Split apart repository reference into domain and path
Allows having other parsers which are capable of unambiguously keeping domain and path separated in a Reference type.

bc1e7aa603 digest: Preserve tag and digest in With* functions
When WithDigest is called on a reference that has a tag, it should
preserve the tag.

When WithTag is called on a reference that has digest, it should
preserve the digest.

744ae974a5
Improve "invalid reference" error message
Use the same error message as is used in
docker/reference/reference.go to provide
slightly more information about the error.

This change tests if the reference passes
after lowercasing its characters, to determine
if the reference was invalid due to
it containing uppercase characters.

073bd89262 Check length of input in WithName
There is a constraint on the length of the name in a reference, so
WithName should be checking this instead of potentially creating a
reference that doesn't comply with the rules.

This was using a different regexp from the intended one. This meant that
tags with uppercase characters were not accepted.

16eea0cc47 Usability improvements for reference package
Various improvements motivated by early real-world use in engine code
under development:

- Make `WithDigest` return `Canonical`, since the return value always
  has a name and a digest.

- Introduce a `NamedTagged` type, which can be used for strongly typing
  cases where something must have a name and a tag.

- Rename `ParseNamed` to `WithName`, and create a
  `ParseNamed` that accepts tags and digests (returning a `Named` type).
  The new `ParseNamed` makes code using the reference package much less
  verbose, since typical use cases require a name, and this is an
  additional type assertion and error case after every `Parse` call.

b07d759241 Add WithTag and WithDigest combinator functions
These functions allow a Named type to be combined with a tag or a
digest. WithTag will replace the ImageReference function in
github.com/docker/docker/utils as the Docker Engine transitions to the
reference package.

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.
