Compiled XSLT stylesheets. Improves speed, implements forwards-compatible-parsing and handling of unknown extension-elements. Also fixes some random edgecasebugs such as recursive merged named-attribute-sets and empty strings in copy-of.

Patch mainly by sicking, but large parts also by Pike and peterv.

Tracker is bug 185797. r=Pike/sicking rs=peterv.
