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.

Translate the FreeBSD pollfd layout and flags to WSAPoll on Windows and
poll on Linux. Closed socket descriptors report POLLNVAL, a timeout below
-1 fails with EINVAL and a null array with EFAULT. Non-socket
descriptors, unknown event bits, POLLPRI on Windows and an infinite wait
without sockets throw; these are recorded in TechnicalDebt.
DOOM (PPSA99666) imports poll for its upload server.

libSceNet registers a socket poller with libkernel; select polls the requested descriptors through it until the timeout and rewrites the descriptor sets.
The FreeBSD kernel ignores sa_len in a socket address passed in and sets
it from the length argument, so titles may leave it 0. Only the family
and the length argument decide the address kind now.

Both take the FreeBSD msghdr (48 bytes, iovecs of a pointer and a 64-bit
length) and run on the host sockets: sendmsg gathers the iovecs and sends
through sendto, recvmsg receives into one buffer and scatters it. A
datagram longer than the iovecs is cut and reported with MSG_TRUNC, also
on Windows where recvfrom fails with WSAEMSGSIZE. More than 1024 iovecs
fail with EMSGSIZE. No ancillary data is ever received, so recvmsg
clears msg_controllen; sending control data throws.

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.
Only the lines this branch added lose their comments; the commits before
keep them, with the reasoning behind each change, for whoever digs into
that code later.

libkernel:
- direct memory keeps its contents per physical page across unmap and
remap; a page mapped at two live addresses at once throws
- sceKernelDirectMemoryQuery answers from tracked allocations
- SCE protections read back as set, GPU and AMPR bits included
- APR prefix path resolve, file size and stat by id, positional reads,
fsync/pread/pwrite; directories open as descriptors on Windows
- sceKernelCheckReachability, getpeername, shutdown
- Dinkumware C11 threads (_Mtx_*, _Cnd_*, _Thrd_*) in the title libc
layout; any pthread stack size, rounded at thread creation
libc:
- unaddressed guest mappings go to the system-managed area from
0x2_0000_0000, leaving the application area to fixed mappings
- the process starts in /app0
- guest sscanf on Windows; a null %s prints as (null) as on FreeBSD
- localeconv, _FNan, _FDtest, _FExp, __udivti3, wcsncpy_s, aligned
operator new, _Throw_Cpp_error
Tests: direct memory following physical pages, guest formatting.
