block.c has a useful macro QAPI_LIST_ADD() for inserting at the front of any QAPI-generated list; move it from block.c to qapi/util.h so more places can use it, including one earlier place in block.c, and rename it to something more obvious (since we also have a lot of places that append, rather than prepend, to a list). There are many more places in the codebase that can benefit from using the macro, but converting them will be left to later patches. In theory, all QAPI list types are child classes of GenericList; but in practice, that relationship is not explicitly spelled out in the C type declarations (rather, it is something that happens implicitly due to C compatible layouts), and the macro does not actually depend on the GenericList type. We considered moving GenericList from visitor.h into util.h to group related code; however, such a move would be awkward if we do not also move GenericAlternate. Unfortunately, moving GenericAlternate would introduce its own problems of declaration circularity (qapi-builtin-types.h needs a complete definition of QEnumLookup from util.h, but GenericAlternate needs a complete definition of QType from qapi-builtin-types.h).
