- strtol, strtoul, strtoll, strtoull and strtouq return 0 for a base
outside 0 and 2 to 36, leave the end at the start and set EINVAL;
strtoimax, strtoumax, _Stoull, _Stoul and the wide forms do the same
without errno.
- A 0x prefix with no hexadecimal digit after it (base 0 or 16) is no
conversion: the end stays at the start of the string.
- wcstol, wcstoll and wcstoimax take one sign, convert the rest with
wcstoull and clamp to the signed range with ERANGE, so "- 1" is -1
and "+\t-1" overflows.
- atoi, atol and atoll truncate strtoull's result.

swscanf (HNnWdT43ues) runs the swscanf_s scanner without the buffer
size arguments after %s, %c and %[, as FreeBSD's swscanf.c passes its
arguments to vswscanf. Both entry points share one engine with a flag
for the sizes; swscanf_s behaves as before.
Title: PS5CEMU-HAR PPSA99360 imports swscanf from libSceLibcInternal.prx
(import audit with --trap-sdk-syscall-stubs, registry index 292, right
after pthread_setaffinity_np at 276). Predicted stop line once
pthread_setaffinity_np resolves, without this change:
FAIL: unresolved ELF import HNnWdT43ues (swscanf) from libSceLibcInternal.prx
NID from tools/nid_names.py, confirmed in shadPS4 aerolib.inl:51950
(e0a466753a1a). Prototype in ps5-payload-dev include/freebsd/wchar.h:133,
export in sce_stubs/libSceLibcInternal.c:8582 (f5d40f02770e).
