We need this for a little little longer :(

This reverts commit 1de8383a.

"nm-macros-interal.h" already includes <errno.h> and <string.h>.
No need to include it everywhere else too.

This speeds up the initial object tree load significantly. Also, it
reduces the object management complexity by shifting the duties to
GDBusObjectManager.

The lifetime of all NMObjects is now managed by the NMClient via the
object manager. The NMClient creates the NMObjects for GDBus objects,
triggers the initialization and serves as an object registry (replaces
the nm-cache).

The ObjectManager uses the o.fd.DBus.ObjectManager API to learn of the
object creation, removal and property changes. It takes care of the
property changes so that we don't have to and lets us always see a
consistent object state.  Thus at the time we learn of a new object we
already know its properties.

The NMObject unfortunately can't be made synchronously initializable as
the NMRemoteConnection's settings are not managed with standard
o.fd.DBus Properties and ObjectManager APIs and thus are not known to
the ObjectManager.  Thus most of the asynchronous object property
changing code in nm-object.c is preserved. The objects notify the
properties that reference them of their initialization in from their
init_finish() methods, thus the asynchronously created objects are not
allowed to fail creation (or the dependees would wait forever). Not a
problem -- if a connection can't get its Settings, it's either invisible
or being removed (presumably we'd learn of the removal from the object
manager soon).

The NMObjects can't be created by the object manager itself, since we
can't determine the resulting object type in proxy_type() yet (we can't
tell from the name and can't access the interface list). Therefore the
GDBusObject is coupled with a NMObject later on.

Lastly, now that all the objects are managed by the object manager, the
NMRemoteSettings and NMManager go away when the daemon is stopped. The
complexity of dealing with calls to NMClient that would require any of
the resources that these objects manage (connection or device lists,
etc.) had to be moved to NMClient. The bright side is that his allows
for removal all of the daemon presence tracking from NMObject.

- All internal source files (except "examples", which are not internal)
  should include "config.h" first. As also all internal source
  files should include "nm-default.h", let "config.h" be included
  by "nm-default.h" and include "nm-default.h" as first in every
  source file.
  We already wanted to include "nm-default.h" before other headers
  because it might contains some fixes (like "nm-glib.h" compatibility)
  that is required first.

- After including "nm-default.h", we optinally allow for including the
  corresponding header file for the source file at hand. The idea
  is to ensure that each header file is self contained.

- Don't include "config.h" or "nm-default.h" in any header file
  (except "nm-sd-adapt.h"). Public headers anyway must not include
  these headers, and internal headers are never included after
  "nm-default.h", as of the first previous point.

- Include all internal headers with quotes instead of angle brackets.
  In practice it doesn't matter, because in our public headers we must
  include other headers with angle brackets. As we use our public
  headers also to compile our interal source files, effectively the
  result must be the same. Still do it for consistency.

- Except for <config.h> itself. Include it with angle brackets as suggested by
  https://www.gnu.org/software/autoconf/manual/autoconf.html#Configuration-Headers

config.h should be included from every .c file, and it should be
included before any other include. Fix that.

(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)

As with NMIP4Config and NMIP6Config, merge the two DHCP config classes
into one in the public API.

A parenthesized comment in nm-dbus-interface.h was being misparsed as
an annotation.

The annotations on NMDhcp4Config:options and NMDhcp6Config:options
were incorrect.

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).

Add _nm_object_class_add_interface(), for declaring that a class
implements a particular interface, and then have NMObject create the
corresponding proxies itself. (The subclass can get a copy with
_nm_object_get_proxy() if it needs it for something).

(In GDBus, creating a proxy is a heavier operation than in dbus-glib,
so we'll need to create the proxies asynchronously. Moving the
creation to NMObject makes that easier since we can do it as part
of the existing init/init_async.)

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.

"NetworkManager.h"'s name (and non-standard capitalization) suggest
that it's some sort of high-level super-important header, but it's
really just low-level D-Bus stuff. Rename it to "nm-dbus-interface.h"
and likewise "NetworkManagerVPN.h" to "nm-vpn-dbus-interface.h"

Remove _nm_object_ensure_inited(), etc; objects that implement
GInitable are now mandatory-to-init().

Remove constructor() implementations that sometimes return NULL; do
all the relevant checking in init() instead.

Make nm_client_new() and nm_remote_settings_new() take a GCancellable
and a GError**.

Rather than having each object type override constructed() to call
_nm_object_register_properties(), have NMObject call a virtual method
on the subclass to ask it to register them.

Move some code around in nm-client.c and nm-object.c so that all
D-Bus-related initialization happens in init_dbus(), and
non-D-Bus-related stuff stays in construct().

(This simplifies the next commit.)

Most NMObjects should not be manually created, they should only be
received from NMClient or NMRemoteSettings.

GLib/Gtk have mostly settled on the convention that two-letter
acronyms in type names remain all-caps (eg, "IO"), but longer acronyms
become initial-caps-only (eg, "Tcp").

NM was inconsistent, with most long acronyms using initial caps only
(Adsl, Cdma, Dcb, Gsm, Olpc, Vlan), but others using all caps (DHCP,
PPP, PPPOE, VPN). Fix libnm and src/ to use initial-caps only for all
three-or-more-letter-long acronyms (and update nmcli and nmtui for the
libnm changes).

This commit begins creating the new "libnm", which will replace
libnm-util and libnm-glib.

The main reason for the libnm-util/libnm-glib split is that the daemon
needs to link to libnm-util (to get NMSettings, NMConnection, etc),
but can't link to libnm-glib (because it uses many of the same type
names as the NetworkManager daemon. eg, NMDevice). So the daemon links
to only libnm-util, but basically all clients link to both.

With libnm, there will be only a single client-visible library, and
NetworkManager will internally link against a private "libnm-core"
containing the parts that used to be in libnm-util.

(The "libnm-core" parts still need to be in their own directory so
that the daemon can see those header files without also seeing the
ones in libnm/ that conflict with its own headers.)

[This commit just copies the source code from libnm-util/ to
libnm-core/, and libnm-glib/ to libnm/:

  mkdir -p libnm-core/tests/
  mkdir -p libnm/tests/
  cp libnm-util/*.[ch] libnm-util/nm-version.h.in libnm-core/
  rm -f libnm-core/nm-version.h libnm-core/nm-setting-template.[ch] libnm-core/nm-utils-enum-types.[ch]
  cp libnm-util/tests/*.[ch] libnm-core/tests/
  cp libnm-glib/*.[ch] libnm/
  rm -f libnm/libnm_glib.[ch] libnm/libnm-glib-test.c libnm/nm-glib-enum-types.[ch]
  cp libnm-glib/tests/*.[ch] libnm/tests/

]

Fix indentation, kill trailing whitespace, split some long lines.

- Remove list of authors from files that had them; these serve no
  purpose except to quickly get out of date (and were only used in
  libnm-util and not libnm-glib anyway).

- Just say "Copyright", not "(C) Copyright" or "Copyright (C)"

- Put copyright statement after the license, not before

- Remove "NetworkManager - Network link manager" from the few files
  that contained it, and "libnm_glib -- Access network status &
  information from glib applications" from the many files that
  contained it.

- Remove vim modeline from nm-device-olpc-mesh.[ch], add emacs modeline
  to files that were missing it.

Remove all remaining GParamSpec name and blurb strings (and fix
indentation while we're there), and add G_PARAM_STATIC_STRINGS to all
paramspecs that were lacking it.

When using a private connection, we need to use dbus_g_proxy_new_for_peer()
because the bus isn't involved.  Since many parts of libnm-glib create a
proxy for their corresponding remote object, consolidate the proxy creation
logic.

A later patch will add logic to use a private connection versus a bus-based
one.

The GOI syntax changed a while back and these didn't follow.

This reverts commit 0e0b5da7.

Syntax actually uses () instead of <> for various docbook-related
reasons.

We need to do _nm_object_ensure_inited() /
_nm_remote_settings_ensure_inited() from the get_property()
implementations; in most cases, get_property() just calls another
accessor method (which will call _nm_object_ensure_inited()), but in a
few places, it reads priv->whatever directly, so we need to make sure
that it's valid.

Implement GInitable and GAsyncInitable in NMObject, with
implementations that synchronously or asynchonously load all
properties, and change _nm_object_ensure_inited() to run
g_initable_init().

Update the object/object-array property handling to initialize the
objects after creating them (synchronously or asynchronously,
according to the situation), so that they will have all of their
properties preloaded before they are ever visible to the caller.

Move the non-blocking/non-failable parts of various objects'
constructor() methods to constructed(), and move the blocking/failable
parts to init(), and implement init_async() methods with non-blocking
versions of the blocking methods.

Make nm_device_new() and nm_client_new() call
_nm_object_ensure_inited(), to preserve the behaviour formerly
enforced by their construct() methods, that properties are guaranteed
to be initialized before any signals involving them are emitted.

Rather than having every property getter method have code to fetch
that specific property's value, just call the new
_nm_object_ensure_inited() (which makes sure that we've read all the
property values on the object at least once), and then return the
cached value. (After we've read the initial property values, the
PropertiesChanged signal handler will ensure that the values are kept
up to date, so we can always just return cached property values after
that point.)

This then lets us get rid of _nm_object_get_property() and its
wrappers.

Rename _nm_object_handle_properties_changed(), etc, to be about
properties in general, rather than just property changes.

Interpret func==NULL in NMPropertiesInfo as meaning "use
_nm_object_demarshal_generic", and then reorder the fields so that you
can just leave that field out in the declarations when it's NULL.

Add a way to register properties that exist in D-Bus but aren't
tracked by the NMObjects, and use that for NMDevice's D-Bus Ip4Address
property, replacing the existing hack.

Also add a few other missing properties noticed along the way.

Fix some annotations and add the necessary ones for new functions.

It allows us to get the error back and have control over printing
the error.

Add the necessary annotations (the mininum required, that is those
on return values. NULL parameters or container types may require
more), and the Autotools stuff to get a NetworkManager GIR for
libnm-util and a NMClient for libnm-glib.

Busted since 2008 apparently.  Oops.
