Given that Bootstrap Discovery procedure differs a lot from the regular

It is documented that using transient information like whether a work
item is pending or a delayed work item has time left to determine the
state of the work item before subsequent reconfiguration is prone to
race conditions, and known to produce unexpected behavior in the
presence of preemptive threads, SMP, or use of the work item from
interrupts. As a best practice such pre-validation steps should be
avoided unless algorithmically necessary.
All comparisons of remaining delayed time before canceling a delayed
work item in this module appear to be optimizations subject to the
above race conditions. Remove the checks so that only the inherent
race conditions in the implementation of canceling a work item remain.

LwM2M engine by default sends piggybacked responses for requests after

Current implementation had several oversimplifications, making it not

* DELETE `/x` was handled as DELETE `/x/0`, therefore not removing all

Since the above is only supported during bootstrap and not regular
Device management, this functionality was implemented in the
`bootstrap_delete` function, which now will be called for all DELETE
operations initiated during bootstrap. The regular LwM2M DELETE handler
will only be called during regular Device management, as it has more
strict limitations on what can be deleted.
Additionally, handle empty URI Path option as `/`, therefore indicating

Currently, when socket errors occur during receive, the LwM2M engine
restarts the state machine and registers again to the server. While this
works in simple use case (only RD client socket open), it's not a valid
approach when more sockets are open (FW update socket).
Fix this by introducing socket fault callback, which is registered by
the LwM2M engine users. This way, a proper socket owner is notified on
error and can pertake appropriate action.
For RD socket errors the behaviour remains the same - the state machine
is reset and the client registers again to the server. For FW update
socket, handle the error by reopening the socket and retransmitting the
last request. This allows to resume the download from the point the
error occured, w/o a need to start from scratch.

According to LwM2M specfication v1.0.2, par. 5.3.2, the LwM2M client
MUST send an “Update” operation to the LwM2M Server whenever the
lifetime parameter of the Server object changes the server). The same
applies for the object instances created/deleted. The changes in objects
seem to already be handled, but the lifetime was not.
Additionally, the "Update" message shall only contain these parameters
which changed since the last update (including objects). As it's
straightforward to determine if the liftime changed but it's not easy
to tell if there were updates in the object instances, add an
additional parameter to the engine_trigger_update() function, indicating
that new object information shall be sent in the "Update" message.

Separate response handling implemented in the engine was faulty. The
separate response was not acknowledged by the client, resulting in
spurious retransmissions from the server side.
Also, the pending CON message was retransmitted by the client even after
it was acknowledged by an empty ACK, but the respnse haven't arrived
yet. Fix this by adding a new `acknowledged` flag to the `lwm2m_message`
structure. Once acknowledged, the flag is set and the confirmable
message is no longer retransmitted. We keep the message on the pending
list in order to timeout properly in case separate response does not
arrive in time.
Finally, prevent the reply callback from being called twice in case
the response is transmitted separately from ACk. The callback should
only be called on the actual reply, not the empty ACK.

Prior to this commit, the LwM2M stack would TLV-encode integers

This commit checks if the value is castable to a smaller int and encodes
it as such if so. This is cascading, so even a 64 bit integer with value
5 will be encoded with length 1.

MQTT client state is protected using mutex. That mutex however is
temporarily unlocked when calling event callbacks. This means that in
client_disconnect() transport can already be disconnected, but without
marking it as such in client->internal.state.
When mutex is unlocked in event_notify() function, then there are two
possible paths of failure:
1) First possibility is when RX and TX are called from two separate
threads, so that the other thread gets resumed and functions like
verify_tx_state() (e.g. in mqtt_publish()) allow to continue
communication over disconnected medium.
2) Another possibility is that user calls mqtt_abort() or
mqtt_disconnect() in event handler.
In both cases MQTT library tries to send or receive data, possibly
followed by second close() of underlying file descriptor.

after calling mqtt_transport_disconnect(), without releasing mutex, even

Given that the offloaded poll handling differs from the poll handling of
native sockets (entire poll function call is offloaded), some
adjustements were needed to make TLS socket work with offloaded poll
calls.
To achieve this, in case socket offloading is used, instead of jumping
directly to the offloaded poll call, a TLS wrapper for the offloaded
poll will be called. This wrapper will do additional checks at the
mbedtls level, to verify that the event is only notified to the caller
when the application data is available (i. e. not to report events
during handshake or when partial data is received, not ready to
decrypt).

Separate TLS sockets implementation from net_context layer. Instead of
calling net_context functions directly, create an underlying TCP/UDP
socket, and call socket functions on it instead. This results in a
simpler design, where we don't need to duplicate specific parts of code
from the native socket implementation. Additionally, this allows to use
a different TCP/UDP stack underneath (i. e. when sockets offloading is
used).

This commit adds helper function to verify protocol, which was done in
two different places in the code. The function returns the underlying
protocol information on success.

Entropy device, as being unique here, does not need to be passed through
mbedtls and can instead set static locally.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver

Following are the changes to variable names that are matching
with tag names (Rule 5.7 violations)
In kernel.h, event_type is matching with a tag name in
lib/os/onoff.c. Added a _ prefix to event_type and
also to the macro argument names.
In userspace.c, *dyn_obj is matching with the tag name
dyn_obj in the file itslef. Changed it to dyn
In device.h, device_mmio.h, init.h and init.c,
changed the *device to dev. Except for one change in
init.h

Add more tests to verify that we discard malformed packets.
In order to simplify the testing, separate message validation to
dns_validate_msg() function in resolve.c. Allow that function to
be called from unit test. This way we can construct invalid DNS
messages in unit test and verify that they are discarded when
needed.
