5d643f4b00 net: sockets: Update msg_controllen in recvmsg properly
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.

Fixes #77303

a679dd9578 net: tracing: Add RX time tracing
RX time tracing tells how long it took from network packet
creation to when the stack got rid of it.
So the network device driver allocates net packet, this is the
start time. The end time is when the packet is fully processed.
Currently the limitation is that the RX time duration is used
for network packets that are tied to an open socket.

94b1f443ac net: sockets: Allocate FD after receiving connection in accept()
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.

93973e2ead net: sockets: move poll implementation to zvfs
Move the implementation of zsock_poll to zvfs_poll. This allows
other types of file descriptors to also make use of poll()
functionality even when the network subsystem is not enabled.

Additionally, it partially removes a dependency cycle between
posix and networking by moving functionality into a mutual
dependency.

9ada52f060 fdtable: replace z_ prefix with zvfs_ for fdtable.h functions
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_alloc_fd
- z_fdtable_call_ioctl
- z_finalize_fd
- z_finalize_typed_fd
- z_free_fd
- z_get_fd_obj
- z_get_fd_obj_and_vtable
- z_get_obj_lock_and_cond
- z_reserve_fd

- `SO_TIMESTAMPING` socket option has `SOF_TIMESTAMPING_RX_HARDWARE`
  option enabled for that socket

Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`

continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.

Updated the includes path of in-tree sources accordingly.

a150380d65 net: tcp: Implement Keep-alive support
When a TCP connection is established, if there is no data exchange
between the two parties within the set time, the side that enables
TCP Keep-alive will send a TCP probe packet with the same sequence
number as the previous TCP packet. This TCP probe packet is an empty
ACK packet (the specification recommends that it should not contain
any data, but can also contain 1 nonsense byte, such as 0x00.). If
there is no response from the other side after several consecutive
probe packets are sent, it is determined that the tcp connection has
failed, and the connection is closed.

The keep-alive default parameters are aligned with Linux defaults.
