fsck.ubifs: Traverse TNC and construct files
This is the 6/18 step of fsck. Traverse TNC and construct files. There
could be following steps and possible errors:
Step 1. Traverse TNC, check whether the leaf node is valid, remove invalid
nodes, construct file for valid node and insert file into file tree.
a. corrupted node searched from TNC: remove corresponding TNC branch 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.
