Dungeons (PPSA16064) calls select on descriptor 0 and stopped with
"select on descriptor 0 (not a libSceNet socket) not implemented".
Descriptor 0 is now never readable and descriptors 1 and 2 are always
writable, as for a console title with no input. The assumption is in
TechnicalDebt next to the termios entry for the same descriptors.

select passed every descriptor it was given to the libSceNet socket poller
and aborted on any it did not know. A title that selects on its
/dev/urandom descriptor (Dungeons, PPSA16064, aborts right after opening
it) stopped with "select on descriptors that are not libSceNet sockets".
On FreeBSD the random device is always readable and writable, so these
descriptors are now answered without the poller, and a ready one makes
the socket poll return at once.

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.
On a host without IPv6, socket(AF_INET6) fails with EAFNOSUPPORT, so
guest_sce_net aborted at its first IPv6 socket and never ran the TCP,
UDP, epoll, sendmsg/recvmsg, resolver and NetCtl checks after it.
When sceNetSocket reports guest EAFNOSUPPORT (47) for the IPv6 socket,
skip those socket checks, run the rest of the test, and exit with 77,
which ctest reports as skipped. Hosts with IPv6 run every check.

sceHttp2GetMemoryPoolStats, sceSslGetMemoryPoolStats and
sceNetGetMemoryPoolStats threw. PPSA16064 (Minecraft Dungeons II,
Unreal Engine) queries all three while its HTTP module starts, and
aborted there.
Each library now records the pool size given at sceHttp2Init,
sceSslInit or sceNetPoolCreate and reports it with a peak and current
use of 0: the offline Http2 and Ssl models and the host-socket Net
library allocate nothing from these pools. The layouts follow the PS4
SDK's *MemoryPoolStats structures. Net returns EBADF for an unknown
pool and EINVAL for a null output, like its other pool calls; Http2 and
Ssl throw for both, as their error codes are unknown. Terminating a
context or destroying a pool forgets its size.
sceHttp2SetResolveRetry, which the title calls next, accepts and
ignores its value like the other Http2 settings. The four Http2
WebSocket exports the title imports are added as unimplemented.
guest_http2, guest_ssl and guest_sce_net check the reported sizes;
guest_sce_net also checks the null-output and unknown-pool errors.
The layout offsets the titles read are static_asserts, and guest_sce_net now
checks a canary past byte 384, distinct records, and an untouched buffer on the
EINVAL, RESOLVER_ENODNS and EBADF paths, as #1845's test did.

PS5VR (PPSA99177) stops at start-up on the unresolved import sT4nBQKUPqM;
Jelly5, Emby5 and Nuvio import it too. The call fills the 384-byte resolver
info with up to ten IPv4 records (32 bytes each, family at +16) and the record
counts at +320 and +324, from the same host lookup sceNetResolverStartNtoa
uses, now shared. Only flags 0 is implemented; other flags throw.

The host's EHOSTUNREACH was reported as ENETUNREACH (51); FreeBSD's
EHOSTUNREACH is 65, which libkernel's sockets already report. EADDRNOTAVAIL,
ENOBUFS, EISCONN, ENOTCONN and EACCES had no translation and became EIO;
they now map to 49, 55, 56, 57 and 13, as in libkernel/Socket/src/Udp.cpp.
guest_sce_net connects the connected client again and expects EISCONN
(0x80410138); before this change it received EIO.
A non-blocking sceNetConnect that cannot complete at once must fail with
EINPROGRESS (36, 0x80410124), as FreeBSD's connect does, and a repeated call
while it is pending with EALREADY (37). On Windows, Winsock reports the
first case as WSAEWOULDBLOCK, which was translated to EAGAIN (0x80410123); on
Linux, EINPROGRESS and EALREADY had no translation and became EIO
(0x80410105). Code that waits for the connection only when connect reports
EINPROGRESS treated both as a failed connection.
guest_sce_net connects a non-blocking socket to the loopback listener and
accepts 0 or EINPROGRESS; before this change it received EAGAIN on Windows.
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.
