2025-11-05	[libc] Migrate ctype_utils to use char instead of int where applicable. ↵	Alexey Samsonov
	(#166225) Functions like isalpha / tolower can operate on chars internally. This allows us to get rid of unnecessary casts and open a way to creating wchar_t overloads with the same names (e.g. for isalpha), that would simplify templated code for conversion functions (see 315dfe5865962d8a3d60e21d1fffce5214fe54ef). Add the int->char converstion to public entrypoints implementation instead. We also need to introduce bounds check on the input argument values - these functions' behavior is unspecified if the argument is neither EOF nor fits in "unsigned char" range, but the tests we've had verified that they always return false for small negative values. To preserve this behavior, cover it explicitly.
2024-12-10	[libc] move bcmp, bzero, bcopy, index, rindex, strcasecmp, strncasecmp to ↵	Nick Desaulniers
	strings.h (#118899) docgen relies on the convention that we have a file foo.cpp in libc/src/\<header\>/. Because the above functions weren't in libc/src/strings/ but rather libc/src/string/, docgen could not find that we had implemented these. Rather than add special carve outs to docgen, let's fix up our sources for these 7 functions to stick with the existing conventions the rest of the codebase follows. Link: #118860 Fixes: #118875
