fsck.ubifs: Handle orphan nodes
This is the 3/18 step of fsck. Handle orphan nodes, update TNC & LPT.
There could be following steps and possible errors:
Step 1. scan orphan LEB, get all orphan nodes
a. corrupted scanning data in orphan area: danger mode and normal mode
with 'yes' answer will drop orphan LEB, other modes will exit.
Step 2. parse orphan node, find the original inode for each inum
a. corrupted node searched from TNC: skip node for danger mode and
normal mode with 'yes' answer, other modes will exit.
b. corrupted index node read from TNC: danger mode with rebuild_fs and
normal mode with 'yes' answer will turn to rebuild filesystem, other
modes will exit.
Step 4. remove inode for each inum, update TNC & LPT
a. corrupted index node read from TNC: danger mode with rebuild_fs and
normal mode with 'yes' answer will turn to rebuild filesystem, other
modes will exit.
b. corrupted lpt: Set %FR_LPT_CORRUPTED for lpt status. Ignore the
error.
c. incorrect lpt: Set %FR_LPT_INCORRECT for lpt status. Ignore the
error.
d. If lpt status is not empty, skip updating lpt.
