When calling stats on stopped container's print out zeros for all of the
values to populate the initial table. This signals to the user that the
operations completed and will not block.

To address the possibility of confusing registry name components with
repository paths, path components that abut user provided repository names are
escaped with a prefixed underscore. This works because repository name
components are no allowed to start with underscores. The requirements on
backend driver path names have been relaxed greatly to support this use case.

This changeset provides simple tls support for a registry instance. Simply
providing a cert and key file are enough to get a tls registry running. If the
certs are trusted by the client, tls can be used throughout the push and pull
process.
If more complex TLS options are required, it is recommend that a proxy be used.
Contributions will be accepted to add more features, if necessary.

* Result of regexp.FindStringSubmatch must be checked to be not nil.
Otherwise it leads to `index out of range`.
* Range header regexp is compiled only once to speedup (5x) the header parsing.

Several API tests were added to ensure correct acceptance of zero-size and
empty tar files. This led to several changes in the storage backend around the
guarantees of remote file reading, which backs the layer and layer upload type.
In support of these changes, zero-length and empty checks have been added to
the digest package. These provide a sanity check against upstream tarsum
changes. The fileReader has been modified to be more robust when reading and
seeking on zero-length or non-existent files. The file no longer needs to exist
for the reader to be created. Seeks can now move beyond the end of the file,
causing reads to issue an io.EOF. This eliminates errors during certain race
conditions for reading files which should be detected by stat calls. As a part
of this, a few error types were factored out and the read buffer size was
increased to something more reasonable.

It's ambiguous to say that `ENV` is _functionally equivalent to prefixing the command with `<key>=<value>`_. `ENV` sets the environment for all future commands, but `RUN` can take chained commands like `RUN foo=bar bash -c 'echo $foo' && bash -c 'echo $foo $bar'`. Users with a solid understanding of `exec` may grok this without confusion, but less experienced users may need this distinction.

Handles an issue where mux.Route does not set the desired scheme
when building a url and always uses `http`.
Now uses X-Forwarded-Proto when creating a URLBuilder from a request.
