Also react on SIGUSR1 and SIGUSR2, beside SIGHUP.
Only for SIGHUP actually reload the configuration from
disc. For the other signals only emit a config-changed
signal.
Since commit ab6548c621 ("device: better accept external IP
changes"), ipX_config_merge_and_apply() applies the configuration
static settings to an intermediate, initially empty configuration
(priv->con_ipX_config) instead of the composite configuration, and
thus the handling of ignore-auto-routes and ignore-auto-dns options
done in nm_ipX_config_merge_setting() has no effect.
Fix this by clearing the routes and the DNS information when needed
before merging static settings to the composite configuration.
Fixes: ab6548c621
Example:
$ nmcli con add type eth con-name profile ifname nosuch
$ nmcli con up profile
or
# ip link set eth0 down
$ nmcli con add type eth con-name my-eth0 ifname eth0
$ nmcli con up my-eth0

Without that we can remove addresses from con-ip6-config due to external
changes *before* it is applied and thus manual IPv6 addresses are not applied
together with ipv6.method=auto.
Testcase:
$ nmcli con add type ether con-name AAA ifname eth0 autoconnect no
$ nmcli con mod AAA ipv4.addresses 1.1.1.1/24 ipv6.addresses 99::99/64
$ nmcli con up AAA

Some master connetions are able to progress beyond activating/ip-config -- the
slaves might have appeared during the activation, or the connection doesn't
need slaves to obtain the configuration (it could be method=manual or shared).
Change nm_platform_link_get() to return the cached NMPlatformLink
instance. Now what all our implementations (fake and linux) have such a
cache internal object, let's just expose it directly.
Note that the lifetime of the exposed link object is possibly quite
short. A caller must copy the returned value if he intends to preserve
it for later.
Also add nm_platform_link_get_by_ifname() and modify nm_platform_link_get_by_address()
to return the instance.
Certain functions, such as nm_platform_link_get_name(),
nm_platform_link_get_ifindex(), etc. are solely implemented based
on looking at the returned NMPlatformLink object. No longer implement
them as virtual functions but instead implement them in the base class
(nm-platform.c).
This removes code and eliminates the redundancy of the exposed
NMPlatformLink instance and the nm_platform_link_get_*() accessors.
Thereby also fix a bug in NMFakePlatform that tracked the link address
in a separate "address" field, instead of using "link.addr". That was
a case where the redundancy actually led to a bug in fake platform.
Also remove some stub implementations in NMFakePlatform that just
bail out. Instead allow for a missing virtual functions and perform
the "default" action in the accessor.
An example for that is nm_platform_link_get_permanent_address().
We must check if a conflicting route/address is configured on
*any* interface, not only on the target ifindex.
This at least restores the previous behavior. Note that this whole
check_reinstall_device_route() still has problems and it might
be better to move it all to NMRouteManager.

After doing all the refactoring, rename the ObjectType enum to NMPObjectType.
I didn't do this earlier to avoid problems with rebasing. But since I will
backport the platform changes to nm-1-0, this is the right time to get
the name right.

AUTOCONNECT_SLAVES is an NetworkManager extension. initscripts always activate
slaves with the master connection for bond and team, and doesn't activate
automatically slaves for bridge.
NetworkManager behaviour is controlled by this variable. If the variable is
missing the default value from configuration file is used.
The property is used for controlling whether slaves should be brought up with
a master connection. If 0, activating the master will not activate slaves.
But if set to 1, activating the master will bring up slaves as well.
The property can have the third state (-1), meaning that the value is default.
That is either a value set in the configuration file for the property, or 0.
