6bd5b8c24e Update regexp to support repeated dash and double underscore
In order to support valid hostnames as name components, supporting repeated dash was added.
Additionally double underscore is now allowed as a separator to loosen the restriction for previously supported names.

bcda04d6cd Add field type for serialization
Since reference itself may be represented by multiple types which implement the reference inteface, serialization can lead to ambiguous type which cannot be deserialized.
Field wraps the reference object to ensure that the correct type is always deserialized, requiring an extra unwrap of the reference after deserialization.

f8c09b6a7d Add a new reference package abstracting repositories, tags and digests
There seems to be a need for a type that represents a way of pointing
to an image, irrespective of the implementation.

This patch defines a Reference interface and provides 3 implementations:
- TagReference: when only a tag is provided
- DigestReference: when a digest (according to the digest package) is
  provided, can include optional tag as well

Validation of references are purely syntactic.

There is also a strong type for tags, analogous to digests, as well
as a strong type for Repository from which clients can access the
hostname alone, or the repository name without the hostname, or both
together via the String() method.

For Repository, the files names.go and names_test.go were moved from
the v2 package.
