Add CDC Ethernet Emulation Model function driver. This usb network
function can be used for ethernet over USB. Ethernet packet are
encapsulated within EEM packets. An EEM pkt contains 2-byte header
and 4-byte sentinel (or crc).
Note that EEM packets can be split across USB packets but shall not
be split across USB transfers.

When dns_get_addr_info() returns an error it does not call the
resolve callback, and thus the semaphore will not be given.
This fix will avoid a deadlock situation for various errors.

Callers of dns_get_addr_info() depends on receiving an end-of-results
callback (where 'info' is NULL) when finished. Do this on failure in
cb_recv() instead of pointing to an empty object.
This fix will avoid a deadlock situation in getaddrinfo().
A reply code other than "no error" in the DNS response is a typical
case when the lookup failed and this occurs.
Moved "struct dns_addrinfo info" variable from cb_recv() to dns_read()
because it was now unused in cb_recv().
Adding tests for this requires network access and a DNS server,
or a mechanism for generating a DNS response with a reply code.

Adapt the MyNewt non-volatile configuration system to become a settings
system in Zephyr.
The original code was modifed in the following ways:
* Renamed from config to settings
* Use the zephyr FCB, FS API, and base64 subsystems
* lltoa like function was added to sources as it was required but not
included in Zephyr itself.
* The original code was modified to use Zephyr's slist.h as single
linked list implementation.
* Reworked code which was using strtok_r, added function
for decoding a string to a s64_t value.
* Thank to the above the settings subsys doesn't require newlibc anymore.

net_eth_get_hw_capabilities() calls .get_capabilities() which is part
of the ethernet API but not the net_if_api that netusb implements.

Also, make the API const and give it a unique name.

With this commit it is possible to add priority to sent or received
network packets. So user is able to send or receive higher priority
packets faster than lower level packets.
The traffic class support is activated by CONFIG_NET_TC_COUNT option.
The TC support uses work queues to separate the traffic. The
priority of the work queue thread specifies the ordering of the
network traffic. Each work queue thread handles traffic to one specific
work queue. Note that you should not enable traffic classes unless
you really need them by your application. Each TC thread needs
stack so this feature requires more memory.
It is possible to disable transmit traffic class support and keep the
receive traffic class support, or vice versa. If both RX and TX traffic
classes are enabled, then both will use the same number of queues
defined by CONFIG_NET_TC_COUNT option.

Instead of always allocating both IPv6 and IPv4 address information
to every network interface, allow more fine grained address
configuration. So it is possible to have IPv6 or IPv4 only network
interfaces.
This commit introduces two new config options:
CONFIG_NET_IF_MAX_IPV4_COUNT and CONFIG_NET_IF_MAX_IPV6_COUNT
which tell how many IP address information structs are allocated
statically. At runtime when network interface is setup, it is then
possible to attach this IP address info struct to a specific
network interface. This can save considerable amount of memory
as the IP address information struct can be quite large (depends
on how many IP addresses user configures in the system).
Note that the value of CONFIG_NET_IF_MAX_IPV4_COUNT and
CONFIG_NET_IF_MAX_IPV6_COUNT should reflect the estimated number of
network interfaces in the system. So if if CONFIG_NET_IF_MAX_IPV6_COUNT
is set to 1 and there are two network interfaces that need IPv6
addresses, then the system will not be able to setup IPv6 addresses to
the second network interface in this case. This scenario might be
just fine if the second network interface is IPv4 only. The net_if.c
will print a warning during startup if mismatch about the counts and
the actual number of network interface is detected.
