The test case #303 added to visualize the QCOW2 metadata dumping. Suggested by Eric. The patch "Fix capitalization of header extension constant" has been pulled separately. 07: The class Qcow2BitmapTableEntry is now derived from the Qcow2Struct one. The constructors and methods of Qcow2BitmapTable and of Qcow2BitmapTableEntry were modified. 09: The python dict.update method was replaced with assignment operator. The interleaving dict 'entries' was removed from bitmap table dump. 10: The class Qcow2HeaderExtensionsDoc was removed. 11: New. The #303 was extended by dumping QCOW2 metadata in JSON format.
