btrfs-progs: tests: test for FST corruption detection/repair

The patchset aims to support check and repair errors about
inode_extref in lowmem mode. 
patch[1-2] let btrfs_unlink() detect inode_extref.
patch[3] fixes a minor bug in check_dir_item due to my careless
	 long ago.
patch[4] fixes a bug about inconsistent path in check_fs_roots()
	 under repair.
patch[5] fixes a corner case about traversal of inode items.
patch[6] enable inode_extref repair support and remove unnecessary
	 checks.
patch[7] add a test image, it can verify above patches except
	 patch[3].

Changelog:
v3:
   Handle fatal errors instead of BUG_ON() in patch[4, 6].
   	  Thanks, Qu Wenruo and Nikolay Borisov.
   Change comments and move declarations in patch[3]. Pointed by Qu Wenruo.
   Handle corner case mentioned in patch[5] in walk_up_tree() not
   	  process_one_leaf().
   Test image are only with inode_extref now.  Suggested by Qu Wenruo.
v2:
   Resend with patches in right order.
