1c05c65f6f Close tarsplit gzip writer when creating tar-split.json.gz files during layer migration
There is a missing call to Close on the gzip.Writer that is used to
compress newly created tar-split files during layer migration. This can
result in corrupt tar-split files that later cause docker push and
docker save to fail. The Close call is necessary to flush buffered data
to the stream.

Fixes: #20104

d04fa49a0d Refactor RWLayer to use referenced object instead of string
RWLayer will now have more operations and be protected through a referenced type rather than always looked up by string in the layer store.
Separates creation of RWLayer (write capture layer) from mounting of the layer.
This allows mount labels to be applied after creation and allowing RWLayer objects to have the same lifespan as a container without performance regressions from requiring mount.

500e77bad0 Add layer store
Layer store manages read-only and read-write layers on a union file system.
Read only layers are always referenced by content addresses.
Read-write layer identifiers are handled by the caller but upon registering
its difference, the committed read-only layer will be referenced by content
hash.
