Add domain-specific cross-reference syntax. As of this commit, that
means new :qapi:any:`block-core` referencing syntax.
The :any: role will find anything registered to the QAPI domain,
including modules, commands, events, etc.
Creating the cross-references is powered by the QAPIXRefRole class;
resolving them is handled by QAPIDomain.resolve_xref().
QAPIXrefRole is based heavily on Sphinx's own PyXrefRole, with
modifications necessary for QAPI features.
