FreeBSD's soreceive leaves the sender unset for a stream socket, so recvfrom
returns an address length of 0 (kern_recvit). The guest call formatted the empty
host address as a 28-byte AF_INET6 sockaddr and reported length 28. Report
length 0 when the host returns no AF_INET or AF_INET6 sender, as recvmsg does.
Winsock fails send, sendto and sendmsg on a socket shut down for writing
with WSAESHUTDOWN, which neither Windows error map handled, so libkernel
and libSceNet reported EIO. FreeBSD reports EPIPE there, and the Linux
maps already translate the host's EPIPE to 32. Map WSAESHUTDOWN to 32
in both.
send, sendto and sendmsg rejected every flag with EOPNOTSUPP, so callers
that pass FreeBSD's MSG_NOSIGNAL (0x20000) could not send at all. Accept
it: Windows sockets never raise SIGPIPE, and on Linux it maps to the
native MSG_NOSIGNAL. Other flags still fail with EOPNOTSUPP.
DOOM (PPSA99666) sends its upload server replies with MSG_NOSIGNAL and
closed every connection without an answer.

The Linux branch of NativeError lacked five codes the Windows branch
already translates, so they fell through to EIO. bind on a bound socket
and accept on a socket that is not listening set errno to 5 on Linux
and to 22 on Windows.

- Enhanced the network control library to check for host addresses and update connection states accordingly.
- Added support for socket operations including connect, listen, accept, send, and recv in the UDP and TCP socket implementations.
- Introduced error handling for various socket operations, ensuring proper feedback for unsupported actions.
- Created comprehensive tests for both TCP and UDP socket functionalities, validating the expected behavior of the network stack.
- Refactored existing code to improve clarity and maintainability, including the removal of unused functions and the addition of necessary error checks.
