[Mondrian] DynamicDatasourcesXmlaServlet

[Luc Boudreau]

Patrick,

The 4.0.X branch underwent major refactoring and is likely to have some
nasty hidden bugs. It also introduces a new schema grammar (but upgrades
pre-4.0 schemas in the background). Julian might know better than me the
state of the 4.0 branch.
