JAXP default implementation and JDK-8152063

[David M. Lloyd]

This is all for the case where the user is calling e.g. 
javax.xml.stream.XMLInputFactory#newFactory() with no arguments.  We 
need some way to choose a specific non-JDK default implementation when 
there is no service loader info on the TCCL.  Using the Layer of the 
caller of the newFactory() method would be an ideal solution from our 
perspective.
