Propagate memory errors in valuePush Currently, many memory allocation errors in xpath.c aren't propagated to the parser/evaluation context and for the most part ignored. Most XPath objects allocated via one of the New, Wrap or Copy functions end up being pushed on the stack, so adding a check in valuePush handles many cases without much effort. Also simplify the code a little and make sure to return -1 in case of error.
