It might just be that we didn't see it yet; either on daemon startup on in a
race. The nm_platform_*_add() deals with the device already being there in
_link_add_check_existing().

It is not uncommon to see first a "disown" message before "disposing".
That alone does not yet indicate anything wrong or a leak. Remove that
overly alarming part of the logging message.
Advantages:
- use current best-pratice
- registers a weak-ref to clear @singleton_instance when the
instance gets destroyed
- logs creation and destruction of singleton
- on shutdown, destroy the singleton instance via
_nm_singleton_instance_register_destruction(). Note, that
we now have yet another reference to the singleton that is
owned by register-destruction.
We already avoid loading duplicate plugins by checking find_plugin().
That iterates the plugins @list and checks for duplicate names.
Additionally, also reject duplicates based on the @plugins list.
Also, move the check for "keyfile" before, so that all explicit
checks for (statically) known names are early and together.
There is no need to have a static @singleton variable.
The only caller of nm_settings_keyfile_plugin_new() is
NMSettings which owns the singleton instance.
A *_new() function should just create a new instance and
that's it. It's unexpected to reuse the same instance.
Register the singleton instance of NMManager as we do for other
singletons. That way, we get automatic destruction and the singleton
instance get's properly cleared (when the instance gets destroyed).
Singletons that refer to other singletons in their destructor
should own a reference to those other singletons to ensure that
the lifetimes are handle correctly.
We want to create the platform instance rather late (especially after
claiming the D-Bus service). But we also want to destroy it very late,
because NMPlatform does not make use of any other singletons, but
other singletons make use of NMPlatform.
Some functions from nm-session-monitor.c have an implicit access to
nm_session_monitor_get(). This is non-obvious behavior.
Instead require the explicit session-monitor instance to be
provided -- where needed.
WiMAX support was dropped in commit 721e917cb6.
Also, remove support for the WiMAX rfkill flag and only preserve the
D-Bus property for backward compatibility.
We can dispose the manager before loading the factories:

All current users of NM_IN_SET() would rather use short-circuit evalation
(or don't care). It seems that doing it by default seems favorable.
The only downside is, that this might have somewhat unexpected behavior
to a user who expects a regular function (which would evaluate always
all arguments).

The config-tests contain a NMTestDevice which derives from NMDevice.
However, for testing, it just skips the constructor and destructor of
NMDevice. This caused also the destructors of NMExportedObject to be skipped
and thus valgrind complained about leaked memory.

Calling ethtool on a non-existing interface name, might cause
the loading of a kernel module. Avoid that, by checking first
whether such an interface exists.
https://bugzilla.redhat.com/show_bug.cgi?id=1247156
ethtool may cause the auto-loading of a kernel module for non-existing
interface-names. Avoid that by checking whether such an interface exists.
This is inherently racy.
Performing an ioctl on a non existent device may cause the automatic
load of a kernel module if the device name matches a module
alias. Check if the device actually exists before calling the ioctl.
For delete-events, we only need a shallow object with the key fields
set. That sufficies to lookup in the cache and find the object to
delete.
One other issue is that _nmp_vt_cmd_plobj_init_from_nl_link() and
link_extract_type() might call to ethtool for the already deleted
instance. Just avoid that.

Move the check for a platform link before devtimeout_from_file(). The
check in the platform cache should be more performant and yield success
in most cases.
This can save reading and parsing the ifcfg-rh file.
If NIC related initialization takes a long time in udev processing, but we have
an ifindex from kernel, we still want to wait until udev is finished and the
device is really usable.
Check that by calling nm_platform_link_get_by_ifname() and checking @initialized,
which means udev is finished.

Port the remaining parts of src/ to gdbus.
(Note that most of the individual commits on this branch do not
compile; they are split up for ease of comprehension, but all depend
on each other.)
https://bugzilla.gnome.org/show_bug.cgi?id=622927
Add --without-libnm-glib, for people who don't want to build the
legacy client libraries. When building with this option, dbus-glib and
libdbus are not required.
Port remaining bits to gdbus and remove stray dbus-glib references
Drop the dbus-glib version check from configure, since nothing depends
on new dbus-glib any more.
Move nm-dbus-glib-types.h and nm-gvaluearray-compat.h from include/ to
libnm-util/ since they are now only used by libnm-util and libnm-glib.
