*: 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.

c37bd10f8c Update layer store to sync transaction files before committing
Fixes case where shutdown occurs before content is synced to disked
on layer creation. This case can leave the layer store in an bad
state and require manual recovery. This change ensures all files
are synced to disk before a layer is committed. Any shutdown that
occurs will only cause the layer to not show up but will allow it to
be repulled or recreated without error.

Added generic io logic to ioutils package to abstract it out of
the layer store package.

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.
