Previously only qstr*icmp() were tested and the test data was sent via
QString and {en,de}coding. Use a local data-type to package pointers
to actual string literals for passing to these functions that take
them. Fold the various tests involving null pointers and empty
strings into the general testing, removing from "singularity" tests,
and combine the remainders of those tests into a single test of
singular cases for QByteArray::ompare. Move all these tests to
alongside the existing tests for QByteArray::compare. Use nullptr
rather than 0 as the null string.
