a5ec72418c net: openthread: Convert API worker thread to a work queue
Direct openthread API usage requires explicit locking,
which is also used internally.
Exposing a work queue through the openthread context allows
work to be submitted without the need to block other threads.

In particular with CONFIG_OPENTHREAD_MANUAL_START, application
logic can offload work which otherwise would need to wait for
the lock to become available.

05b2018ffa lwm2m: keep track of observations per client
this has a number of advantages:
- allows to only create notifications for each client if there are no
  messages already waiting to be send, in practice prioritizing the
  memory for messages for answers, thus staying more "responsive".
- saves a fair bit of memory by eliminationg now redundant client_ctx
  pointer per observer.
- fixes a potential subtle bug: previously, an observer reset would've
  stopped the first observation found with a matching token, which
  might've belonged to a differen client.

32989a38f0 lwm2m: use asynchronous socket io
This restructures the lwm2m_engine to use a non-blocking socket access
instead of the previously used blocking style, and eliminates any
socket-access from outside of the main work loop.

The main motivation behind this is an issue within nordics
nrf_modem_lib/modem-fw on nrf9160, that leads to socket send() calls to
block indefinitely when the shared memory used for
rpc-communication with the modem is already exhausted because of
incoming data.

This lead to the lwm2m_engine locking up on send calls when there is
also a large amount of incoming data.

This works around this issue, by only issuing send calls when poll
reports the socket to be ready for sending, and (more importantly) by
always receiving all buffered incoming data before sending anything.

There might still be a (perhaps academic) possibility where this
situation might be triggered, when  the scheduler interrupts the lwm2m
thread in-between receiving and sending, but for now we have not yet
observed this.

Besides working around the aforementioned issue, this also simplifies
the way resends are handled as they are no longer send from the main
system-workqueue, and limits all interaction with the sockets to a
single thread.

bcdc762609 net: Use k_fifo instead of k_work in RX and TX processing
The k_work handler cannot manipulate the used k_work. This means
that it is not easy to cleanup the net_pkt because it contains
k_work in it. Because of this, use k_fifo instead between
RX thread and network driver, and between application and TX
thread.

A echo-server/client run with IPv4 and UDP gave following
results:

Using k_work
------------
TX traffic class statistics:
TC  Priority	Sent pkts	bytes	time
[0] BK (1)	21922		5543071	103 us	[0->41->26->34=101 us]
[1] BE (0)	0		0	-
RX traffic class statistics:
TC  Priority	Recv pkts	bytes	time
[0] BK (0)	0		0	-
[1] BE (0)	21925		6039151	97 us	[0->21->16->37->20=94 us]

Using k_fifo
------------
TX traffic class statistics:
TC  Priority	Sent pkts	bytes	time
[0] BK (1)	15079		3811118	94 us	[0->36->23->32=91 us]
[1] BE (0)	0		0	-
RX traffic class statistics:
TC  Priority	Recv pkts	bytes	time
[0] BK (1)	0		0	-
[1] BE (0)	15073		4150947	79 us	[0->17->12->32->14=75 us]

So using k_fifo gives about 10% better performance with same workload.

So far there was no dedicated mechanism for replacing DNS servers with

Introduce 3rd state in DNS context lifetime by converting from 'bool

DEACTIVATING state allows to mark a DNS context as busy and safely close
context without holding lock. Closing DNS context with released lock
prevents deadlock in case net_context_close() has to synchronize with a
separate thread executing handler passed to net_context_recv() (which is
the case for example with ESP-AT WiFi driver).

958e826b69 net: socket: Workaround issue with recent GCC and fcntl macro
If we have CONFIG_NET_SOCKETS_POSIX_NAMES enabled (which is now
default), and also have CONFIG_NEWLIB_LIBC enabled, latest versions
of GCC throw a strange error like:

error: conflicting types for 'zsock_fcntl'
  692 | #define fcntl zsock_fcntl

After enough consideration, it seems that when Newlib is used, its
fcntl.h header is used, which declares fcntl() with POSIX prototype:
"int fcntl(int fd, int cmd, ...)". It seems that recent GCC, when
seeing the #define like above, checks that its right-hand side
(zsock_fcntl(int, int, int) above) is compatible with an existing
LHS prototype. That doesn't make sense from the point of view of
the C preprocessor semantics, and yet that's what apparently happens.

Make GCC happy by defining an inline wrapper function with
signature compatible with POSIX fcntl prototype, and use it in
the define, instead of zsock_fcntl directly.
