This patch adds the support for reporting the image end offset (in
bytes). This is particularly useful after a conversion (or a rebase)
where the destination is a block device in order to find the first
unused byte at the end of the image.

To do this, we start a qemu-nbd process at _make_test_img and kill
it in _cleanup_test_img. $TEST_IMG is changed to point at the TCP
server. We also remove the checks for existence of binaries from
common.config - they're duplicated in common, and we can make the
qemu-nbd check conditional on $IMGPROTO being "nbd" if we do it there.

qemu-iotests already filters out image creation options that may be
present or not in order to get the same output in both cases. However,
often it only considers the default value of the option. Cover all valid
values instead so that ./check -o name=value can be used successfull for
all of them.

Hide the default lazy_refcounts=off output from qemu-img like we do with
other image creation options.  This ensures that existing golden outputs
continue to pass despite the new option that has been added.

Note that this patch applies before the one that actually introduces the
lazy_refcounts=on|off option.  This ensures git-bisect(1) continues to
work.

We added image fragmentation statistics functions to qemu-img several days
ago, those patches will cause "./check -qed" failed. This patch will ignore
fragmentation statistics information of qed format, and then "./check -qed"
will work.

This adds an -o option to qemu-iotests, which is an option string that
is passed through to qemu-img create -o... This allows testing different
subformat with a command like './check -qcow2 -o compat=0.10'.

For qcow2, if no compat option is specified, compat=1.1 is the new
default.

Some image formats do have a cluster size, others don't, but there are
tests that work with both sets of images and currently we get failures
because the qemu-img create output doesn't mention the cluster size for
some formats.

qemu-img requires first options, then file name, then size.

GNU getopt also allows options at the end, but POSIX getopt
doesn't. Try "export POSIXLY_CORRECT=y" to get the POSIX
behaviour with GNU getopt, too.

Until recently, qemu-img create displayed cluster_size=0 for the default
cluster size. It is changed to display the real cluster size now, which results
in the cluster size not being filtered out any more.

If the cluster size is specified explicitly in CLUSTER_SIZE, keep the output,
and if using the default, filter it out. This mostly restores the old behaviour
of the test cases; test 015 must be fixed to use CLUSTER_SIZE instead of using
extra_img_options for it.

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).
