[xslt] Rewrite of str:replace

[Nick Wellnhofer]

I just found an old patch of mine. It makes the str:replace extension 
function standard-conformant. See 
https://bugzilla.gnome.org/show_bug.cgi?id=569703. I committed it on top 
of my other fixes on Github.

Daniel, if you like, I can send you all my changes as single patches.
Nick
