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.
