Tim Starling 54ff7bf8e0 Updates for RFC: Locale-independent case conversion (#1934) ...

* Add a detailed description of what is meant by ASCII case conversion
  to strtolower() and strtoupper().
* Replace locale-related text on ucfirst(), lcfirst() and ucwords()
  with text about ASCII case conversion.
* Remove entity note.locale-single-byte since it was only used on
  ucwords().
* Add changelog entries to all the functions mentioned in the RFC.
