ee2e3dd9fc net: sockets: Provide close method for packet sockets
There was no close method implemented for AF_PACKET type
sockets. This meant that calling close() on packet socket
caused NULL pointer access.

This will allow #32949 issue to work properly.

968a3101a2 net: sockets: tls: Add support for offloaded poll
Given that the offloaded poll handling differs from the poll handling of
native sockets (entire poll function call is offloaded), some
adjustements were needed to make TLS socket work with offloaded poll
calls.

To achieve this, in case socket offloading is used, instead of jumping
directly to the offloaded poll call, a TLS wrapper for the offloaded
poll will be called. This wrapper will do additional checks at the
mbedtls level, to verify that the event is only notified to the caller
when the application data is available (i. e. not to report events
during handshake or when partial data is received, not ready to
decrypt).

d0d041d833 net: getsockname: Call via vtable instead of ioctl
Add function pointer to vtable and use that directly instead of
routing via ioctl() call. This is done as we are trying to get
rid of ioctl() calls in the system.

e98f5d37f5 net: sockets: Store socket private data into its own variable
Do not try to re-use net_context.user_data field as in many places
(like in accept) it is expected to contain pointer to net_context.
Storing the socket flags will corrupt the value. To simplify and
make things less error prone, use socket specific field in net_context
to store the socket flags.

Fixes #19191

c755be0ee7 net: socket: The socket flags need to use uintptr_t
The socket flags are stored in void* so we need to use uintptr_t

8be9f5de03 cleanup: include/: move misc/fdtable.h to sys/fdtable.h
move misc/fdtable.h to sys/fdtable.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

a9a2b3ea91 net: sockets: Add socket api to support AF_PACKET
This commit adds packet socket support to socket api.
This version supports basic packet socket features.
Protocol family is AF_PACKET, type of socket is
SOCK_RAW and proto type is ETH_P_ALL. The user will
receive every packet (with L2 header) on the wire.
For TX, the subsystem expects that the user has set
all the protocol headers (L2 and L3) properly.

Networking subsystem doesn't verify or alter the headers while
sending or receiving the packets. This version supports packet
socket over Etherent only. Also combination of other family
and protocols doesn't work (i.e. Application can not open
packet-socket and non packet-socket together).

ee0b61fff8 net: sockets: Rework poll to support ioctl helper commands
This commit reworks socket poll implementation to support multiple
socket implementations.

To achieve that, two ioctl poll helper requests were added:
ZFD_IOCTL_POLL_PREPARE and ZFD_IOCTL_POLL_UPDATE. The poll
implementation calls ioctl with these requests for each socket
requested in the fds table.

The first request is responsible for preparing k_poll_event objects
for specific socket. It can request to skip waiting in k_poll by
returning EALREADY through errno.

The latter request is responsible for processing outcome of k_poll for
each socket. It can request to retry the k_poll by returning EAGAIN
through errno.
