This breaks API and ABI for the functions related to Reapply,
which got introduced in the current 1.1 development phase.
The version-id is here to allow users to error out if the connection
on the device was changed by a concurrent action.
https://bugzilla.gnome.org/show_bug.cgi?id=761714
This field will be later used by NMDevice's Reapply and
GetAppliedConnection methods. The usecase is to first fetch
the currently applied connection, adjust it and reapply it.
Using the version-id, a concurrent modification can be detected
and Reapply can reject the invocation.
Otherwise, a tun device from external openvpn service will be managed by
NetworkManager.

Some drivers (or things outside NM like 'powertop') may turn powersave
on, so don't touch it unless explicitly configured by user.
To achieve this, add new 'default' and 'ignore' options; the former
can be used to fall back to a globally configured setting, while the
latter tells NM not to touch the current setting.
When 'default' is specified, a missing global default configuration is
equivalent to 'ignore'.
It is possible to enable Wi-Fi power saving for all connections by
dropping a file in /etc/NetworkManager/conf.d with the following
content:
[connection]
wifi.powersave=3

RFC 3442 allows a default gateway to be specified in option 121
(Classless Static Routes) and override the Router option. Implement
this in the internal DHCP client.

Get rid of NM_UNMANAGED_DEFAULT and refine the interaction between
unmanaged flags, device state and managed property.
Previously, the NM_UNMANAGED_DEFAULT was special in that a device was
still considered managed if it had solely the NM_UNMANAGED_DEFAULT flag
set and its state was managed. Thus, whether the device (state) was managed,
depended on the device state too.
Now, a device is considered managed (or unmanaged) based on the unmanaged
flags and realization state alone. At the same time, the device state
directly corresponds to the managed property of the device. Of course,
while changing the unmanaged flags, that invariant is shortly violated
until the state transistion is complete.
Introduce more unmanaged flags whereas some of them are non-authorative.
For example, the EXTERNAL_DOWN flag has only effect as long as the user
didn't explicitly manage the device (NM_UNMANAGED_USER_EXPLICIT). In other
words, certain flags can render other flags ineffective. Whether the device
is considered managed depends on the flags but also at the explicitly unset flags.
In a way, this is similar to previous where NM_UNMANAGED_DEFAULT was ignored
(if no other flags were present).
Also, previously a device that was NM_UNMANAGED_DEFAULT and in disconnected
state would transition back to unmanaged. No longer do that. Once a device is
managed, it stays managed as long as the flags indicate it should be managed.
However, the user can also modify the unmanaged flags via the D-Bus API.
Also get rid or nm_device_finish_init(). That was previously called
by NMManager after add_device(). As we now realize devices (possibly
multiple times) this should be handled during realization.

It could be that what changed is the unrealize flag, not the number available
connections. That could happen when a last connection for a software device
is removed.
The nm_device_check_connection_available() call seem to have been accidentally
removed from nm_device_recheck_available_connections() resulting in all
connections always being added.

This should avoid a race when stopping dnsmasq.
This is still a hack, because we don't want to ever wait
for a process to terminate.
A better solution would be to have nm-dnsmasq-manager managing
the global state. Not only the dnsmasq instance of on NMDevice.
Instead it should keep track of all the child processes it starts
and it wants to start. This way, starting a new process should be
delayed until any (child or non-child) instances are gone.
That however would be a bigger change.

Often a netlink event doesn't contain enough information to determine
the link type. Then we consult sysctl or ethtool. However, if we already
have the same object cached, we want to reused the (once detected) link-type.
There was a bug in lookup of the cached object.
- "gsystem-local-alloc.h" and <gio/gio.h> are already included via
"nm-default.h". No need to include them separately.
- include "nm-macros-internal.h" via "nm-default.h" and drop all
explict includes.
- in the modified files, ensure that we always include "config.h"
and "nm-default.h" first. As second, include the header file
for the current source file (if applicable). Then follow external
includes and finally internal nm includes.
- include nm headers inside source code files with quotes
- internal header files don't need to include default headers.
They can savely assume that "nm-default.h" is already included
and with it glib, nm-glib.h, nm-macros-internal.h, etc.
Due to a kernel bug [1], we sometimes receive spurious NEWLINK
messages after a wifi interface has disappeared. Since the link is not
present anymore we can't determine its type and thus it will show up
as a Ethernet one, with no address specified. Request the link again
to check if it really exists.

The dnsmasq process started as DHCP and DNS server for shared
connections now accepts additional configuration files at
/etc/NetworkManager/dnsmasq-shared.d/.

When NM tries to match a generated connection to a persistent one, it
considers also the metric of static routes. However, if the field is
set to -1 (use default value for the device) on the persistent
connection, the comparison will always fail because the generated
connection contains the actual value read from kernel.
To fix the issue, modify check_possible_match() to deal correctly with
-1 and translate it to the expected value for the current device when
performing the comparison.
This allows connections with static routes and default metric to
properly be re-assumed when NM is restarted.

The existing checks assumed that all AP/AdHoc connections would use the
shared IP method. But what we really want to check for here is whether the
connection is AP/AdHoc. Leave the existing 'shared' check for backwards
compatibility.
Also move the check above the timestamp check, since the user shouldn't need
to manually set a timestamp just to get an AP-mode connection to autoconnect.
NetworkManager does not allow default routes to be specified
as normal routes. They must be ignored. Especially, iproute2
which reads the ifcfg files in initscripts, does not allow
to specify a prefix length "default/x" except for "default/0".

When exporting an object, we first set the object path and then create
GDBus interface skeletons. While doing this, a signal can be generated
[1] and then nm_exported_object_signal_hook() can trigger the failed
assertion "interface != NULL" because the object is already exported
(priv->path != NULL) but the interface has not been registered yet.
To fix this, set the object path only after skeletons have been
created.

We detect support for IPv6 temporary addresses (IFA_F_MANAGETEMPADDR) or /64 v6 prefixes
(IFA_F_NOPREFIXROUTE) based on the presence of extended address flags. For the most part
this just works, but it fails down if upon initialization no addresses are present.
In such a case we would have assumed no support. Change that to default to available
support as the feature is already 2 years in upstream kernel.
Since commit 9ff161b2a1 ("device: move have_ip6_address() to
nm_ip6_config_get_address_first_nontentative()") the IP configuration
argument of nm_ip6_config_get_address_first_nontentative() must be
non-NULL. Add checks where needed.
Fixes: 9ff161b2a1
We should not check ip6_config for the link local address because
ip6_config contains the merged settings we want to configure,
not the addresses that are actually configured on the device.
Check ext_ip6_config_captured for that.
Also, reuse nm_ip6_config_get_address_first_nontentative() which
only takes an address after it survived DAD.
