Resync my tree with the trunk. Adds support for coercing trees to xml infosets in particular for lxml (still need to wire up the tests) and some speed improvements in the parser. Big apologies for the large checkin, there are some regressions in the liberal xml parser and the sanitizer that need to be fixed.
