Adding a cursor into net_pkt. This is used to read/write data in a much
simpler way, for pre-allocated buffers in net_pkt. This avoids API users
to deal with net_buf below directly.
However, to be used - as for the new allocators - it will require deep
net stack core and API changes.

These struct net_pkt allocators will give the possibility to allocate at
once the net_pkt and the buffer associated with, taking care of the
header space and MTU relevantly.
This enables to use the variable length allocator from net_buf. However,
it is not yet the default and is set as experimental.
As it is provided in parallel to existing allocators, it has to keep a
slab per-direction and thus a pointer in net_pkt, as well as appdata,
appdatalen etc... Resulting in "bloating" net_pkt. This will be solved
when, finally, former allocators will be removed.

Now that the security data can be loaded into and used from the
security / server objects, we can add support for LwM2M bootstrap.
This is a mode where initially a connection can be made to a server
which can update several LwM2M (including security and server
data) and then trigger a "bootstrap complete". Once this happens
the client will start it's connection process over but now with
the new information.

net_app contexts save the remote address and we use this during
observe notifications and pending handling. If we move to another

As part of the migration from net_app APIs to socket APIs, let's
stop referencing the net_pkt fragments throughout the LwM2M library.
Establish a msg_data flat buffer inside lwm2m_message and use that
instead.
NOTE: As a part of this change we remove the COAP_NET_PKT setting.
The COAP library reverts to COAP_SOCK behavior.
This doesn't mean we use sockets in LwM2M (yet), it only means we
use the socket-compatible COAP library which parses flat buffers
instead of net_pkt fragments.

The original SNTP client library was designed for the net-app API, for
which it makes sense to have a callback function, which is called
asynchronously when an answer is received.
For the socket based interface, the callback is called just before
sntp_request() returns. It gets the status and the epoch_time in
parameter, however the status is already returned by sntp_request(). It
therefore make sense to replace the callback function by a pointer to
epoch_time.

There was an existing validation layer in the spinlock implementation,
but it was only enabled when both SMP and CONFIG_DEBUG were enabled,
which meant that nothing was using it. Replace it with a more
elaborate framework that ensures that every lock taken is not already
taken by the current CPU and is released on the same CPU by the same
thread.
This catches the much more common goof of locking a spinlock
recursively, which would "work" on uniprocessor setups but have the
side effect of releasing the lock prematurely at the end of the inner
lock. We've done that in two spots already.
Note that this patch causes k_spinlock_t to have non-zero size on
builds with CONFIG_ASSERT, so expect a little data and code size
increase. Worth it IMHO.

It has been observed that some network drivers, f.ex. the SAM E70 GMAC,
call net_pkt_unref from inside the interrupt that signals the successful
transmission of a packet. This conflicts with the net_pkt_unref call
made by ethernet_send after the packet has been given to the driver.
We fix this by using an atomic_t to hold the reference count as there
might be other, difficult to find cases of net_pkt_(un)ref being used
across threads and interrupts.
The name of the element has been changed from "ref" to "atomic_ref" to
cause a compile error when code still has not been converted to use the
atomic_* functions.

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.

A recent change in how the fixup mechanism works caused several
regressions. See
https://github.com/zephyrproject-rtos/zephyr/pull/12680 for more
details about the regressions.
The core of the matter is that using defines to pass on include paths
causes interopability issues when integrating with external build
systems.
To resolve this we re-write the fixup mechanism to instead generate an
aggregated fixup file that is ready to be included at build time. Then
no paths are passed through defines and we resolve the regressions
reported.

extract_dts_includes.py has been generating DT output and then
concatenating it with fixup header files to create
'generated_dts_board.h'.
In this patch we instead introduce a source file named
'generated_dts_board.h' and have it \#include the appropriate DT
output and fixup files.
This results in a simpler system because users can now read
'generated_dts_board.h' as C source code to see how fixup files and
generated DT output relate to each other. Whereas before they would
have to either read documentation or python code to gain the same
understanding.
Also, it reduces the scope and complexity of one of our most bloated
python scripts, extract_dts_includes.py.

struct timeval is per POSIX defined in sys/time.h, but that also
allowed to pull sys/select.h (and indeed, it does with native_posix),
which then starts to conflict with out select implementation (if
NET_SOCKETS_POSIX_NAMES is defined, and many samples/tests have it).
So, for now follow the existing route of duplicating all definitions
needed by our code in namespaced manner. Things like struct timeval
usage will need to be revisited later, when we'll want socket
subsystem to work with POSIX subsystem, but that's a separate deep
