43ee7c6db1 virgdbus: fix getting non-shared DBus connection
We need to pass some flags in order to properly initialize the
connection otherwise it will not work. This copies what GLib does
for g_bus_get_sync() internally.

This fixes an issue with LXC driver where libvirt was not able to
register any VM with machined.

3113f3d815 virGDBusBusInit: Properly check for error when looking up D-Bus address
The virGDBusBusInit is supposed to return a reference to
requested bus type (system/session) or, if non-shared bus is
requested then create a new bus of the type. As an argument, it
gets a double pointer to GError which is passed to all g_dbus_*()
calls which allocate it on failure. Pretty standard approach.
However, since it is a double pointer we must dereference the
first level to see if the value is NULL. IOW:

  if (*error)

784f204e7e util/virgdbus: fix memory leak in virGDBusIsServiceInList
g_variant_iter_loop() handles freeing all arguments unless we break out
of the loop, in that case we have to free them manually.

a961d93768 virgdbus: add DBus reply format check
We used to check the format of reply data with libdbus so we should do
the same with GLib DBus as well.

2ef84f000f util: introduce helpers for GLib DBus implementation
With libdbus our wrappers had a special syntax to create the DBus
messages by defining the DBus message signature followed by list
of arguments providing data based on the signature.

There will be no similar helper with GLib implementation as they
provide same functionality via GVariant APIs. The syntax is slightly
different mostly for how arrays, variadic types and dictionaries are
created/parsed.

Additional difference is that with GLib DBus everything is wrapped in
extra tuple (struct). For more details refer to the documentation [1].
