Forwards _sceUltWaitingQueueResourcePoolCreate and _sceUltSemaphoreCreate to the existing calls, like the other underscore Ult exports. Declares sceNetShowIfconfig, sceNpWebApi2GetMemoryPoolStats, Json::Value::setNullAccessCallBack, kqueue, kevent and one pad call of unknown name without an implementation.

Report the thread's affinity mask as a 32-byte FreeBSD cpuset_t, with
FreeBSD 11's errors: ERANGE for any other set size, ESRCH for a null
thread and EFAULT for a null set.
EVO-PLAYER (PPSA99039 v0.11.0) imports it (Jb2uGFMr688) and calls it
once with a 32-byte set on pthread_self().
Relinks the ELF modules of extra directories under the module parent directory. Modules the executable or another module needs start with the executable; the others are initialized when the title loads them with sceKernelLoadStartModule, with its start arguments (Windows: __aps5_guest_initialize export; Linux: left out of DT_NEEDED).
Squashed onto main by the reviewer (history had a merge commit).
A stack base need not be page aligned (it is not on Linux), so rounding the
range down first could leave the stack and miss the stack path. The range the
guest asked for is now checked against the guest stack, and the rounded
pages are protected, as FreeBSD rounds the address down.
A thread that exits with part of its stack protected left those pages to the
next thread that reused the stack. Protected stack pages are recorded, and a
thread's stack is made readable and writable again when it is unregistered at
exit.

On Windows a guest thread runs on its host thread's stack, which is not a
registered guest allocation, so mprotect on any of its pages failed with
EINVAL. A guest that guards the bottom of its own stack (Dolphin's JIT
read-protects 64 KiB there to catch stack overflows) got an error where the
PS5 changes the protection.
A range that lies inside a live guest thread stack, with no GPU access
requested, now takes the native protection directly. Ranges that cross the
stack's bounds are still rejected.

The bundled libc.prx of PPSA21703 calls sceKernelGetModuleInfoFromAddr
with a 0x1A8-byte stack buffer and never sets st_size, so the field holds
whatever was on the stack (983040 in one run) and the call threw. The
console cannot require the field on input. The full size is still
written back. The flags check is unchanged.

On Linux every call opened /proc/self/maps and scanned it line by line with sscanf. Unity titles call it on each stack walk, and with about 900 mappings God of War Sons of Sparta (PPSA28997) spent most of its main thread there. The covering mapping is now asked of the kernel with PROCMAP_QUERY (Linux 6.11), on one descriptor opened once, as GuestMemory does; older kernels and APS5_NO_PROCMAP_QUERY keep the line scan.
The title id now comes from GetAppTitleId, so param.json has one parser and
its validation (a missing file or titleId throws). Another pid returns EPERM
and a null info returns 0 without writing, as shadPS4 does. app_id stays 1,
the running title's id in libSceSystemService, which is inferred, not
measured.
guest_app_info runs the call without param.json in a child process and
checks that the field between app_id and the title id is left alone.
