On Linux scePthreadExit called pthread_exit, whose forced unwind runs
the personality routine of every guest frame. Those resolve to
libc.prx's __gxx_personality_v0, which cannot read libgcc's unwind
context and aborts, so guest_thread_self crashed on Linux.
Record a jump target in the thread start routine and longjmp back to it
from scePthreadExit instead. Like _endthreadex on Windows, this skips
the guest frames without unwinding them; the start routine still
releases the thread normally. Threads not created by scePthreadCreate
keep the pthread_exit fallback.

Bring in the resolved#25 branch, which already carries upstream main
including boykopovar/AnyPS5#10, and re-apply the KernelErrors.hpp
refactor onto the rewritten files:
- Equeue: drop the local EQUEUE_ERROR_* constants and use the shared
SCE_KERNEL_ERROR_* names.
- Pthread Attr/Thread: drop local error constants and include
KernelErrors.hpp.
- Pthread Cond/Mutex: take upstream; they no longer define local
SCE_KERNEL_ERROR_* constants.
- Semaphore: drop KERNEL_SEMA_ERROR_* in favour of KernelErrors.hpp.

Resolve conflicts with boykopovar/AnyPS5#10 (sce module loading) and
later upstream changes.
- Pthread Cond/Mutex: take upstream. It already releases mutex
ownership across condition waits, returns ETIMEDOUT 0x8002003C, and
rejects unlocks from non-owners for every mutex type.
- Pthread Thread: keep upstream's lifecycle, Windows adoption and job
affinity; re-apply the POSIX fixes on top: reference-counted
release on join/detach/exit, self-join rejection on both platforms,
and scePthreadSelf adoption for threads not created by
scePthreadCreate.
- Semaphore: keep upstream's TimedWait::Condition and wait tracing;
re-apply sceKernelDeleteSema waking waiters with EACCES.
- Relinker: keep --windows-gui alongside upstream's --skip-sce-module,
trampoline-aware Patch signature and new Python tests.

Every lock, unlock, signal and wait took the process-wide initialisation
mutex to read the handle, serialising all guest synchronisation. The
handle is now read atomically and the lock is only taken to initialise a
static initializer or to report a destroyed object.

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.

Kernel error codes were redeclared per file under three prefixes
(SCE_KERNEL_ERROR_, EQUEUE_ERROR_, KERNEL_SEMA_ERROR_), which let wrong
values go unnoticed. Define them once as 0x80020000 | errno for errno
1..94 and use the SCE_KERNEL_ERROR_ names everywhere. Values are unchanged.

SCE kernel errors are 0x80020000 plus the FreeBSD errno. The equeue and
direct memory constants used an unrelated 0x8001xxxx range with mismatched
errno values (e.g. ETIMEDOUT was 0x80010023), so a guest checking
sceKernelWaitEqueue for SCE_KERNEL_ERROR_ETIMEDOUT saw an unexpected error.
SCE_KERNEL_ERROR_EDEADLK in Mutex.cpp held the EAGAIN value.

- scePthreadSelf returned null on Linux and for threads not created by
scePthreadCreate (including the main thread); such threads now get a
lazily adopted, non-joinable handle
- scePthreadExit on Linux skipped FinishThread, losing the join value
- detached threads on Linux were never freed; use the reference count
already used on Windows
- unlocking a recursive mutex from a non-owner was undefined behaviour;
return SCE_KERNEL_ERROR_EPERM
- scePthreadCondTimedwait did not restore the mutex owner after waking,
so another thread locking during the wait made the waiter's unlock
fail with EPERM and left the mutex locked forever
- SCE_KERNEL_ERROR_ETIMEDOUT in Cond.cpp was 0x80020062 instead of 0x8002003C

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.
