Main's #9573 implements scePthreadResume right after the
scePthreadMutexattrSetkind stub this branch removes from libkernel_sys;
the merge takes main's scePthreadResume and leaves the stub out.
Main's public-header audit wants one header declaration per export, so
the merge declares this branch's scePthreadMutexattrSetkind,
scePthreadMutexattrGetkind and pthread_rwlockattr_settype_np in
libkernel's Api.hpp, drops their stub declarations from libkernel_sys's
Api.hpp, has Mutex.cpp take sceKernelError from libkernel's Api.hpp,
and has the test include the libkernel headers instead of its own
declarations.
The firmware disassembly (the real Sony libScePsml.sprx inside PPSA20397)
shows scePsmlMfsrInit returning 0x8A810012 before touching the initialized
flag when sceKernelIsTrinityMode is 0, so on the modelled console every MFSR
call correctly stays uninitialized instead of reaching the unimplemented
dispatch path. The shared-resources pair likewise returns 0x8A81000D for
disallowed types and 0x8A810015 while a shared-resources object already
exists.
Priorities outside the supported band and the calling process's own pid are unverified and are no longer pinned to throw. The worker test now sets a priority different from the caller's and checks both, so a no-op or a shared value fails.
Two stream send behaviours of XNU differ from FreeBSD and Linux:
- MSG_DONTWAIT does not keep a stream send on a blocking socket from
waiting for buffer space; XNU only skips the wait for the send buffer
lock. A 16 MiB send to a slow peer blocked until the peer went away.
A MSG_DONTWAIT transfer now also passes XNU's MSG_NBIO (0x20000), which
makes one call non-blocking: the send queues what fits and returns that
count, or EAGAIN when nothing fits.
- A blocking stream send that fails after queuing data, for example when
sceNetSocketAbort shuts the socket down, returns only the error, where
Linux returns the bytes queued. A blocking stream send now goes to the
host in sends of 64 KiB and reports the bytes of the sends that
completed when a later one fails, as #8658 does.
The debt entry records the undocumented flag and the bytes that a failing
64 KiB send queued but does not report.

std::filesystem::status does not follow a Windows symbolic link under
MinGW, so the lookup chflags makes saw a link whose target is missing as
an existing file and returned 0. A reparse point in the last component
is now looked up through the target with the guest stat, as FreeBSD 11.4's
namei follows it: a missing target gives ENOENT, and a trailing slash
after a link to a file gives ENOTDIR.

sceNetEpollCreate fails with EINVAL for a null name or non-zero flags,
sceNetResolverCreate and sceNetGetMacAddress for non-zero flags, and
sceNetResolverStartNtoa, before any other check, for a negative timeout
or retry count or a flag bit outside 0x10001, as prosper reads the
libSceNet module. The two accepted resolver flag bits are still ignored,
which the debt file now records.
An image_store with DIM 2D_ARRAY through a 1D T# had no runtime image
mode, so the dispatch stopped with "image descriptor is incompatible
with the static runtime image interface". #2348 added a 1D mode for
DIM 2D stores only.
Write-only 2D-array storage images now get the same 1D mode as the 2D
case. On RDNA2 (gfx1036, hardware oracle) such a store writes texel x
and ignores y when the slice is 0, and writes nothing for any other
slice, with DEPTH 0 or 3, so the store is skipped unless the slice is 0.
New execution test agc_driver_image_store_line_through_plane_array.

A block that ended in s_code_end fell through to the next block. With
undecodable words skipped after s_code_end, that made a later branch
target a fall-through successor of s_code_end. The graph now starts a
block at the next decoded instruction after s_code_end and ends the
s_code_end block with a return, as it does for s_endpgm.
