b4e9b50765 layer/CreateRWLayerByGraphID: remove
This is an additon to commit 1fea38856a ("Remove v1.10 migrator")
aka PR #38265. Since that one, CreateRWLayerByGraphID() is not
used anywhere, so let's drop it.

05250a4f00 layer: optimize layerStore mountL
Goroutine stack analisys shown some lock contention
while doing massively (100 instances of `docker rm`)
parallel image removal, with many goroutines waiting
for the mountL mutex. Optimize it.

With this commit, the above operation is about 3x
faster, with no noticeable change to container
creation times (tested on aufs and overlay2).

kolyshkin@:
- squashed commits
- added description
- protected CreateRWLayer against name collisions by
temporary assiging nil to ls.mounts[name], and treating
nil as "non-existent" in all the other functions.

ce8e529e18 LCOW: Re-coalesce stores
Signed-off-by: John Howard <jhoward@microsoft.com>

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.

*: use opencontainers/go-digest package
The `digest` data type, used throughout docker for image verification
and identity, has been broken out into `opencontainers/go-digest`. This
PR updates the dependencies and moves uses over to the new type.

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.
