6a49bb777c tree: Introduce xmlSearchNsSafe 
After the failed experiment with a static XML namespace, introduce
versions of xmlSearchNs that report malloc failures.

Optimize the no-document case by only adding the XML namespace
declaration if it wasn't found in an ancestor.

Use children pointer of entity reference nodes if available to look up
entities.
