c19ac510a7 btrfs-progs: move repair.[ch] to common/ 
Move the file to common as it's used by several parts, while still
keeping the name 'repair' although the only thing it does is adding a
corrupted extent.

0595309541 btrfs-progs: fix null pointer deref in balance_level 
In case the right buffer is emptied it's first set to NULL and
subsequently it's dereferenced to get its size to pass to root_sub_used.
This naturally leads to a NULL pointer dereference. The correct thing to
do is to pass the stashed right->len in "blocksize".

be6710f89d btrfs-progs: print bytenr of child eb if mismatched level found in read_node_slot 
If btrfs check reported like

  ERROR: child eb corrupted: parent bytenr=178081 item=246 parent level=1 child level=2

It's hard to find which eb is corrupted without bytenr in dump tree
information:

  node 178081 level 1 items 424 free 69 generation 44495 owner EXTENT_TREE
  fs uuid 7d9dbe1b-dea6-4141-807b-026325123ad8

	  key (16857755648 EXTENT_ITEM 4096) block 177857544192 gen 44416
  ...

For easier lookup, print bytenr of child eb if its level is not equal
to parent's level - 1 in read_node_slot().
