/* The problem is...
*
* NMClient is associated with a GMainContext, just like its underlying GDBusConnection
* also queues signals and callbacks on that main context. During operation, NMClient
* will schedule async operations which will return asynchronously on the GMainContext.
*
* Note that depending on whether NMClient got initialized synchronously or asynchronously,
* it has an internal priv->dbus_context that is different from the outer priv->main_context.
* However, the problem is in both cases.
*
* So, as long as there are pending D-Bus calls, the GMainContext is referenced and kept alive.
* When NMClient gets destroyed, the pending calls get cancelled, but the async callback are still
* scheduled to return.
* That means, the main context stays alive until it gets iterated long enough so that all pending
* operations are completed.
*
* Note that pending operations don't keep NMClient alive, so NMClient can already be gone by
* then, but the user still should iterate the main context long enough to process the (cancelled)
* callbacks... at least, if the user cares about whether the remaining memory and file descriptors
* of the GMainContext can be reclaimed.
*
* In hindsight, maybe pending references should kept NMClient alive. But then NMClient would
* need a special "shutdown()" API that the user must invoke, because unrefing would no longer
* be enough to ensure a shutdown (imagine a situation where NMClient receives a constant flow
* of "CheckPermissions" signals, which keeps retriggering an async request). Anyway, we cannot
* add such a shutdown API now, as it would break client's expectations that they can just unref
* the NMClient to destroy it.
*
* So, we allow NMClient to unref, but the user is advised to keep iterating the main context.
* But for how long? Here comes nm_client_get_context_busy_watcher() into play. The user may
* subscribe a weak pointer to that instance and should keep iterating as long as the object
* exists.
*
* Now, back to synchronous initialization. Here we have the internal priv->dbus_context context.
* We also cannot remove that context right away, instead we need to keep it integrated in the
* caller's priv->main_context as long as we have pending calls: that is, as long as the
* context-busy-watcher is alive.

* this GObject. Subscribe a weak reference to the returned object and keep
* iterating the main context until the object got unreferenced.

/*****************************************************************************
* Backported symbols. Usually, new API is only added in new major versions
* of NetworkManager (that is, on "master" branch). Sometimes however, we might
* have to backport some API to an older stable branch. In that case, we backport
* the symbols with a different version corresponding to the minor API.
*
* To allow upgrading from such a extended minor-release, "master" contains these
* backported symbols too.
*
* For example, 1.2.0 added nm_setting_connection_autoconnect_slaves_get_type.
* This was backported for 1.0.4 as nm_setting_connection_autoconnect_slaves_get_type@libnm_1_0_4
* To allow an application that was linked against 1.0.4 to seamlessly upgrade to
* a newer major version, the same symbols is also exposed on "master". Note, that
* a user can only seamlessly upgrade to a newer major version, that is released
* *after* 1.0.4 is out. In this example, 1.2.0 was released after 1.4.0, and thus
* a 1.0.4 user can upgrade to 1.2.0 ABI.
