Add pthread_cond_reltimedwait_np (K953PF5u6Pc; computed with
tools/nid_names.py and matching aerolib.csv) as scePthreadCondTimedwait
with POSIX error numbers: ETIMEDOUT when the relative timeout expires,
EPERM when the caller does not hold the mutex, and the mutex held again on
return in every waiting case.
Titles: Porpoise PPSA99764 and RetroArch PPSA99169 import it.
Predicted from relink registry order, not observed: Porpoise stops with
"FAIL: unresolved ELF import K953PF5u6Pc from libkernel.prx" (registry
index 384; RetroArch index 490). No call site is resolved in the registry.
The third argument is a relative timeout in microseconds, not a
struct timespec. FreeBSD 11.4 libthr (8c639945a44588f6cfdddfb057bb5aad88735da0)
has no such function. shadPS4 (3a9f57265d28975658f1ca941daa5c879c7a74bd,
src/core/libraries/kernel/threads/condvar.cpp:229-234, 445, 467-468)
registers posix_pthread_cond_reltimedwait_np(cond, mutex, u64 usec) for this
NID and the same function for scePthreadCondTimedwait (BmMjYxmew1w), whose
microsecond argument this repository already implements. The width follows
the SCE twin's 32-bit SceKernelUseconds, as sem_reltimedwait_np does, not
shadPS4's u64. There is no timespec to validate, so no EINVAL case.

(cherry picked from commit c86ec8417d12f5b12136b0f06eae06493b0e7a62)
Add pthread_spin_init (ZMn3clnAGBA), pthread_spin_destroy (IJIggoPZExk),
pthread_spin_lock (pw+70ClLYlY), pthread_spin_trylock (rCTGkBIHfPY) and
pthread_spin_unlock (LEfMMCT+SlM). The NIDs were computed with
tools/nid_names.py and match aerolib.csv. libkernel has no scePthreadSpin*
twin in aerolib, so the calls are implemented directly, like the barrier.
Titles: Porpoise PPSA99764 and RetroArch PPSA99169 import pthread_spin_lock.
Predicted from relink registry order, not observed: after
pthread_cond_reltimedwait_np, Porpoise stops with
"FAIL: unresolved ELF import pw+70ClLYlY from libkernel.prx" (registry
index 387; RetroArch index 493). No call site is resolved in the registry.
Behaviour follows FreeBSD 11.4 libthr thr_pspinlock.c and thr_umtx.h
(8c639945a44588f6cfdddfb057bb5aad88735da0). The guest pthread_spinlock_t
holds a pointer to an allocated lock. EINVAL for a null or destroyed lock and
for a pshared other than PTHREAD_PROCESS_PRIVATE or PTHREAD_PROCESS_SHARED,
EBUSY from trylock while any thread holds the lock, EPERM from unlock by a
thread that does not hold it. libthr spins forever when the holder locks
again; that call throws here. A shared lock is allocated like a private one,
since guest code runs in one process. Recorded in TechnicalDebt.

(cherry picked from commit 13ebf7f926fa2ee1c825cb1fcf18451a8781c045)
Exports pause (EDyhWelj7UY), sigwait (mrbHXqK8wkg) and sigwaitinfo
(Uq5BGthgbl4) from libkernel. NIDs computed with tools/nid_names.py and
matched in aerolib; ps5-payload-dev/sdk f5d40f02 sce_stubs/libkernel.c
places all three in libkernel.
They throw like the merged sigtimedwait (#3430), with the same message
pattern: "sigwait: waiting for a pending signal", "sigwaitinfo: waiting
for a pending signal" and "pause: waiting for a delivered signal". In
FreeBSD 11.4 (8c639945) sigwaitinfo is kern_sigtimedwait without a
timeout (sys/kern/kern_sig.c:1212), sigwait is the same wait returning
the error number (kern_sig.c:1150, lib/libthr/thread/thr_sig.c:676-728)
and pause is sigsuspend of the current mask (lib/libc/gen/pause.c:46-56).
AnyPS5 never leaves a guest signal pending (blocked signals are dropped
in Dispatch, raise delivers at once), so there is nothing to take, and
raise, kill and pthread_kill run a handler only on the calling thread,
so nothing can end a pause.
Titles (predicted stops, registry order; not observed runs):
- Ruffle PPSA68091, observed today
"FAIL: unresolved ELF import 1t1-JoZ0sZQ from libSceLibcInternal.prx"
(sinhf, #3519), predicted next
"FAIL: unresolved ELF import EDyhWelj7UY from libkernel.prx"
(pause, call site 0x8F7266).
- RetroArch PPSA99169: pause (0x30DB1, an address table entry).
- PS5MC PPSA99420: pause (0x3BD80F6, 0x3C9E220), sigwait (0x3C9E4C7),
sigwaitinfo (0x3C9E588).
- XPSemu PPSA97358: sigwait (0xE02AEC, 0x1101294, 0x1101368), QEMU's
dummy vCPU thread and sigwait_compat thread.
guest_sigtimedwait now also checks the three throws, with an empty set,
a null info, a SIGINT raised while blocked, and that neither the output
nor the blocked mask changes. TechnicalDebt records the call sites.

Carry the implementation and regression from lucfx18's PR #2823, retaining
the original Git author. Extend the regression with a leading guard and
typed default-field checks, and record the unverified console layout.
