The re-coalesces the daemon stores which were split as part of the
original LCOW implementation.
This is part of the work discussed in https://github.com/moby/moby/issues/34617,
in particular see the document linked to in that issue.
This adds verification for getting layer data out
of layerstore. These failures should only be possible
if layer metadata files have been manually changed
of if something is wrong with tar-split algorithm.
Failing early makes sure we don’t upload invalid data
to the registries where it would fail after someone
tries to pull it.
