Fix issue with restoring the tag store and setting static configuration
from the daemon. i.e. the field on the TagStore struct must be made
internal or the json.Unmarshal in restore will overwrite the insecure
registries to be an empty struct.

We do this to prevent leakage of information, we don't want people
to be able to probe for existing content.
According to RFC 2616, "This status code (404) is commonly used when the server does not
wish to reveal exactly why the request has been refused, or when no other response i
is applicable."
https://www.ietf.org/rfc/rfc2616.txt
10.4.4 403 Forbidden
The server understood the request, but is refusing to fulfill it.
Authorization will not help and the request SHOULD NOT be repeated.
If the request method was not HEAD and the server wishes to make
public why the request has not been fulfilled, it SHOULD describe the
reason for the refusal in the entity. If the server does not wish to
make this information available to the client, the status code 404
(Not Found) can be used instead.
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No
indication is given of whether the condition is temporary or
permanent. The 410 (Gone) status code SHOULD be used if the server
knows, through some internally configurable mechanism, that an old
resource is permanently unavailable and has no forwarding address.
This status code is commonly used when the server does not wish to
reveal exactly why the request has been refused, or when no other
response is applicable.
When docker is running through its certificates, it should continue
trying with a new certificate even if it gets back a 404 error code.

Add support for pulling signed images from a version 2 registry.
Only official images within the library namespace will be pull from the
new registry and check the build signature.

This lets you specify custom client TLS certificates and CA root for a
specific registry hostname. Docker will then verify the registry
against the CA and present the client cert when talking to that
registry. This allows the registry to verify that the client has a
proper key, indicating that the client is allowed to access the
images.
A custom cert is configured by creating a directory in
/etc/docker/certs.d with the same name as the registry hostname. Inside
this directory all *.crt files are added as CA Roots (if none exists,
the system default is used) and pair of files <filename>.key and
<filename>.cert indicate a custom certificate to present to the registry.
If there are multiple certificates each one will be tried in
alphabetical order, proceeding to the next if we get a 403 of 5xx
response.
So, an example setup would be:
/etc/docker/certs.d/
└── localhost
├── client.cert
├── client.key
└── localhost.crt
A simple way to test this setup is to use an apache server to host a
registry. Just copy a registry tree into the apache root, here is an
example one containing the busybox image:
http://people.gnome.org/~alexl/v1.tar.gz
Then add this conf file as /etc/httpd/conf.d/registry.conf:
# This must be in the root context, otherwise it causes a re-negotiation
# which is not supported by the tls implementation in go
SSLVerifyClient optional_no_ca
<Location /v1>
Action cert-protected /cgi-bin/cert.cgi
SetHandler cert-protected
Header set x-docker-registry-version "0.6.2"
SetEnvIf Host (.*) custom_host=$1
Header set X-Docker-Endpoints "%{custom_host}e"
</Location>
And this as /var/www/cgi-bin/cert.cgi
#!/bin/bash
if [ "$HTTPS" != "on" ]; then
echo "Status: 403 Not using SSL"
echo "x-docker-registry-version: 0.6.2"
echo
exit 0
fi
if [ "$SSL_CLIENT_VERIFY" == "NONE" ]; then
echo "Status: 403 Client certificate invalid"
echo "x-docker-registry-version: 0.6.2"
echo
exit 0
fi
echo "Content-length: $(stat --printf='%s' $PATH_TRANSLATED)"
echo "x-docker-registry-version: 0.6.2"
echo "X-Docker-Endpoints: $SERVER_NAME"
echo "X-Docker-Size: 0"
echo
cat $PATH_TRANSLATED
This will return 403 for all accessed to /v1 unless *any* client cert
is presented. Obviously a real implementation would verify more details
about the certificate.
Example client certs can be generated with:
openssl genrsa -out client.key 1024
openssl req -new -x509 -text -key client.key -out client.cert

This is the first step towards separating the registry subsystem from
the deprecated `Server` object.
* New service `github.com/dotcloud/docker/registry/Service`
* The service is installed by default in `builtins`
* The service only exposes `auth` for now...
* ...Soon to be followed by `pull`, `push` and `search`.

roll version and standalone information into the _ping. And to support
Headers they are checked after the JSON is loaded (if there is anything
to load). To stay backwards compatible, if the _ping contents are not
able to unmarshal to RegistryInfo, do not stop, but continue with the
same behavior.

For a pull-only, static registry, there only a couple of headers that
need to be optional (that are presently required.

* X-Docker-Size
* X-Docker-Endpoints
