[Qemu-devel] [PULL 08/32] test-string-input-visitor: Split off uint64 list tests

[Markus Armbruster <armbru@redhat.com>]

From: David Hildenbrand <david@redhat.com>

Basically copy all int64 list tests but adapt them to work on uint64
instead. The values for very big/very small values have to be adapted.
