David Sterba 7541b53b34 btrfs-progs: dump-tree: add untyped item ptr helper and use it 
There's lots of code that passes btrfs_item_ptr. Add a helper to extract
the ptr at the beginning, ignoring the type. The print functions take
the correct type, but we ignore it in the conversion macros as it does
not provide the type checking anyway.

If the typed variable is used more than once, it's kept in place.

David Sterba e244550b42 btrfs-progs: introduce key type for persistent permanent items 
The number of distinct key types is not that big that we could waste one
for something new we want to store in the tree.

Similar to the temporary items, we'll introduce a new name for an
existing key value and use the objectid for further extension.  The
victim is the BTRFS_DEV_STATS_KEY (248).

The device stats are an example of a permanent item.

The number of distinct key types is not that big that we could waste one
for something new we want to store in the tree. We'll introduce a new
name for an existing key value and use the objectid for further
extension.  The victim is the BTRFS_BALANCE_ITEM_KEY (248).

The nature of the balance status item is a good example of the temporary
item. It exists from beginning of the balance, keeps the status until it
finishes.

David Sterba d4aa2bc07e btrfs-progs: subvol show: print more details about toplevel subvolume 
The toplevel subvolume is special and the other listing code leaves it
out so we have to add several special cases to handle it. There's no
backreference so the path is built artificially. New helper
btrfs_get_toplevel_subvol is a reduced version of btrfs_get_subvol.

There's some information usually missing for the toplevel subvolume, eg.
the uuid or creation info. This has to be fixed on the mkfs side, the
other subvolumes are created by kernel.

Example:
/mnt
        Name:                   <FS_TREE>
        UUID:                   -
        Parent UUID:            -
        Received UUID:          -
        Creation time:          -
        Subvolume ID:           5
        Generation:             233
        Gen at creation:        0
        Parent ID:              0
        Top level ID:           0
        Flags:                  -
        Snapshot(s):
