Add simple test for zip/unzip/gzwrite commands. The test works as follows. First, create three buffers with a bit of space between each of them, fill them with random data, then compress data in buffer 1 into buffer 2, decompress data in buffer 2 either directly into buffer 3 or into MMC 1 and then read them back into buffer 3, and finally compare buffer 1 and buffer 3, they have to be identical. The buffers are filled with random data to detect out of bounds writes. Test for various sizes, both small and large and unaligned. The test uses ut_assert_skip_to_line() to skip over gzwrite progress bar. Since the progress bar updates fill up the console record buffer, increase the size of it to compensate.
