Implement scePthreadGetschedparam and scePthreadSetschedparam on top of
the thread priority, POSIX utimes and fsync on top of sceKernelUtimes
and sceKernelFsync, and sceUserServiceGetAccessibilityZoomFollowFocus
like the other accessibility queries. Add the remaining imports of
PPSA12544 as unimplemented exports and record unknown NIDs and
signatures in the technical debt.

scePsmlMfsrGetContextBufferRequirement1100, scePsmlMfsrCreateContext1100
and scePsmlMfsrGetDispatchMfsrPacket1100 were not exported, so a title
importing them failed to load.
In Sony's libScePsml all three return 0x8A810001 (not initialized)
without writing their outputs until scePsmlMfsrInit has succeeded.
AnyPS5's scePsmlMfsrInit throws, so that is the only state a title can
reach, and the three calls now return that error.
The existing stubs for scePsmlMfsrInit, scePsmlMfsrReleaseContext and
scePsmlMfsrGetDispatchMfsrPacketSizeInDwords get their real names and
still throw. libScePsml_debug gets a CMakeLists.txt for the new
guest_psml test.

A title's own libc.prx implements __cxa_thread_atexit and the
destructor pass of exit() through _sceLibcInternalThreadAtexit and
_sceLibcInternalThreadDtors. Its __cxa_finalize calls
_sceLibcInternalForceTlsDestructor.
Destructors are kept per thread and run newest first, including those
registered while they run, as FreeBSD's __cxa_thread_call_dtors does.
A null destructor or one outside every loaded image throws instead of
being skipped. The first registration installs the pass as the
libkernel thread exit hook, so it runs on every guest thread before
the thread can be joined. _sceLibcInternalForceTlsDestructor throws.

IntrusivePtr<T> is three pointers: object, deleter, LibContext. The default
constructors zero them, the copy constructors copy them and take a reference
on the object, operator-> and operator* return the object, and the destructors
drop a reference and hand the object to the deleter when it was the last one.
The last-reference release of a pointer without a deleter needs the object's
destructor and the LibContext memory pool and still throws.

The constructor was a silent stub that left the guest object
uninitialised and c_str threw. The constructor now writes the 0x20-byte
object, c_str returns the buffer or an empty string, and the destructor
throws for a non-null buffer, whose release needs the LibContext
allocator.

Report the process time at which sceAudioOutOutput or sceAudioOutOutputs
accepted the port's last block. A port that never output reports 0, and
waiting with a null pointer does not move the time.

The DCB variant threw "not implemented" while the ACB one wrote a
5-dword packet. Both now go through Agc::Command::WritePrimeUtcl2 and
the size query returns 20 bytes.

Format through the shared wide formatter, truncate to the buffer and
return the full length, as C11 K.3.9.1.3 specifies. A null buffer or
format, a zero or oversized n, %n and a null %s argument are
runtime-constraint violations that return a negative value.

v_ceil/floor/trunc/rndne/fract/sqrt/rsq/rcp/rcp_iflag/log/exp/sin/cos
(f32 and f16) and v_frexp_mant_f32 left NaN, invalid, zero and infinite
results to the driver: signalling NaNs came back unquieted, lavapipe lost
the NaN sign and payload, invalid results were +NaN instead of -NaN, f32
sin/cos at whole and half cycles returned tiny values instead of +0, and
v_fract_f16 of a tiny negative rounded up to 1.0.
Adds an execution test for the 27 opcodes with expected values from
hardware; approximate ops are compared with tolerances from the Vulkan
precision table.

A filter_type naming a subset of the PNG filters used only the first
filter of the mask, because stb's writer is either fully adaptive or
forced to one filter. Decoder::Png::Encode now takes the set of allowed
filter types, filters the rows and writes the chunks itself, and keeps
stb for deflate only. Output for the all-filters and single-filter
cases is unchanged.

SHA1RNDS4/NEXTE/MSG1/MSG2 with a memory source made `--to-intel` fail
the whole relink. The stub now spills a scratch xmm, loads the operand
into it with the unaligned load already used for SHA-256 and runs the
register-form lowering. The SHA1RNDS4 immediate is read after the SIB
byte and displacement. RIP-relative operands still fail: the stub runs
at a different address.

Return the kerning between two character codes at the render scale of
the font, the one set by sceFontSetupRenderScalePixel and
sceFontSetupRenderScalePoint, and fail with NOT_BOUND_RENDERER when no
renderer is bound. sceFontGetKerning keeps its behaviour and shares the
FreeType lookup.

s_setreg_b32 has no effect, so a read of the MODE round fields after it
wrote another mode still reports round to nearest even, the rounding the
recompiled code uses. The refused HW_ID test row is named as hardware
register 4, which has no name on gfx10.

As in ampr_emu, a counter pair starts at an even counter, and the write
commands take a non-null, 8-byte aligned address; others return EINVAL.

sceAmprCommandBufferWaitOnAddress took (address, reference, mask,
compare) and WaitOnCounter (counter, reference, compare), and both read
the compare value as WAIT_REG_MEM (0 always, 1 <, 2 <=, 3 ==, ...).
ampr_emu, which replaces libSceAmpr for retail titles on the console,
has (address, reference, compare, flush) and (counter, reference,
compare, flush) with the SCE compare values (0 ==, 1 > unsigned,
2 < unsigned, 3 !=), so waits were decoded as other comparisons and
could block forever or pass early.
WriteAddressFromCounterPairOnCompletion takes one counter index, not
two, and WriteKernelEventQueueOnCompletion an int id and no user data.
Counter indices above 127, compare values above 3, flush values above 1
and misaligned wait addresses return EINVAL, as in ampr_emu.

Read the MPEG audio frame header and report the frame size, channel
count, samples per channel, bitrate and sample rate. The signature,
the result layout and the rate tables follow shadPS4's reimplementation
of the PS4 library. Requesting the original file length throws: that
lookup is not implemented.

ds_add/sub/rsub/inc/dec_u64, ds_min/max_i64/u64, ds_and/or/xor/mskor_b64,
ds_cmpst_b64/f64, ds_min/max_f64, their _rtn forms and ds_wrxchg_rtn_b64
threw in the decoder.
LDS is a 32-bit workgroup array, so the two dwords are read and written
under a lock dword placed after the guest LDS, which is cleared with a
workgroup barrier at entry. The lock is acquired and released in the same
loop iteration, so lanes of one subgroup cannot deadlock on it. Stages
whose LDS is a function variable update it directly. 64-bit GDS atomics
throw.
