Provide an extra struct net_if * iface parameter to
net_if_ipv*_maddr_join/leave functions, so that the corresponding
interface context, the mcast address belong to, can be locked for the

There is a risk of deadlock in case net_if APIs are used from within
net_mgmt handlers as both module APIs are protected with their own
mutexes.
The scenario observed with OpenThread happend when
NET_EVENT_IPV6_ADDR_ADD/NET_EVENT_IPV6_MADDR_ADD events were processed.
The net_mgmt mutex is locked when both, an event handler is being
processed (from a separate net_mgmt thread) and when an event is raised
(for example when a new address is added on an interface). In case a
net_mgmt handler tried to use some mutex-protected net_if API, we could
end up in a deadlock situation - the net_mgmt would wait for the net_if
mutex to release, while some other thread (in this case main during
initialization) could wait within some net_if function, pending on
net_mgmt mutex to be released to notify the event.
Fix this, by preventing net_if APIs from being used from within OT
net_mgmt handlers.
Additionally, simplify the net_mgmt handlers logic, by making use of
additional info provided with an event. Instead of blindy assuming that
recently added address was the last on the list (which might not always
be the case, if addresses are added/removed dynamically), read the
actual address being added from the net_mgmt_event_callback structure.

In order to bring consistency in-tree, migrate all subsystems code to

Modifies openthread shim layer to automatically join multicast
addresses as they are added to zephyr from openthread, unless the
address is interface-local or link-local. This allows incoming
openthread multicast group messages to avoid being filtered by
zephyr ipv6 recv.

OpenThread API is not thread safe, therefore it shall be protected
from being preempted by OT thread, or other thread issuing API calls.
The problem showed up after a recent OpenThread upmerge, where changes
in the Joiner class made this problem visible. W/o extra protection,
`otJoinerStart` call can be preempted by the OT thread, leading to an
unexpected behavior.
Introduce new function to allow to lock any API operations for others.
Anyone willing to call OT APIs, shall lock the mutex first to get
exclusive access to the stack.

OpenThread BR can assign addresses via DHCPv6 or when acting as an
NCP, addresses can be added manually. Currently, those addresses are
handled in the same way as auto-configured addresses.
This patch maps the newly introduced mAddressOrigin of otNetifAddress to
Zephyr's net_addr_type.
This way an application can register a handler and differentiate by type
of assignment:
```
static void handler(struct net_mgmt_event_callback *cb,
u32_t mgmt_event,
struct net_if *iface)
{
if (iface->config.ip.ipv6->unicast[i].addr_type == NET_ADDR_DHCP) {
}
}
```

Remove LOG_MODULE_REGISTER() from net_core.h and place the

compiler errors in some cases and to make the code look similar
as other subsystems.

Instead of one global log level option and one on/off boolean
config option / module, this commit creates one log level option
for each module. This simplifies the logging as it is now possible
to enable different level of debugging output for each network
module individually.
The commit also converts the code to use the new logger
instead of the old sys_log.
