Fix exponential runtime and memory in xi:fallback processing When creating XML_XINCLUDE_START nodes, the children of the original xi:include node must be freed, otherwise fallback content is copied twice, doubling runtime and memory consumption for each nested xi:fallback/xi:include pair. Found with libFuzzer.
