This required a massive reorg of xml/service stuff into xml/schema and
some Analysis schema/API changes.

I basically had to move all the gSOAP data serializer/deserializer
generation/compilation stuff into xml/schema, because we need to use
those things in analysis/ so we can read analysis metadata from the
filesystem in XML using the gSOAP deserializers.  BUT, then, the
xml/service stuff wants to use the code in analysis/ for interacting
with analyses.  So, chicken and egg.

Fortunately, the build already split the XML data gSOAP stubs apart
from the gSOAP RPC stubs; it was just a matter of getting all the
Makefiles and deps reoriented.

Let's see how many things break.
