[Qemu-devel] [PATCH v6 08/11] block: add support for --image-opts in block I/O tests

["Daniel P. Berrange" <berrange@redhat.com>]

Currently all block tests use the traditional syntax for images
just specifying a filename. To support the LUKS driver without
resorting to JSON, the tests need to be able to use the new
--image-opts argument to qemu-img and qemu-io.

This introduces a new env variable IMGOPTSSYNTAX. If this is
set to 'true', then qemu-img/qemu-io should use --image-opts.
