The include directive permits modular QAPI schemata, but the generated
code is monolithic all the same.  To permit generating modular code,
the front end needs to pass more information on inclusions to the back
ends.  The commit before last added the necessary information to the
parse tree.  This commit adds it to the intermediate representation
and its QAPISchemaVisitor.  A later commit will use this to to
generate modular code.

New entity QAPISchemaInclude represents inclusions.  Call new visitor
method visit_include() for it, so visitors can see the sub-modules a
module includes.

Note that unlike other entities, QAPISchemaInclude has no name, and is
therefore not added to entity_dict.

New QAPISchemaEntity attribute @module names the entity's source file.
Call new visitor method visit_module() when it changes during a visit,
so visitors can keep track of the module being visited.

The generators' conversion to visitors (merge commit 9e72681d)
changed the processing order of entities from source order to
alphabetical order.  The next commit needs source order, so change it
back.

We have two representations of sections without a name: the main
section uses name=None, the others name=''.  Standardize on name=None.

We would like to use a same QObject type to represent numbers, whether
they are int, uint, or floats. Getters will allow some compatibility
between the various types if the number fits other representations.

Add a few more tests while at it.
