block: iterate_format with account of whitelisting
bdrv_iterate_format (which is currently only used for printing out the formats supported by the block layer) doesn't take format whitelisting into account. This creates a problem for tests: they enumerate supported formats to decide which tests to enable, but then discover that QEMU doesn't let them actually use some of those formats. To avoid that, exclude formats that are not whitelisted from enumeration, if whitelisting is in use. Since we have separate whitelists for r/w and r/o, take this a parameter to bdrv_iterate_format, and print two lists of supported formats (r/w and r/o) in main qemu.
