[PATCH v2 0/6] btrfs-progs: print-tree: Minor enhancement along with --bfs/--dfs options

[Qu Wenruo <wqu@suse.com>]

This patchset can be fetched from github:
https://github.com/adam900710/btrfs-progs/tree/dump_tree_enhance

The main point of this patchset is to allow "btrfs ins dump-tree" to
print tree blocks in breadth-first order when level is higher than 2.

The 1st patch is just a minor cleanup, to remove some unused and
meaningless output.

The 2nd patch does a root<->fs_info cleanup, provides the basis for
later btrfs_next_sibling_tree_block().

The 3rd patch implements a new function, btrfs_next_sibling_tree_block()
to find next sibling tree block, other than leaf.

The 4th patch implements BFS as bfs_print_children().

The BFS search itself is implemented using path along with
 path::lowest_level and btrfs_next_sibling_tree_block() to iterate all
sibling tree blocks in a level.

The 5th patch adds --bfs/--dfs options for dump-tree.

The final patch changes @follow type from int to bool.

Changelog:
v2:
  Make bfs/dfs selectable by adding --bfs and --dfs options.
  Still keep dfs as default (although I really don't see any
  compatibility problem)
  Add a new patch to change @follow type.
