Fix handling of XML-1.0 XML namespace declaration

Usually 'xml' namespace for XML-1.0 declaration does not need
to be carried but Mike Hommey raised the problem that the SVG
XSD file fails to parse due to a mishandling.
- SAX2.c: failure to create a namespace should not be interpreted
  as a memory allocation error
- tree.c: document better xmlNewNs behaviour, and fix it in the
  case the 'xml' prefix is being used.
