This trimmed version includes the extent support for label operations
which significantly speeds up common label operations like
'init-labels'. It also fixes up some surprising results from
'create-namespace' where it would fail even though available capacity is
present. Lastly it suppresses a new warning found in Fedora Rawhide
builds that has moved to gcc 9.1.1.
