It is possible to enable only a subset of the block drivers with the "--block-drv-rw-whitelist" option of the "configure" script. All other drivers are marked as unusable (or only included as read-only with the "--block-drv-ro-whitelist" option). If an iotest is now using such a disabled block driver, it is failing - which is bad, since at least the tests in the "auto" group should be able to deal with this situation. Thus let's introduce a "_require_drivers" function that can be used by the shell tests to check for the availability of certain drivers first, and marks the test as "not run" if one of the drivers is missing. This patch mainly targets the test in the "auto" group which should never fail in such a case, but also improves some of the other tests along the way. Note that we also assume that the "qcow2" and "file" drivers are always available - otherwise it does not make sense to run "make check-block" at all (which only tests with qcow2 by default).
