Test the creation of ZIP archives bigger than 4GB and containing files bigger than 4GB. They are marked as EXPENSIVE because they take quite a while and because the first one needs a bit more than 4GB of disk space to store the resulting archive.
The big archive in the first test is made up of a tree containing thousands of copies of a small file. Yet the test has to write out the full archive because unzip doesn't offer a way to read from stdin.
The big file in the second test is provided as a zipped pack file to avoid writing another 4GB file to disk and then adding it.
