f7f3d34210 Move CreateRWLayer() parameters in a struct
Move some of the optional parameters of CreateRWLayer() in a struct
called CreateRWLayerOpts. This will make it easy to add more options
arguments without having to change signature of CreateRWLayer().

50a498ea1c Verify layer tarstream
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.

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.
