirable.
Note that we don't adjust the GObject property setter for "gateway" to clear
never-default. I feel, setting one property in libnm should preferably
not unset another (there are exceptions to the rule, like for team
properties). However, for nmcli it's clear in which order properties
are set, so this change is right for the client tool.

On newer versions, the test binaries where renamed so that meson and
autotools build the same executables. Hence, the workaround for
valgrind warnings works on newer versions, but not on this branch.
Instead of backporting the renaming of the build artefacts, adjust
the test runner to work with meson builds.
Surisingly, the compiler may detect the remaining obj_type in
the default switch. Then, inlining nmp_class_from_type() it may detect
that this is only possible to hit with an out or range access to
_nmp_classes array.
Rework the code to avoid that compiler warning. It's either way not
supposed to happen.
Also, drop the default switch case and explicitly list the enum values.
Otherwise it is error prone to forget a switch case.

The client tests compare the test output with a .expected file that is
commit to git and that contains the expected output.
The expected output contains data like
size: 395
location: clients/tests/test-client.py:842:test_001()/1
cmd: $NMCLI
lang: C
returncode: 0
stdout: 277 bytes
>>>
...
Note that there is the line number (clients/tests/test-client.py:842) of
the source code where nmcli is called. This is to help correlate the output
with the test code.
However, Python 3.8 changes behavior and for function calls that span multiple
lines, frame.f_lineno will give now the starting line (previously, it gave the last
line) (see [1]).
No longer include the line number, as it is not stable accross Python versions.
If you really care, you can set NM_TEST_WITH_LINENO to get the line numbers back.
Of course, then the expected output won't match anymore, and you'd have to regenerate
it first. This is only useful if you debug tests, and want to have it easier to
correlate output with the tests while developing them.

Building with GCC 10 gives the following error:
multiple definition of_nm_jansson_json_object_iter_key';
libnm/.libs/liblibnm.a(libnm_core_la-nm-json.o):/builddir/build/BUILD/NetworkManager-1.23.1/libnm-core/nm-json.c:24: first defined here /usr/bin/ld:
libnm/.libs/liblibnm.a(libnm_core_la-nm-team-utils.o):/usr/include/jansson.h:202: multiple definition of _nm_jansson_json_object_iter';
This happens because GCC 10 defaults to -fno-common and so multiple
definitions of the same global variable are not merged together.
_nm_jansson_json_* symbols are defined in nm-json.c as void pointers
and, due to the following macros in nm-json.h:
#define json_object_iter_next (*_nm_jansson_json_object_iter_next)
...
the function declaration in jansson.h:
void *json_object_iter_next(json_t *object, void *iter);
becomes a global variable as well:
void *(*_nm_jansson_json_object_iter_next)(json_t *object, void *iter);
So, the symbol is present in nm-json.o and all other object files that
include nm-json.h, and -fcommon is required. Without it, it would be
necessary to define the symbols only in one place (for example,
nm-json.c), but then static inline functions from the jannson.h header
would still refer to the original (missing) jansson functions.
For the moment, just use -fcommon.

Meson 0.54.0 requires ninja-1.7 ([1]).
On Ubuntu 16.04, we now would get meson 0.54.0 via pip3, but ninja-1.5.1 via
apt. That doesn't work anymore.
We could install ninja via pip3, but of course, doing that on other
Debian/Ubuntu versions fails due to ... I don't even want to know.
So, instead use an old meson version on Ubuntu 16.04, which is
known to still work with the ninja provided by the packaging system.
We anyway don't want to test the same meson/ninja versions on all our
Ubuntu/Debian images. The point of having different images is to build
with different software versions. If `pip3 install` gives us the same
everywhere, it isn't very useful.
