NMSettingWirelessWakeOnWLan is public API of libnm/libnm-core
in "src/libnm-core-public/"
We want that libnm-platform is independet of libnm-core to keep
the dependencies smaller and code better separated. Hence we
cannot use that enum there.
Duplicate NMSettingWirelessWakeOnWLan as _NMSettingWirelessWakeOnWLan
in libnm-base.
Avoid dependencies but explicitly link the static library where it is
used.
This also fixes that we linked libnm-log-core into
libnm-settings-plugin-ifcfg-rh.so, which duplicated the symbols
while it should used them from NetworkManager.
"nm-test-utils.h" is a header-only, helper library for our unit tests.
It was somewhat unmotivated in "shared/nm-utils", because all tests use
it, but it was not part of a "module".
Move it to "src/libnm-glib-aux/". It fits there very well. They both
have (only) a dependency on glib.
We want that there is a clear hierarchy and dependency between
modules/directories.
But tests sometimes break that.
For example, "shared/nm-glib-aux/tests" link against libnm-glib-aux
and libnm-log-null. But "shared/nm-log-null" depends on "shared/nm-glib-aux".
Hence, for the test there is a circular dependency.
Break that, by including all tests at the end.
The alternative would be ugly in different ways.
This is really just a different implementation of
"nm-glib-aux/nm-logging-fwd.h", that parallels libnm-log-core.
It's also not only useful to shared/systemd, but also share/nm-platform,
which also requires linking with a logging backend.
The bond option ad_actor_system only matters (and is available) with
mode=802.3ad.
When you create a new bond, the sysctl value will be set to "00:00:00:00:00:00".
So this seems to be a valid value, and in fact the default value for
this option. However, kernel will fail with EINVAL to set the sysctl to
"00:00:00:00:00:00". Kernel fails both if the value is already
"00:00:00:00:00:00" (i.e. setting the same value results in an error) and
it also fails otherwise (i.e. we cannot ever reset the value to
"00:00:00:00:00:00", at least not via sysfs).
Avoid the warning in the common case, where the value is already as
expected.
Otherwise, we still get the warning and won't be able to set the right
value. But this is really a limitation of the kernel API where we cannot
do anything about it (in NetworkManager).

glib requires G_LOG_DOMAIN defined so that log messages are labeled
to belong to NetworkManager or libnm.
However, we don't actually want to use glib logging. Our library libnm
MUST not log anything, because it spams the user's stdout/stderr.
Instead, a library must report notable events via its API. Note that
there is also LIBNM_CLIENT_DEBUG to explicitly enable debug logging,
but that doesn't use glib logging either.
Also, the daemon does not use glib logging instead it logs to syslog.
When run with `--debug`.
Hence, it's not useful for us to define different G_LOG_DOMAIN per
library/application, because none of our libraries/applications should
use glib logging.
It also gets slightly confusing, because we have the static library like
`src/libnm-core-impl`, which is both linked into `libnm` (the library)
and `NetworkManager` (the daemon). Which logging domain should they use?
Set the G_LOG_DOMAIN to "nm" everywhere. But no longer do it via `-D`
arguments to the compiler.

"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.
