In the IEEE 802.15.4 area certain settings must be set before
net_if_up() may be called (e.g. the channel).
Also net_if_up() may not be called if

This fixes the set-up order and handling of

Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.
The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);
has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);
The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.
All in-tree uses of the function have been adapted.

Add TLS_DTLS_CID socket option, which enables to use the Connection ID
extension for the DTLS session.
The option provides control of the use of CID with the `setsockopt()`
function. The value provided can disable, enable, and control whether to
provide a CID to the peer. It uses a random self CID (if told to provide
one to the peer) unless TLS_DTLS_CID_VALUE set previously.
Add TLS_DTLS_CID_VALUE to get or set the CID sent to the peer, if any.
Add TLS_DTLS_PEER_CID_VALUE to get the CID value provided by the peer,
if any.
Add TLS_DTLS_CID_STATUS to determine if CID used, and whether
bidirectional or one way.

getsockname() did not work properly on bound sockets, as it verified
whether the socket has an active connection before retuning result. This
is not correct, as socket after bound may not have a connection yet.
Fix this, by verifying that local_addr on an underlying net_context is
set, to determine whether socket has a local address assigned, before
returning result.

The previous patch to address race condition on STREAM sockets had a
side effect on DGRAM socket, where net_context_recv() is not only
installing recv callback, but also registering a connection at net_conn
level. Doing so before setting remote address first (which is done in
net_context_connect()) had an impact on the connected DGRAM socket
operation, which now accepted packets from any remote peer, and not only
the one socket was connected to.

The `ioctl()` interface is already supported by the network
subsystem but there was no `zsock_` interface available for it.
Add the `zsock_ioctl()` syscall.
Implement two somewhat commont ioctl requests for socket
file descriptors; namely
- `FIONBIO` set non-blocking I/O mode
- `FIONREAD` get the number of available bytes
In the process, added `net_pkt_ip_proto_hdr_len()`
Signed-off-by: Christopher Friedt <cfriedt@meta.com>
In order to get a semi-accurate assessment of how many
bytes are available on a socket prior to performing a read,
BSD and POSIX systems have typically used
`ioctl(fd, FIONREAD, &avail)`
We can support this in Zephyr as well with little effort, so
add support for `socketpair()` sockets as an example.

Previously, if a net_context had multiple packets already in
the receive queue, and a call to zsock_recvfrom() was made with
a buffer large enough to receive content from multiple packets,
only the content from a single receive buffer would be received.
Since zsock_recvfrom() is a system call, which has a
non-negligible overhead, it makes sense to receive as many bytes
as possible per system call.
Add zsock_recv_stream_immediate() as a shorthand for
"fill this receive buffer with as many bytes as possible without
blocking". Allow nullable buffer parameters so that we can also
have a shorthand for "count how many bytes are immediately
available".
With minor refactoring, zsock_recv_stream_timed() is a simple
wrapper around zsock_recv_stream_immediate() that handles timing
and error conditions.

The initial goal was to remove sys_clock_timeout_end_calc(). However,
several related issues have been fixed as well.
First this:
int64_t print_interval = sys_clock_timeout_end_calc(K_SECONDS(1));
/* Print log every seconds */
int64_t print_info = print_interval - k_uptime_ticks();
if (print_info <= 0) {
[...]
}
The above condition will simply never be true.
Then there is lots of back-and-forth time conversions using expensive
base-10 divisions for each loop iterations which is likely to impact
performance.
Let's do the time conversion only once outside the loop and track
everything in terms of ticks within the loop. Also the various timeouts
are open-coded based on the absolute uptime tick so to sample it only
once per round. Using sys_timepoint_calc() and sys_timepoint_timeout()
would have introduced additional uptime tick sampling which implies the
overhead of a downstream lock each time for no gain. For those reasons,
open coding those timeouts bears more benefits in this particular case
compared to using the timepoint API.
Then this:
secs = k_ticks_to_ms_ceil32(loop_time) / 1000U;
usecs = k_ticks_to_us_ceil32(loop_time) - secs * USEC_PER_SEC;
The above should round down not up to work accurately. And the usecs
value will become garbage past 1.2 hour of runtime due to overflows.
And no need to clamp the wait period which is on the microsec scale
using the total duration argument being on the millisec scale. That's
yet more loop overhead that can be omitted. The actual duration is
recorded at the end anyway.
