Subject: [PATCH] xmlcatalog: new class to update the XML catalogue

This is a new class to handle recipes that need to add/remove entries in the XML
Catalog(ue)[1].  In the future it will handle updating the catalogue on the
target, but the immediate requirement is during the build so currently this only
works with native recipes.

Note that as this is a new class and target use hasn't been implemented yet, it
is possible that the behaviour of this class will change.
