Also, return a verdict instead of a pointer to net_pkt. It's simpler as
it will be up to net_send_data()'s caller to unref the net_pkt in case
of NET_DROP: less places where net_pkt can be unref.

This commit introduces a concept of mesh-local IPv6 addresses. Such
addresses should only be used for mesh-local communication, therefore
should not be used to communicate with different subnets (i. e.
destinations outside the mesh).
As `addr_type` field already holds different kind of information
(whether address was created automatically/manually) it was not used in
this case.
Instead a mesh_local flag was added, so that we do not lose information
on how address was created. Address with such flag set will only be
selected as a source address automatically if the destination address
is within the same subnet it belongs to.

Remove network specific default and max log level setting
and start to use the zephyr logging values for those.
Remove LOG_MODULE_REGISTER() from net_core.h and place the
calls into .c files. This is done in order to avoid weird
compiler errors in some cases and to make the code look similar
as other subsystems.

Such sent flag is in a union in net_pkt, shared with a gptp flag.
Tweaking it when the family is not AF_INET or AF_INET6 will generate

The problem is that net_if_call_timestamp_cb only checked if the
callback was registered for the PORT which invoked the whole action.
There is a possibility, that the callback will be registered, and packet
A will be passed to eth driver. Before the driver is finished with
packet A, network layer will start handling another packet (B) - so it
will unregister the callback for packet A and register it for B. After
that the network driver will finish processing packet A and invoke the
timestamp callback. The mechanism would then only check if a callback is
registered for the port of the driver and invoke the callback for the
packet that was registered earlier (so A instead of B).
This commit fixes that by storing info not only about the port but about
the packet too.
