The PS5 libSceNgs2.native (firmware 3.20 and 4.03) accepts every value of the mastering gain param 0x30000004 with return code 0, clamps each level to [-32, 32] (so +-inf gives +-32) and keeps NaN, which then gives NaN samples. Ours threw on NaN and inf and did not clamp. A NaN sample in a PCM_I16L render buffer now throws, since the PS5 conversion was only measured into float buffers.

A queue that has received neither INDEX_BUFFER_SIZE nor
INDEX_ATTRIBUTES_INDIRECT since its last reset has no index limit.
Such a draw takes the CPU record path and reads each record's index
range as written, refusing a range that overflows or is not readable.
An explicit INDEX_BUFFER_SIZE of 0 still throws.
drand48 and erand48 returned the whole 48-bit state over 2^48, as FreeBSD
does. The libc.prx bundled with eleven titles returns its upper 32 bits
over 2^32, so the low 16 bits never reach the result; both functions now
do the same. The generator and the other rand48 functions are unchanged.

v_rcp_f32 and v_rcp_iflag_f32 lower to the driver's 1/x, whose low bits
differ from the console's on NVIDIA and Intel. With APS5_EXACT_RCP set,
normal inputs with normal results take the RDNA reciprocal datapath
instead: a cubic over 32 segments of the mantissa in 32-bit integer
arithmetic, the linear term rounded to nearest even, and a 2,761-entry
table of one-ULP corrections, looked up only when the dropped bits fall
next to the rounding cut (6.25 % of inputs). This reproduces all 2^23
mantissas of an RDNA2 (gfx1031) sweep. Other inputs keep 1/x.
It is off by default: the tables add about 13k SPIR-V words to each
shader that uses it.

Brings in main with #9204. The measured CP932 and CP51932 encoding rules (JIS form aliases, U+FEFF, the C1 range and U+000E) apply to those profiles only; the strict JIS X 0208 profiles keep #9204's tables.

Keep #9204's strict JIS X 0208 profiles with their SS2 and SS3 choices inside the new helpers: decodeEucJp sends the measured CP51932 profile to decodeEucJpScalar and the strict profiles to #9204's rules, and only the X0208Ss2Ss3 profile encodes JIS X 0212. The EUC-KR, UHC and Big5 UTF-8 forms decode with decodeScalarUtf8.

Keep #9108's long IPv4-mapped bind on a dual-stack datagram socket, now also for connect, on top of the measured exact-size checks; drop LongAddressError and the duplicate listening check.

scePadOpen for the system user's remote control port (type 16) returned the
DualSense handle, so scePadReadState on the "remote" reported the controller's
buttons as connected. SDL's PS5 video driver maps that port's buttons to keys,
so every Cross also arrived as Return and every D-pad press as an arrow key.
In Raptor (PPSA94002) the Return overwrote the key typed on the on-screen
keyboard before the name field read it, and Circle closed the dialog instead
of the keyboard.
The port now opens its own handle that reads no buttons with connected false,
and closes independently of the DualSense handle. Unlike the special port
handles, it stays out of KnownHandle, so calls that act on the DualSense reject
it.

DB_STENCIL_CONTROL codes 10, 11, 12 and 15 (STENCIL_AND, STENCIL_OR,
STENCIL_XOR, STENCIL_XNOR) combine the stored stencil value with
DB_STENCILREFMASK.STENCILOPVAL, as AMD_stencil_operation_extended
defines them, and threw "stencil operation N is unsupported".
Each one now becomes a single Vulkan operation with the face's write
mask narrowed to the bits it can change: ZERO for AND, INVERT for XOR
and XNOR, REPLACE with those reference bits set for OR. A face whose
other operations write other bits, OR against a compared test value bit
it would set, OR with a stencil test value export, and NAND and NOR
still throw.

Implement sceCesUcsProfileInitGb18030_2000 and sceCesUcsProfileInitGb18030_2005.
Two-byte cells are the CP936 table plus the cells that differ, and four-byte
sequences are runs over the BMP and the supplementary planes, generated from
ICU's gb-18030-2000.ucm (before ICU-8427) and gb-18030-2005.ucm with ICU's
GB 18030 ranges. The GB, MBC and MBCS string conversions accept both profiles
and produce four-byte UTF-8 and surrogate pairs for supplementary characters.
strcasecmp and strncasecmp returned the folded unsigned-byte difference,
following FreeBSD 11.4's strcasecmp.c (#3966, #9642). The libc.prx bundled
with eleven titles returns -1, 0 or 1, the sign of that difference; both
functions now do the same, and the byte-pair tests expect it.
