grok_atoUV: allow non-C strings and document
This changes the internal function grok_atoUV() to not require its input
to be NUL-terminated. That means the existing calls to it must be
changed to set the ending position before calling it, as some did
already.
This function is recommended to use in a couple of pods, but it wasn't
documented in perlintern. This commit does that as well.
