fsck.ubifs: Add fsck support
Add basic process code for fsck.ubifs. There are following modes for fsck: 1. normal mode: Check the filesystem, ask user whether or not to fix the problem as long as inconsistent data is found during fs checking. 2. safe mode: Check and safely repair the filesystem, if there are any data dropping operations needed by fixing, fsck will fail. 3. danger mode: Answer 'yes' to all questions. There two sub modes: a) Check and repair the filesystem according to TNC, data dropping will be reported. If TNC/master/log is corrupted, fsck will fail. b) Check and forcedly repair the filesystem according to TNC, turns to rebuild filesystem if TNC/master/log is corrupted. Always make fsck succeed. 4. check mode: Make no changes to the filesystem, only check the filesystem. 5. rebuild mode: Scan entire UBI volume to find all nodes, and rebuild filesystem, always make fsck success.
