read, write, _read and _write on a guest socket descriptor went to the
host, which has no such descriptor, so sceKernelRead and sceKernelWrite
threw. They now reach the socket as recv and send without flags, with
the socket layer's errno (EAGAIN 35, EPIPE 32, EBADF 9), a zero-length
read returns 0 as dofileread does, and the two sceKernel forms return
the kernel error for the same cases. The host's SIGPIPE on EPIPE, a
write above INT_MAX bytes, readv, writev and the positioned forms are
recorded in TechnicalDebt.
OpenSSL's QUIC notifier signals its socketpair with write and read.

The status layout is shadPS4's OrbisGameLiveStreamingStatus2 (72
bytes). Live streaming is not supported, so the call reports that no
stream is on air, with an invalid user id; a null status throws.
Uncharted: Legacy of Thieves Collection (PPSA05684) stopped at sceGameLiveStreamingGetCurrentStatus2.
Two different vertex programs that compute the same position give
bit-identical depth on the GPU, which a depth pre-pass followed by an
equal-or-greater redraw relies on. Without Invariant, a Vulkan driver may
compile the same position arithmetic differently in each shader (for
example contracting into an FMA in only one), so the redraw fails the
depth test.
Decorate the gl_PerVertex Position member and the mesh shader's Position
output Invariant, and check both in a new recompiler test.

msync follows FreeBSD 11's kern_msync and vm_map_sync over the guest's
mappings as sceKernelVirtualQuery reports them: the address is rounded
down to the page, a range that wraps and MS_ASYNC with MS_INVALIDATE are
EINVAL, an unmapped start or page is ENOMEM, and length 0 checks the
mapping that holds the address. The guest has no file mappings, so a
successful call has nothing to write back. MS_INVALIDATE on a mapped
range throws, since FreeBSD's EBUSY for mlocked pages needs lock state
that is not tracked.

The IME panel cannot be open while sceImeOpen is unimplemented, so the
query returns SCE_IME_ERROR_NOT_OPENED and leaves the output untouched,
like sceImeSetCaret, sceImeSetText and sceImeSetTextGeometry. As with
sceImeSetCaret, the closed panel is reported before a null output.

The guest's unsigned long is 64 bits. _Stoul was declared with the
host's unsigned long and returned std::strtoul, which are 32 bits on
Windows (LLP64): "4294967296" clamped to 4294967295 with ERANGE and
"-1" gave 0xffffffff, so a guest std::stoul threw out_of_range on values
the console accepts. It now returns std::uint64_t from std::strtoull,
as strtoul_nid_postfix and _Stoull already do; on Linux nothing changes.
The binary-prefix check stays in front of the host call.
Reported in #2424 by AchrafReyani; the same change was proposed in #2442
by SurajKhanna, whose two guest_math cases are taken here. Folded in at
MarcZX100's suggestion on #1459.

Both exports are imported by titles that link libSceAudio3d; without them the loader fails with an unresolved import before the title runs. Following the offline model, object attributes are validated but produce no audio and PortFlush drops the frames queued by sceAudio3dPortAdvance.
Pan follows the PS4 firmware 11.00 libSceNgs2.sprx: the speaker layout
from the init angles, then each param's angle and distance into a
volume matrix for the voice. Every param is checked before anything is
written, and angles too large to wrap throw. The pan functions are
exported from the existing Voice.cpp export block.

wcstol, wcstoll, wcstoul and wcstoull parse the ASCII prefix of the
guest's UTF-16 text with std::strtoll and std::strtoull, which glibc 2.38
and later bind to the C23 __isoc23_* functions: wcstol(u"0b101", &end, 0)
returned 5 with the end pointer after the whole string. They now check
StopAtBinaryPrefix_nid_no_patch first, like the narrow functions, and the
end pointer maps back through ParseAsciiPrefix as before.

C17 has no binary prefix: with base 0 or 2, strtol("0b101", &end, base)
reads the subject "0", returns 0 and leaves end at the 'b'. With glibc
2.38 or later, g++ (which defines _GNU_SOURCE) binds std::strtoll,
strtoull, strtoul, strtoimax and strtoumax to the C23 __isoc23_*
functions, which accept 0b/0B: the Linux exports returned 5 and
consumed the whole string. The Windows UCRT already follows C17, so the
same guest call gave different results on the two hosts.
strtol, strtoul, strtoll, strtoull, _Stoull, strtoimax, strtoumax and
_Stoul now return 0 with the end pointer after the '0' when, after
white space and an optional sign, the text starts with 0b or 0B and a
binary digit, in base 0 or 2. Everything else still goes to the host
function. The scanf family's %i has the same glibc behaviour; it is
recorded in TechnicalDebt.
