A zlib regression test has been added to verify the correct behavior of z_compress_level() and z_uncompress. The test case simply takes a 128k buffer, it compresses the buffer, it them uncompresses the buffer, and finally it compares the buffers after the transform. If the buffers match then everything is fine and no data was lost. It performs this test for all 9 zlib compression levels.
