Jukka Rissanen 61249021c0 net: socket: poll() with POLLOUT can return immediately
If we can write to the socket in POLLOUT, then there is no need to
wait.

Note that this is not a full POLLOUT implementation but prevents
the code from waiting even if we could send data out.

Fixes #18867

Martí Bolívar caa06c9c48 net: lwm2m: add optional timestamp resources to some IPSO objects
Based on work by Michael Scott.

Add a new Kconfig knob, CONFIG_LWM2M_IPSO_TIMESTAMP_EXTENSIONS. This
defaults to n. When enabled, various IPSO objects will by default have
the timestamp resource (5518) added to their representations. This can
be turned off on a per-object basis.

The idea of adding timestamp resources was originally suggested by
Hannes Tschofenig on this OMA page:

manual cleanup (big letter at the start, etc.)

Ulf Magnusson 975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Jukka Rissanen 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.

After this commit, the commit called "net: tcp: Accept connections
only in LISTENING state" and related other commits are no longer
needed and are reverted.

Robert Lubos 83bb911a21 net: openthread: Update OpenThread version
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.

Doing this in a dedicated init function is the cleanest and most
