This provides the infrastructure to create network packet filter rules
and to apply them to the RX and TX packet paths. Rules are made of
simple condition tests that can be linked together, creating a facility
similarly to the Linux iptables functionality.
A couple of generic and Ethernet-specific condition tests are also
provided.
Additional tests can be easily created on top of this.

Adds support for LWM2M object 9 Software management.
This is implemented according to this release:
http://openmobilealliance.org/release/LWM2M_SWMGMT/V1_0_1-20200616-A/
Note that the XML is lacking some resources and for that reason those
resources are not included. This is a known problem by OMA and will be
fixed in a later releases.
This uses the lwm2m_pull_context to pull binaries in case
FIRMWARE_PULL_SUPPORT is enabled

Add a semaphore to control that no collisions occur when multiple

Make it possible to reuse the pull logic from firmware_pull.c by
separating it to a separate file.
The firmware_pull_context is still owned and statically allocated in
firmware_pull.c and is being passed into lwm2m_pull_context.c as a
pointer.
In other words, pull_context, does not keep any state except for a
pointer to the context currently in use.

When new route is allocated, a corresponding NBR entry (containing
`struct net_route_nexthop` data) is allocated from
`net_route_nexthop_pool`. When the route was deleted however, the entry
was not freed - only the "core" neighbor entry from the neighbor
management module (nbr.c) was dereferenced. This lead to a resource
leak, effecitevly leaking one `net_route_nexthop_pool` entry for each
deleted route.
Fix this, by defreferencing the NBR entry corresponding to the `struct
net_route_nexthop` data of the deleted route when route is removed.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
Verify the `ref` value of the neighbor entry in `net_route_foreach()`,
so that it only executes the callback on routes in use. Otherwise, the
function could call the callback for the route that has already been
deleted.
This could be encountered when executing `net route` shell command,
which printed the already deleted routes along the existing ones.

The device PM subsystem _depends_ on device, not vice-versa. Devices

Transition the `user_data` field in `struct net_buf` to be a flexible
array member instead of a hardcoded array. Compile-time asserts are
introduced at the location of the intermediate struct usage to ensure
that the assumptions utilised in runtime code hold true.
The primary assumptions are that the two `user_data` fields exist at the
same memory offset, and that the instantiated struct size can be
determined from the generic struct size and the length of the user data.
`net_buf_id` and `pool_get_uninit` must now use manual address
calculations as the `__bufs` type is no longer the actual size of the
instantiated variable.

Store the `user_data` array size on both the pool and net_buf structs.

There was a problem with source address selection for ARP
retransmissions, when an ARP entry was already pending. In such case,
the `entry` value passed to `arp_prepare()` is NULL, which in result
caused the `current_ip` variable being used as the source value. The
problem with this approach is, that the `current_ip` is only set in
IPv4 autoconf, the Ethernet L2 does not set this variable. In result,
every retransmission of an ARP packet was sent with unspecified source
address, preventing the response from being handled.
Fix this by partially restoring the behaviour of the ARP source address
assignment from before IPv4 autoconf was introduced. If the ARP is sent
by the IPv4 autoconf, use the `current_ip` value provided. If entry is
not set, use the source IPv4 address set in the actual data packet.
Otherwise, search for a source address on the interface corresponding to
the `entry`.

OpenThread has changed it's behaviour in terms of prompt printing in the
CLI module. Previously it was only printed on the UART CLI backend, now
it's printed on every CLI backend. This results in a double prompt being
printed when combined with Zephyr shell (one from OT and other form
Zephyr).
This commit adds a temporary fix to prevent OT prompt from being printed
in Zehpyr shell. As a long term solution we should add an option to
OpenThread to allow to disable prompt on the output.
