qapi: Record 'include' directives in intermediate representation
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.

qapi: Record 'include' directives in parse tree
The parse tree is a list of expressions. Except include expressions
currently get replaced by the included file's parse tree.
Instead of throwing away the include expression, keep it with the file
name expanded so you don't have to track the including file's
directory to make sense of it.
A future commit will put this include expression to use.

qapi: Touch generated files only when they change
A massive number of objects depends on QAPI-generated headers. In my
"build everything" tree, it's roughly 4800 out of 5100. This is
particularly annoying when only some of the generated files change,
say for a doc fix.
Improve qapi-gen.py to touch its output files only if they actually
change. Rebuild time for a QAPI doc fix drops from many minutes to a
few seconds. Rebuilds get faster for certain code changes, too. For
instance, adding a simple QMP event now recompiles less than 200
instead of 4800 objects. But adding a QAPI type is as bad as ever;
we've clearly got more work to do.
