Some tests do not work well with certain refcount widths (i.e. you
cannot create internal snapshots with refcount_bits=1), so make those
widths unsupported.
Furthermore, add another filter to _filter_img_create in common.filter
which filters out the refcount_bits value.
This is necessary for test 079, which does actually work with any
refcount width, but invoking qemu-img directly leads to the
refcount_bits value being visible in the output; use _make_test_img
instead which will filter it out.

all these tests do anything of the following and thus fail with any
protocol other than file:
- the tests use rm, cp or mv shell commands which only work on file
- the tests use qcow2.py
- the images construct new filenames (e.g. backing file names) and
the logic is broken for anything else than file

This replaces _unsupported_qemu_io_options and check for support of
current cache mode, and allow to provide a default if user didn't
specify.

A lot of image filename and paths are used unquoted. Quote these to
make sure that directories / filenames with spaces are not problematic.

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.

qemu-iotests supports the -nocache option which makes the tests run with
cache=none. For blkdebug tests with qcow2 this means that we may see
test results that differ from cache=writethrough. This patch makes the
diff a bit smaller and therefore easier to review.
