[Qemu-devel] [PATCH v4 10/16] qapi: Support downstream enums

[Eric Blake]

Enhance the testsuite to cover a downstream enum type and enum
string.  Update the generator to mangle the enum name in the
appropriate places.

Signed-off-by: Eric Blake <address@hidden>

v4: use type_name() instead of special-casing builtins in
generate_visit_list()
