Some block devices may not have a filename in their BDS; and for some, there may not even be a normal filename at all. To work around this, add a function which tries to construct a valid filename for the BDS.filename field. If a filename exists or a block driver is able to reconstruct a valid filename (which is placed in BDS.exact_filename), this can directly be used. If no filename can be constructed, we can still construct an options QDict which is then converted to a JSON object and prefixed with the "json:" pseudo protocol prefix. The QDict is placed in BDS.full_open_options. For most block drivers, this process can be done automatically; those that need special handling may define a .bdrv_refresh_filename() method to fill BDS.exact_filename and BDS.full_open_options themselves.
