For code clarity, this commit adjusts the use of `return` statements
in functions with a void return type as follows:
- Transform `return foo();` into separate statements:
`foo();`
`return;`
- Remove unnecessary `return` statements when
they don't affect control flow.

In case peer goes down or we disconnect from the network during the
TLS handshake, the TLS socket may block indefinitely during
connect()/accept(), waiting for data from the peer. This should be
avoided, hence use the preconfigured timeout for the TLS handshake,
same as we use for TCP-level handshake.

According to recvmsg man page, msg_controllen should be set to the sum
of the length of all control messages in the buffer.
This is missing from the current recvmsg implementation.
This commit aims to fix this by updating msg_controllen each time control
data are added to the buffer.
This commit also fixes cases where the msg_controllen is cleared
incorrectly.

TX time tracing tells how long it took from network packet
creation to when the stack got rid of it.
So the network stack allocates net packet, this is the
start time. The end time is when the packet is fully processed (sent)
by the network device driver.

In case POLLIN is set, and no new application data has been detected,
the ztls_poll_update_ctx() should only return -EAGAIN if no other events
are available for the socket. Otherwise, the function may end up
busy-looping, in case for example POLLOUT is also monitored for the
socket.
Current check verifying that was wrong, as it caused to function to
return -EAGAIN even if some other events could've been reported for the
socket.

The memory allocation for socketpairs is not conformant to the new
MEM_POOL_ADD_SIZE_ mechanism for allocating heap memory.
Specifically CONFIG_NET_SOCKETPAIR_HEAP can not be selected unless
the user has specified CONFIG_HEAP_MEM_POOL_SIZE. We should be
using MEM_POOL_ADD_SIZE_ to add to the heap if the user wants to
use it for socketpair allocation.
Additionally increase the size of pre-allocated sockets to 8 from 1
to support larger devices by default, taking into consideration the
required socketpairs and buffer sizes when using
WIFI_NM_WPA_SUPPLICANT.

Allocating FD before pulling the new connection from the fifo can lead
to busy looping in certain cases. If the application keeps calling
accept() on a listening socket after failing to allocate new FD for the
incoming connection, it'll start busy looping, as will report POLLIN in
such case (as the new connection is still on the queue), but it'll
consistently fail with ENFILE.
This can be avoided by trying to allocate new file descriptor only after
new connection has been pulled from the fifo. That way, if we fail to
allocate the file descriptor, the incoming connection will be dropped,
which seems correct given we don't have enough resources to service it.

As found in PR #75525, we should not modify the polled fd array
in multiple places. Because of this fix, the async version of
the socket service could start to trigger while it is being handled
by the async handler. This basically means that the async version
cannot work as intended so remove its support.

pollfd array used with zsock_poll() should not be modified while inside
zsock_poll() function as this could lead to unexpected results. For
instance, k_poll already monitoring some kernel primitive could report
an event, but it will not be processed if the monitored socket file
descriptor in the pollfd array was set to -1. In result,
zsock_poll() may unexpectedly quit prematurely, returning 0 events, even
if it was requested to wait infinitely.
The pollfd arrays used by zsock_poll() (ctx.events) is reinitialized
when the service thread is restarted so modifying it directly when
registering/unregistering service is not really needed. It's enough if
those functions notify the eventfd socket used to restart the services
thread.

For each of the fdtable.h functions listed below, convert the
z_ prefixed semi-private functions to use the zvfs_ prefix.
ZVFS stands for Zephyr Virtual File System and
is intended to be a common library used by the C library,
POSIX API, Networking, Filesystem, and other areas.
There are already a few functions in fdtable.h that use the
zvfs_ prefix, so this change is mostly about unifying them in
a way that uses a suitable prefix ("namespace") so that it can
be considered a public API.

- z_fdtable_call_ioctl

Until recently, the posix api was purely a consumer of the
network subsystem. However, a dependency cycle was added as
a stop-gap solution for challenges with the native platform.
Specifically,
1. eventfd symbols conflict with those of the host
2. eventfd was excluded from native libc builds via cmake
If any part of the posix were then to select the network
subsystem (which is a legitimate use case, given that networking
is a part of the posix api), we would get a build error due to
the Kconfig dependency cycle.
As usual, with dependency cycles, the cycle can be broken
via a third, mutual dependency.
What is the third mutual dependency? Naturally, it is ZVFS
which was planned some time ago. ZVFS will be where we
collect file-descriptor and FILE-pointer APIs so that we can
ensure consistency for Zephyr users.
This change deprecates EVENTFD_MAX in favour of
ZVFS_EVENTFD_MAX.

The POSIX_MAX_FDS option does not correspond to any standard
POSIX option. It was used to define the size of the file
descriptor table, which is by no means exclusively used by
POSIX (also net, fs, ...).
POSIX_MAX_FDS is being deprecated in order to ensure that
Zephyr's POSIX Kconfig variables correspond to those defined in
the specification, as of IEEE 1003.1-2017. Namely,
POSIX_OPEN_MAX. CONFIG_POSIX_MAX_OPEN_FILES is being deprecated
for the same reason.
To mitigate any possible layering violations, that option is
not user selectable. It tracks the newly added
CONFIG_ZVFS_OPEN_MAX option, which is native to Zephyr.
With this deprecation, we introduce the following Kconfig
options that map directly to standard POSIX Option Groups by
simply removing "CONFIG_":
* CONFIG_POSIX_DEVICE_IO
Similarly, with this deprecation, we introduce the following
Kconfig options that map directly to standard POSIX Options by

In order to maintain parity with the current feature set, we
introduce the following Kconfig options.
* CONFIG_POSIX_DEVICE_IO_ALIAS_CLOSE
* CONFIG_POSIX_DEVICE_IO_ALIAS_OPEN
* CONFIG_POSIX_DEVICE_IO_ALIAS_READ
* CONFIG_POSIX_DEVICE_IO_ALIAS_WRITE
Gate open(), close(), read(), and write() via the
CONFIG_POSIX_DEVICE_IO Kconfig option and move
implementations into device_io.c, to be conformant with the
spec.
