qapi: add QAPI visitor core

Browse source 
Base definitions/includes for Visiter interface used by generated
visiter/marshalling code.

Includes a GenericList type. Our lists require an embedded element.
Since these types are generated, if you want to use them in a different
type of data structure, there's no easy way to add another embedded
element. The solution is to have non-embedded lists and that what this is.
