libSceNet registers a socket poller with libkernel; select polls the requested descriptors through it until the timeout and rewrites the descriptor sets.
Every failing sceNet function returned -1 and left the code only in
sceNetErrnoLoc. The functions return the errno combined with
0x80410100 (SCE_NET_ERROR_*), as the resolver paths of this file
already do with RESOLVER_ENODNS and as shadPS4 and fpPS4 do for the
whole library. A title that compares the result with
SCE_NET_ERROR_EWOULDBLOCK saw a non-blocking receive without data as
an unknown failure.

sceNetSend and sceNetSendto called send and sendto without
MSG_NOSIGNAL, so a send on a connection the peer had closed raised
SIGPIPE and terminated the process. shadPS4 has sceNetSend pass
0x20000, FreeBSD's MSG_NOSIGNAL, down to sendto, so a title gets the
error back instead of a signal.
Pass MSG_NOSIGNAL on Linux and translate EPIPE, which fell through to
EIO.

- 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.
