  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.
