a9b926414c net: lwm2m: Publicize firmware block context
This change is to allow access to the firmware block context in order to
give the firmware update callback implementation an indication of when
to reset the flash context. Additionally, it allows for a validity check
between the total expected size downloaded and the actual size
downloaded. A simple implementation can check if the block context's
current downloaded blocks is equal to the expected block size in order
to determine if the flash context needs to be reset. This approach
seemed the simplest, and knowing the firmware block context can have
other purposes. This has been tested by accessing the block context
during the update in the block received callback and confirming that the
callback had information regarding the current downloaded bytes.

Fixes #16122

This patch updates the net_buf API to use k_timeout_t in essentially

intermediate decrements of remaining timeout is needed. For this the

1fb418df4c net: ieee802154_radio: Allow to specify TX mode
Even though radio driver can report in its capabilities that it does
support CSMA CA, there's no way in the driver to select how the frame
should be transmitted (with CSMA or without). As layers above radio
driver (Thread, Zigbee) can expect that both TX modes are available, we
need to extend the API to allow either of these modes.

This commits extends the API `tx` function with an extra parameter,
`ieee802154_tx_mode`, which informs the driver how the packet should be
transmitted. Currently, the following modes are specified:
* direct (regular tx, no cca, just how it worked so far),
* CCA before transmission,
* CSMA CA before transmission,
* delayed TX,
* delayed TX with CCA

Assume that radios that reported CSMA CA capability transmit in CSMA CA
mode by default, all others will support direct mode.

Such state needs to be set _from_ the PM API functions and not the other

actually set to suspend mode or not and also to take care of all timers

9f9e00a62d net: mqtt: Added event for MQTT ping response.
There are scenarios where there is a NAT firewall in between MQTT
client and server. In such case, the NAT TCP timeout may be shorter
than MQTT keepalive timeout and TCP timeout. The the MQTT ping
request message is dropped by the NAT firewall, so that it cannot be
received by the server, resulting in void MQTT ping response message.
There is no TCP FIN or RST at all. The application looks hang-up
until TCP timeout happens on the client side, which may take too
long.

Therefore, the event MQTT_EVT_PINGRESP is added to inform the
application that the route between client and server is still valid.

d88f25bd76 net: tcp: Handle special case where accepted socket is closed
Handle this corner case with TCP connection closing:

1) Client A connects, it is accepted and can send data to us
2) Client B connects, the application needs to call accept()
   before we will receive any data from client A to the application.
   The app has not yet called accept() at this point (for
   whatever reason).
3) Client B then disconnects and we receive FIN. The connection
   cleanup is a bit tricky as the client is in half-connected state
   meaning that the connection is in established state but the
   accept_q in socket queue contains still data which needs to be
   cleared.
4) Client A then disconnects, all data is sent etc

The above was not working correctly as the system did not handle the
step 3) properly. The client B was accepted in the application even
if the connection was closing.

only in LISTENING state" and related other commits are no longer

Use the newest version of the OpenThread project, as updated in
https://github.com/zephyrproject-rtos/openthread/pull/2.

Introduce the following fixes along with the update (they're squashed to
retain bisectability of OT samples):

* Update configs and flags used
	Some OT configs were renamed, some new were introduced that Zephyr port
	needs to set.

* Add entropy platform driver
	OpenThreads `random` platform subsystem was replaced with `entropy`
	subsystem which is supposed to serve as an entropy source for the
	generic OpenThread's random generator.

* Halt OT thread when OT command is processed
	OpenThread can currently be processed from two threads - a
	genuine OpenThread thread and shell thread, which processes CLI
	commands. This could cause trouble, when context was switched
	during OT command processing (i.e. switched to process an incomming OT
	message, while still in unfinished command handler).

	In result, it was not possible to turn the commissioner role on via
	CLI, as the commissioner petition response was handled before the
	Commissioner::Start function finished its execution (if the
	petitioner is also the network leader, all messages are passed
	internally within the stack).

	Fix this by suspending the OT thread for the time of an OT command
	processing.
