rawmemchr: modernize and simplify
* lib/rawmemchr.c (HAVE_RAWMEMCHR): Assume it’s not defined;
otherwise this file would not be compiled. Include limits.h,
stdalign.h, stdint.h, verify.h.
(rawmemchr): Prefer uintptr_t to unsigned long and to size_t when
it’s the better type. Verify that longword lacks padding. Use
alignof rather than sizeof when checking alignment. Simplify by
assuming C99 decl-after-statement, and by using multiplication
rather than repeated shifting and OR (modern compilers can
optimize the multiplication if needed). Avoid unnecessary casts.
Don’t assume CHAR_WIDTH is 8. Convert back and forth between void *
to suppress bogus GCC warnings about alignment. Omit a
duplicate assignment to char_ptr.
* modules/rawmemchr (Depends-on): Add stdalign, stdint, verify.
