Adds a new "master" property to NMActiveConnection containing the path
of the master NMDevice if the connection has a master.

The NM 'iface' isn't always the IP iface (like for modems) so
to avoid a warning, only flush routes and addresses on deactivate
when the iface can actually handle it.
There are now three places we need delayed state transitions:
1) unavailable to disconnected
2) failed to disconnected
3) bond unavailable to disconnected
(3) wasn't doing a delayed transition, but we can't change
state from inside a state-change handler otherwise we may not
end up fully processing the current state chagne. So it needs a
delayed transition too; add some generic code to make that
easier to do.
The callers of fw_add_to_zone() were passing an 'int' (AF_INET or
AF_INET6) while that function was expecting a boolean. Thus when
IPv6 functions passed AF_INET6 that would be interpreted as TRUE
and IPv4 operations would be scheduled.
Shortcut to access the connection linked to the activation
request of a device.
The patch only replaces usage with nm_device_get_connection()
if the existing code assumes that an activation request must
be available.

Add an accessor for device rfkill type and use that instead of
GObject properties, and also use that accessor when claiming a
new device instead of checking NM_IS_DEVICE_xxxx(). Allows us
to move one step closer to making WiMAX a plugin.
NetworkManager[815]: merge_ip6_configs: assertion `src != NULL' failed
Calling ip6_config_merge_and_apply() with a NULL src_config is fine
since that's what happens during RA or DHCP lease changes.
Reported by Johannes Sjölund
If the interface has no IP configuration (bond slave, etc) then
it still needs to get activated too. Previously the code would
only move to ACTIVATED when the first IP method completed, but
since slaves don't do IP config, they never got to ACTIVATED
state.
If the IP config is missing, we just don't do any IP config, instead
of treating it as DHCP as happens for all other interface types.

Code is written generic enough to allow easy addition of further master/slave
relationships such as bridging relations.

(whitespace cleanups and libnl compat by dcbw)
For a slave to be activatetable the master connection must be present.
Activation of the slave is postponed until this condition is met.
Once the slave is being activated, a reference to the master connection
is acquired and held for the lifetime of the bond.
Changes v2:
- Made check_master_dependency() return TRUE/FALSE

src/firewall-manager tracks whether firewall is on the bus or not.
In nm-device.c at stage5 (ip-config-commit) before we actually
apply the IP configuration to the interface, we send the
IP interface name and zone to firewall and asynchronously wait
for a D-Bus reply. Then after we get the reply
(or if the firewall isn't running) we proceed with
applying the IP configuration to the interface.
Since both RA and DHCP may be run at the same time, we want to
make sure to merge both configs into a final config when either
RA or DHCP changes. Previously this only happened when RA changed,
but not when DHCP changed or completed. This caused the config
applied when DHCP completed to not contain the RA-derived address,
which was then removed from the device, which then regressed the
IPv6 RA state, causing a device failure.

Initial IP configuration can happen during ACTIVATED state if both
v4 and v6 are enabled, but one takes longer than the other. Thus
various checks throughout the code for IP_CONFIG were incorrect
since they depended on IP configuration only happening during the
IP_CONFIG state. Fix that by using a separate state for IP config
and using that state for various checks instead of the overall
device state.
It was somewhat pointless since the IP config is always known when
stage4 gets scheduled, so why not just pass the config to stage5
immediately? Also helps consolidate the v4/v6 failure handling
logic and makes the operational flow clearer where both v4 and
v6 are active and proceeding in parallel.
We don't really need to wait before both IPv4 and IPv6 are established before
applying all the settings to the device. Instead, we can apply each separately
when they are ready, which will bring up the interface sooner.
