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.

The POSIX layer only exported init, destroy, rdlock, wrlock and unlock.
pthread_rwlock_tryrdlock, pthread_rwlock_trywrlock,
pthread_rwlock_timedrdlock and pthread_rwlock_timedwrlock now wrap the
existing scePthreadRwlock functions and accept the static initializer.
The timed variants take an absolute CLOCK_REALTIME deadline. Like
FreeBSD libthr they try the lock first and only validate abstime when
the lock is not free. A null abstime throws, as pthread_mutex_timedlock
does.
scePthreadRwlockTryrdlock and scePthreadRwlockTrywrlock return EBUSY
when the caller already holds the write lock instead of calling into
std::shared_timed_mutex, where that is undefined behaviour.

pthread_barrier_init threw for any non-null attributes object, and no
function could create one. Add pthread_barrierattr_init, _destroy,
_getpshared and _setpshared after FreeBSD libthr, and let
pthread_barrier_init take the object.
PTHREAD_PROCESS_SHARED still throws in pthread_barrierattr_setpshared:
FreeBSD 9.0 rejects it and 11.0 accepts it.

The merge brought a NotImplemented scePthreadOnce_nid_postfix next to the
existing scePthreadOnce. The NID patcher gives the NID to the postfixed
symbol, so the stub replaced the working export and the title aborted at
its first once-initialisation.

Brings in main up to 9958d26 (homebrew runtime, POSIX wrappers in
libkernel, sce_module guest modules and --skip-sce-module, the --to-intel
general pipeline, libSceRandom, libSceRtc, libScePosixForWebKit,
libRenoirCore, test wiring).
Resolutions where both sides implemented the same thing:
- libkernel pthread: main's structure (lazy static initialisation,
destroyed markers, MutexOperations/CondOperations, mutex protocol and
condattr clock) with this branch's TimedWait deadlines and condition
(precise timed lock/wait on Windows), wait tracing, the adaptive mutex
type 4, POSIX default ERRORCHECK mutexes, EDEADLK/EPERM results instead
of throws, and condition clocks honoured for absolute timeouts.
- libc locale: the guest Dinkumware ABI (_Locimp, facet vtables, short
ctype/case tables, locale ids, stream storage) is kept because guest code
inlines those layouts; main's C character functions are kept on top.
- libc stdio/strings/math: main's stream functions (guest FILE status
sync), strerror/perror, remove, formatting, string and math exports win
over this branch's duplicates.
- libc paths: main's working directory with this branch's path aliases
resolved on the normalised guest path.
- libkernel file: this branch's sceKernel* results as SCE errors, main's
POSIX wrappers and both fstat helpers.
- relinker: this branch's stub lowering keeps its trampolines through the
main executable path; guest modules refuse lowerings that need stubs.
- AGC driver: main's rendering wait is executed by this branch's workers.

libkernel: a TimedWait service for condition variables, semaphores, event flags, rwlocks and
equeues with the scheduler tick; mutex/cond/sem corner cases the title hits; job worker
affinity is opt-in (APS5_JOB_AFFINITY). libc: calloc/realloc heap slot swap, a default
terminate handler with a backtrace, CPU topology helper. libSceRtc export fixes with tests.
libSceVideoOut: APS5_NO_PAD_INPUT ignores host input for unattended measurements,
APS5_FLIP_QUEUE_WAIT keeps a stalled process alive for a debugger. ApplicationHeap and
GuestRtc tests wired into the test build.

- libc: reserve guest memory in one arena below the PS5 map limit with
MEM_WRITE_WATCH (GuestArena) and a caching guest heap; the allocation
registry gains a generation counter, an invalidator callback for the
driver's page cache and a pin waiter for leased ranges. This replaces
the fault-based GuestMemoryTracking/GuestMemoryBacking layer, whose
files are removed.
- libkernel: mmap/mprotect/munmap on the arena, flexible memory budget,
real sceKernelVirtualQuery; POSIX pthread layer, rwlocks, timed locks,
TSD, event flags; 0.5 ms scheduler tick and high-resolution sleeps;
TSC/clock/time functions; file APIs return SCE errno codes; the APR
file-streaming API.
- libc: vectored crash reporter with backtraces for fatal exceptions,
SIGABRT, UCRT invalid parameters and process exit; SSE4a EXTRQ/INSERTQ
emulation for Intel hosts; %ls/%lc/%S/%C with the guest's 16-bit
wchar_t; hand-written setjmp/longjmp for the guest jmp_buf; a path
alias table for short save-data mount points; more string, stdio and
math exports.
