Recent patches updated stale qgroup handling, using 'unlinked' and
'dropped' where we otherwise use 'deleted' and 'cleaned'.

Currently `btrfs qgroup show` command shows any 0 level qgroup without a
root backref as `<stale>`, which is not correct.
There are several more cases:
- Under deletion
The subvolume is not yet full dropped, but unlinked.
In that case we would not have a root backref item, but the qgroup is
not stale.
- Squota space holder
This is for squota mode, that a fully dropped subvolume still have
extents accounting on the already-gone subvolume.
In this case it's not stale either, and future accounting relies on
it.
This patch would add above special cases, and add an extra `SPECIAL
PATHS` section to explain all the cases, including `<stale>`.

A stale qgroup is level 0 and without a corresponding subvolume. There's
no convenient command for removing them and kernel does not remove them
automatically. Add a command so users don't have to parse and script the
output and/or delete them manually.
