[Qemu-devel] [PATCH v3 for-4.0 5/9] test-string-input-visitor: Add more tests

[David Hildenbrand <david@redhat.com>]

Test that very big/small values are not accepted and that ranges with
only one element work. Also test that ranges are ascending and cannot
have more than 65536 elements.

Rename expect4 to expect5, as we will be moving that to a separate ulist
test after the rework.
