5408c10c37 Don't normalize namespace URIs in XPointer xmlns() scheme
Namespace URIs should be compared without escaping or unescaping:

https://www.w3.org/TR/REC-xml-names/#NSNameComparison

Fixes #289.

9ab01a277d Fix XPointer paths beginning with range-to
The old code would invoke the broken xmlXPtrRangeToFunction. range-to
isn't really a function but a special kind of location step. Remove
this function and always handle range-to in the XPath code.

The old xmlXPtrRangeToFunction could also be abused to trigger a
use-after-free error with the potential for remote code execution.

Found with afl-fuzz.

Fixes CVE-2016-5131.
