Qu Wenruo d3cf350e21 btrfs-progs: introduce btrfs_rebuild_uuid_tree() for mkfs and btrfs-convert 
Currently mkfs uses its own create_uuid_tree(), but that function is
only handling FS_TREE.  This means for btrfs-convert we do not generate
the uuid tree, nor add the UUID of the image subvolume.  This can be a
problem if we're going to support multiple subvolumes during mkfs time.

To address this, introduce a new helper, btrfs_rebuild_uuid_tree():

- Create a new uuid tree if there is not one

- Remove all the existing items from uuid tree

- Iterate through all subvolumes
  * If the subvolume has no valid UUID, regenerate one
  * Add the uuid entry for the subvolume UUID
  * If the subvolume has received UUID, also add it to UUID tree

By this, this new helper can handle all the uuid tree generation needs for:

- Current mkfs
  Only one uuid entry for FS_TREE

- Current btrfs-convert
  Only FS_TREE and the image subvolume

- Future multi-subvolume mkfs
  As we do the scan for all subvolumes.

- Future "btrfs rescue rebuild-uuid-tree"
