qemu-iotests: Use zero-based offsets for IO patterns

The io_pattern style functions have the following loop:

for i in `seq 1 $count`; do
      echo ... $(( start + i * step )) ...
  done

Offsets are 1-based so start=1024, step=512, count=4 yields:
1536, 2048, 2560, 3072...

qemu-iotests: explicitly use bash interpreter

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.

qemu-iotests: replace FSF postal addresses with www.gnu.org links

Blue Swirl notices that we were using the old FSF post address in the

functions. Unfortunately, this contains a space character...

qemu-iotests: align test requests according to cluster size

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...

qemu-iotests: test larger clusters sizes on qcow2

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)....

qemu-iotests: make a few more tests generic

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