7faf96e30a btrfs-progs: also check filesystem type in test_issubvolume 
A subvolume is a directory with inode number 256 on a btrfs filesytem.
Add the missing check to test_issubvolume for completeness, otherwise we
always do that in btrfs_open_dir.

2078848983 btrfs-progs: debug-tree: teach -t option about the chunk and root trees 
A user on IRC wanted to dump the chunk tree using the -t option. As the
-t option enumerates only trees pointed by the tree_root, the chunk tree
is skipped. Similar for th tree of tree roots.

e4797df6a9 btrfs-progs: check the free space tree in btrfsck 
This reuses the existing code for checking the free space cache, we just
need to load the free space tree. While we do that, we check a couple of
invariants on the free space tree itself. This requires pulling in some
code from the kernel to exclude the super stripes.

d8c537e71f btrfs-progs: add basic awareness of the free space tree 
To start, let's tell btrfs-progs to read the free space root and how to
print the on-disk format of the free space tree. However, we're not
adding the FREE_SPACE_TREE read-only compat bit to the set of supported
bits because progs doesn't know how to keep the free space tree
consistent.
