nm-dbus-helpers-private.h is a private header file to libnm-glib/.

nm-settings-connection-glue.h and nm-settings-glue.h are not part
of libnm-glib/, they are inside src/.

Rename libnm's NMVpnPlugin to NMVpnPluginOld, in preparation for
having a new-and-improved NMVpnPlugin in NM 1.2. Also remove it from
NM-1.0.gir.

Make nm-vpn-plugin-old.h be separately includable, since it's not
included from NetworkManager.h, and we probably don't want it to be.

Remove NMVpnPlugin, NMVpnPluginUiInterface, and nm-vpn-plugin-utils
from the docs, since they're basically undocumented anyway.

Make NMRemoteSettings internal and have NMClient wrap all of its APIs,
just like it does with NMManager.

Port libnm-core/libnm to GDBus.

The NetworkManager daemon continues to use dbus-glib; the
previously-added connection hash/variant conversion methods are now
moved to NetworkManagerUtils (along with a few other utilities that
are now only needed by the daemon code).

In preparation for porting to GDBus, make nm_connection_to_dbus(),
etc, represent connections as GVariants of type 'a{sa{sv}}' rather
than as GHashTables-of-GHashTables-of-GValues.

This means we're constantly converting back and forth internally, but
this is just a stepping stone on the way to the full GDBus port, and
all of that code will go away again later.

There's not much point in keeping them separate: all existing
libnm-glib-vpn users also link against libnm-glib, and the amount of
extra code added to libnm by merging in libnm-vpn is negligible.

Additionally, nm-vpn-plugin will later need access to some
libnm-internal APIs.

So, merge them together.

The docs for NMIP4Config:addresses and NMIP4Config:routes claimed that
they were GPtrArrays of NMIP4Address/NMIP4Route, but get_property()
was actually trying to set them the D-Bus representation type, and it
was failing anyway because it used g_value_set_boxed() on a parameter
that was declared GParamSpecPointer. Fix it to use a GPtrArray-valued
property, and set it to the right thing.

NMIP6Config did the right thing with its :addresses and :routes
properties, but was using custom types (NM_TYPE_IP6_ADDRESS_OBJECT_ARRAY and
NM_TYPE_IP6_ROUTE_OBJECT_ARRAY). Make it use G_TYPE_PTR_ARRAY instead.

nm-types.c, nm-types.h, and nm-types-private.h are now empty, and so
can be dropped.

Add a header file to expose private utility functions from libnm-core
that can be used by NetworkManager (core) and libnm.so. The header
is also used to give privileged access to libnm-core. Since NM links
statically, these functions are not exported and not part of public ABI.

This also removes the NM_UTILS_PRIVATE_CALL() macro and libnm.so no
longer exports nm_utils_get_private().

Before, this functionality was partly declared in nm-utils-private.h.
This was wrong because nm-utils-private.h is for functionality
entirely private to libnm-core.
