Just a minor cleanup to make the parameter easier to read.

Originally print-tree uses depth first search to print trees.
This works fine until we reach 3 level trees (root node level is 2).
For tall trees whose root level is 2 or higher, DFS will mix nodes and
leaves like the following example:
Level 2 A
/ \
Level 1 B C
/ | | \
Level 0 D E F G
DFS will cause the following output sequence:
A B D E C F G
Which in term of node/leave is:
N N L L N L L
Such mixed node/leave result is sometimes hard for human to read.
This patch will introduce 2 new options, --bfs and --dfs.
--dfs: keeps the original output sequence, and to keep things
compatible it's the default behavior.
--bfs: uses breadth-first search, and will cause better output
sequence like:
A B C D E F G
Which in term of node/leave is:
N N N L L L L
Much better sorted and may become default in the future.

Just like kernel cleanup made by David, btrfs_print_leaf() and
btrfs_print_tree() doesn't need btrfs_root parameter at all.
With previous patches as preparation, now we can remove the btrfs_root
parameter.

This function is quite useful for a lot of error report.
Enhance it to support custom output other than stdout.
And export it for later btrfsck enhancement.

There are missing ifdefs or defines with very generic names.

This patch adds functionality (in qgroup-verify.c) to compute bytecounts in
subvolume quota groups. The original groups are read in and stored in memory
so that after we compute our own bytecounts, we can compare them with those
on disk. A print function is provided to do this comparison and show the
results on the console.
A 'qgroup check' pass is added to btrfsck. If any subvolume quota groups
differ from what we compute, the differences for them are printed. We also
provide an option '--qgroup-report' which will run only the quota check code
and print a report on all quota groups. Other than making it possible to
verify that our qgroup changes work correctly, this mode can also be used in
xfstests for automated checking after qgroup tests.
This patch does not address the following:
- compressed counts are identical to non compressed, because kernel doesn't
make the distinction yet. Adding the code to verify compressed counts
shouldn't be hard at all though once kernel can do this.
- It is only concerned with subvolume quota groups (like most of
btrfs-progs).

Add sys chunk array and backup roots info if the new option '-f'
if specified.
This may be useful for debugging sys_chunk related issues.

output objectid in btrfs_disk_key with human readable strings.
Other updates are included for more readable output.
