ether_aton() allows addresses like "0:1:2:3:4:5" which was casusing
some problems when reading connections after switching callers of
ether_aton() to nm_utils_hwaddr_aton().
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.

The RDNSS and DNSSL failure cases wouldn't clear out the idle
handler of a previous success (if that success hadn't fired yet);
it seems pointless to signal success and then immediately fail.
Second, it would cause a dangling GSource if the device was
removed or NM quit at the right time.
The errors appeared due to calling GetAccessPoints() on removed devices:
nm_device_wifi_get_access_points: error getting access points: Method "GetAccessPoints" with signature "" on interface "org.freedesktop.NetworkManager.Device.Wireless" doesn't exist
NMClient and NMDevice used a 'lazy' approach for getting stuff from D-Bus, i.e.
requesting data from NM when they are asked for. However, for some cases, like
removing devices it is not optimal. libnm-glib will never see a device that was
removed, but not added during NMClient's lifetime.
So let's get devices list in NMClient's constructor and device properties
in NMDevice constructor to have the data from the beginning.
In cases where the actual password is non-ASCII, it may not be
possible to deliver the 802.1x password as a D-Bus string. Instead
provide an alternate field holding the password as a byte array.
In cases where both a password and password-raw are supplied,
password is preferred.
The 802.1x password for MS-CHAPv2 can be up to 256 UCS-2 characters,
so we need to validate the password as UTF-8 to make sure we don't
reject valid passwords containing non-ASCII characters
Currently slaves only wait for the master device to be present. This is
insufficient, we want to wait for the master connection to be activated.

Revert the DEVICE and suffix bits for the connection name; there's
a few problems with this. It adds the DEVICE value for connections
regardless of what type they, even in cases where it's not hugely
useful (ie basic wired). We used to do this, but stopped doing it
because it has zero relevance to a large number of users. Instead,
the UI itself should do this where appropriate. That probably means
that 'nmcli' and other tools should give more information about
the components of a connection (like a slave device's master) and
GUI tools would show that in detailed connection information but
not in the at-a-glance status or tooltips. Second, if more
more advanced users wish this information to show up in the name
they can always set the name themselves, or name the ifcfg file
something like "ifcfg-bond1-slave-of-eth0" too.
nm_utils_hwaddr_ntoa() and nm_utils_hwaddr_aton() are like
ether_ntoa()/ether_aton(), but handle IPoIB too.
nm_utils_hwaddr_atoba() is like _aton() but returns a GByteArray,
since that's what's wanted in many places.
Also remove nm_ether_ntop() and replace uses of it with
nm_utils_hwaddr_ntoa().
We have to send agent-owned secrets to agents via SaveSecrets() D-Bus call for
newly created connections, the same way we do for connection updates.
Without the change secrets aren't saved for new created VPN connections,
only after a connection update.

This simplifies the code quite a bit since we don't need
an nl_cache or nl_family anymore.
genl_ctrl_resolve() is available in libnl1.1, libnl2 and libnl3.

Moves the logic of naming connections into its own function. Allows each
connection type to provide a "hard" prefix which will always be used.
Bonding uses this to prefix all bonding connections with "Bond".
If a DEVICE= line is available, append it to the end of connection name
for easier identification of the real device behind it.
Appends the suffix "[slave-of <MASTER>]" to all connections which are
configured as a slave of a bond.
Examples:
myName -> myName (eth0)
System eth0 -> System eth0
myName2 -> Bond myName2 (bond0)
System bond0 -> Bond bond0
myName -> myName (eth0) [slave-of bond0]
System eth0 -> System eth0 [slave-of bond0]

If the device's permanent MAC address is 'locally administered'
(ie, first byte | 0x02 != 0) then we don't want to lock the
connection to the device because it's likely a device that changes
it's MAC every hotplug due to driver bugs or the fact that some
devices don't store their MAC in EEPROM anyway.
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.
Adds a new function nm_system_apply_bonding_config() which applies
the parameters specified in the NMSettingBond object via sysfs.
Calls that function after creating/updating the bonding master
device.
If a parameter is not specified in the ifcfg the parameter will be
re-initialized to the default value. This may overwrite changes
which have been done manually via sysfs but it is the only reliable
way of setting up the bond.
Supported parameters for now:
- mode (default: balance-rr)
- miimon (default: 100)
- updelay (default: 0)
- downdelay (default: 0)
- arp_interval (default: 0)
- arp_ip_target (default: none)

Kills the strdup() and avoids having the caller free the memory. Also renames
the function to nm_system_get_iface_type() since "link" is not a common term
in NM.

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.

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.

- Made check_master_dependency() return TRUE/FALSE

Adds a MASTER= directive to ifcfg-rh allowing a connection to define
itself as bonding slave.
Adds a connection property "master" which contains the in-kernel device
name or UUID of the master connection.
Adds a connection property "slave-type" which defines the type of slave
this connection represents. Currently this is only set by bonding but
eventually this will be used by VLAN and bridging.
Enforces that no bonding slave connection has any IPv4 or IPv6
configuration set.
Changes make_ip4_setting() to take a universal flag indicating whether
to allow disabling ip4 config or not and use it for both, ip6 and
bonding special case.
