The old test didn't consider cases in which the COW files contains some
unallocated clusters and after them allocated ones again.

This patch adds an image resize grow test to ensure that existing data
is not lost during grow and new space is zeroed.

The tests use bash language features like 'let', which aren't supported
by /bin/sh on systems that use a conservative shell like dash. This
patch changes the interpreter to /bin/bash.

This patch adds test case 023 which tests some more cluster sizes. For
anythinger larger than 4k clusters we can't use requests that are l2_size or
more (128k for 1k clusters, 2 MB for 4k clusters, 512 MB for 64k clusters).
Therefore one of the common.pattern cases is changed and needs new expected
results for some old test cases.

Change the io_test and io_test2 functions to take the cluster size of the image
and the number of test requests to issue. Tests are changed to specify a
cluster size (usually 4k), but expected test results stay the same for now
(apart from qemu-img printing the cluster size now).
Based on a patch written by Christoph Hellwig.

We need to be able to pass "write -b" as an operation to the pattern testing
functions. Unfortunately, this contains a space character...

Blue Swirl notices that we were using the old FSF post address in the
license boilerplates. Replace both the old and new address with links
to the gnu.org licenses homepage as suggested by Ben Pfaff.

The write pattern value 0axb is invalid and evaluates to 0,
so the read check (which uses a correct value of 0xab) will fail.
This failure will only be detected with a separate patch for
qemu-io. Without it, qemu-io cannot interpret hex values
and always uses a pattern value of 0.

Pretend that a non-implemented check is always successful and thus allow
various tests that were qcow2-specific before to be generic.
