* libc: Implement qualifier-preserving standard library functionsFaraz Vahedi7 days1-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | Several standard library functions are specified to return an unqualified pointer while accepting a pointer to a potentially const-qualified object. N3020 addresses this behaviour, discarding qualifiers due to incompatible pointer types, by introducing qualifier-preserving macros for the affected set of standard library functions. Add `__qualsel()` helper to `<sys/cdefs.h>`, implemented using the generic selection, and define qualifier-preserving macros for that set of functions in `<string.h>`, `<wchar.h>`, and `<stdlib.h>`. Macros are gated on `_STDC_VERSION__ >= 202311L && !__cplusplus`, therefore there is no behavioural change for earlier C modes or C++ translation units. The kernel is likewise unaffected, as it does not include userland headers. As function-like macros, they are transparent except at a call site where the address-of operator is applied, the macro is suppressed via `#undef`, or the identifier appears in parenthesised form; all of which cause the underlying function designator to be used instead.
