scePthreadAttrGet copied the attributes of any non-null handle, so a
thread that was joined or had finished still answered 0, and a thread
that ended detached was read after its object had been freed. FreeBSD
11.4's _pthread_attr_get_np returns ESRCH for a dead or reclaimed thread,
and Monster Hunter Wilds (PPSA24191) reuses a slot of its thread table
only when scePthreadAttrGet returns 0x80020003.
After the EINVAL checks it now returns ESRCH unless the handle is a live
guest thread, and copies the fields while holding the thread registry
lock (LockLiveGuestThread), so a detached thread exiting during the call
is not freed under the copy. GuestThreadIsLive uses the same lookup.
pthread_attr_get_np, which the title does not import, is left as it is;
the debt entry records the difference.

FreeBSD's libthr rejects a null sched_param and, under SCHED_FIFO or
SCHED_RR, a priority outside sched_get_priority_min..max with ENOTSUP,
and a policy outside SCHED_FIFO..SCHED_RR with ENOTSUP. The wrappers
returned EINVAL for the null parameter and stored any priority or
policy.

On a PS5 (firmware 13.60) scePthreadAttrSetsolosched and
pthread_attr_setsolosched_np accept only 0 and 16; every other value
returns ENOTSUP and keeps the stored one. The SCE set and get calls
return EINVAL for a null or uninitialized attribute instead of throwing.

The POSIX alias takes (attr, int), returns EINVAL (22) for a null or
uninitialized attribute like the other pthread_attr setters, and
stores the value through scePthreadAttrSetsolosched, returning its
result in errno form. The signature and the stored int follow the SCE
twin in KytyPS5 and sharpemu; PS5PCEM implements the alias the same
way. The value is not applied to scheduling, recorded in TechnicalDebt.
Returnal (PPSA01285 v03.000.005) stops on it after eager binding
(#2872, #1155):
what(): pthread_attr_setsolosched_np_nid_postfix not implemented
LEGO Horizon Adventures (PPSA14632, #734) and Palworld (PPSA23126,
#2598) import it.

scePthreadAttrGet wrote priority 700 and left the affinity of the
destination untouched, whatever the thread was created with or set to
afterwards. It now reports the values the thread holds, as
pthread_attr_get_np already does.
