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.

Fixes #34690

71c31c45c7 net: dns: add dns_resolve_reconfigure() API
So far there was no dedicated mechanism for replacing DNS servers with
new list. Add dns_resolve_reconfigure() API that allows to achieve that
in a thread-safe manner.

Introduce 3rd state in DNS context lifetime by converting from 'bool
is_used' to 'enum dns_resolve_context_state state'. This new
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).

afaf52af66 net: trickle: Do not initialize a work item from its handler
Initializing a work item from its handler will destroy the content of
the kernel structures used to process the work item. This can lead to a
system crash for example when the delayed work is being rescheduled when
the previous run is already queued for processing but not yet executed.

Fix this by initializing the work item once during trickle timer
creation and moving the logic, previously achieved by switching the work
handler, into the new work handler.

f5fb80750e net: Enable running without TX or RX threads
Set the default behaviour of the networking subsystem so that
no TX or RX threads are created. This will save RAM as there
is no need to allocate stack space for the RX/TX threads.
Also this will give small improvement to network packet latency
shown here:
* with 1 traffic class (1 TX and RX thread)

Avg TX net_pkt (42707) time 60 us	[0->22->15->22=59 us]
Avg RX net_pkt (42697) time 36 us	[0->10->3->12->7=32 us]

* with 0 traffic classes (no TX and RX threads)

Avg TX net_pkt (41608) time 42 us	[0->21->20=41 us]
Avg RX net_pkt (41593) time 31 us	[0->9->12->8=29 us]

In this qemu_x86 test run, 40k UDP packets was transferred between
echo-server and echo-client. In TX the speed increase was 30% and
in RX it was 14%.

46ea8bf00c net: Append device name to linker generated symbols for struct net_if
Before this change all struct net_if objects accessed by for example
net_if_get_by_index() are placed in one linker area (i.e. net_if_area)
with the same "name" - '_net_if.static.net_if'. This may cause problems
when the order of struct net_if elements is important.

With the same names for all elements there is no guarantee of placement
order. After this change the unique device name is appended, so
SORT_BY_NAME() linker command places objects in reproductible manner.

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.

ce2abc26b5 net: capture: Catch sent and received packets
Create net_l2_send() function which will be called by each L2
sending function so that we can catch all the network packets
that are being sent. Some L2 layers send things a bit differently,
so in those cases call the net_capture_send() directly by the L2
layer.
Add network packet capture call in receive side after the pkt has
been received by the RX queue handler. This avoids calling the
net_capture_send() from ISR context.
