[F&O] missing fn:prefix-from-QName

Now that the prefix is a compoent of a QName,
it seems there should be a fn:prefix-from-QName function,
with the obvious semantics.

It is not strictly needed, since it is possible to
portably implement prefix-from-QName by casting the
QName to an xs:string and then looking for a ':'.
However, fn:prefix-from-QName is the low-level
"extractor" function that logically belongs in
the standard fn namespace.
