- Support passing in unterminated C-strings when clamped by the size
argument.
- Pair string and it's size arguments together in IDP_NewStringMaxSize.
- Remove redundant size check which made it seem as if the string
might not be null terminated.
- Replace clamping the result of strlen(..) with BLI_strnlen,
to avoid calculating the length past the size checked.
- Add doc-string for unclamped string creation.
