Errors thrown by storage drivers don't have the name of the driver, causing user
confusion about whether the error is coming from Docker or from a storage driver.
This change adds the storage driver name to each error message.
This required changing ErrUnsupportedDriver to a type, leading to code changes
whenever ErrUnsupportedDriver is used. The tests check whether the driver name
appears in the error message.

This updates the vendored docker/distribution to the current master
branch.
Note the following changes:
- The manifest package was split into manifest/schema1. Most references
to the manifest package in the engine needed to be updated to use
schema1 instead.
- Validation functions in api/v2 were replaced by the
distribution/reference package. The engine code has been updated to
use the reference package for validation where necessary. A future PR
will change the engine to use the types defined in
distribution/reference more comprehensively.
- The reference package explicitly allows double _ characters in
repository names. registry_test.go was updated for this.
- TestPullFailsWithAlteredManifest was corrupting the manifest JSON, now
that the schema1 package unmarshals the correct payload. The test is
being changed to modify the JSON without affecting its length, which
allows the pull to succeed to the point where digest validation
happens.

This extends the specification for the Bearer token response to include
information pertaining to when an issued Bearer token will expire.
This also allows the client to accept `access_token` as an alias for `token`.

The proxy scheduler implemented its own timer state machine. It's
simpler and more efficient to leverage the Go runtime's timer heap by
using time.AfterFunc.
This commit adds a time.Timer to each scheduler entry, and starts and
stops those timers as necessary. Then the mainloop goroutine and its
associated logic are not needed.

To ensure that we only unmarshal the verified payload into the contained
manifest, we first copy the entire incoming buffer into Raw and then unmarshal
only the Payload portion of the incoming bytes. If the contents is later
verified, the caller can then be sure that the contents of the Manifest fields
can be trusted.

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.

Fixes https://github.com/docker/distribution/issues/1062
This relaxes the naming restrictions places on Docker images to permit
valid hostnames according to [RFC-2396](https://www.ietf.org/rfc/rfc2396.txt).
It deviates from the RFC in the following ways:
1) Allow underscores where we allow hyphens (hostnames don't allow
underscores, which we must for backwards compatibility).
2) Leave "top-level" name segments unrestricted (domains require an
alpha character to begin a top-level domain, e.g. "com").
3) DO NOT allow a trailing dot, as permitted by FQDNs.

Search terms shouldn't be restricted to only full valid repository
names. It should be perfectly valid to search using a part of a name,
even if it ends with a period, dash or underscore.

The "testing" package adds some flags in its init function, so utilities
that import distribution code may print a page of extra testing flags in
their help output.
This commit solves the issue by moving an import of "testing" in the
registry/storage/cache package to a new
registry/storage/cache/cachecheck package, which is only imported by
tests.

Add a daemon flag to control this behaviour. Add a warning message when pulling
an image from a v1 registry. The default order of pull is slightly altered
with this changset.
Previously it was:
https v2, https v1, http v2, http v1
now it is:
https v2, http v2, https v1, http v1
Prevent login to v1 registries by explicitly setting the version before ping to
prevent fallback to v1.
Add unit tests for v2 only mode. Create a mock server that can register
handlers for various endpoints. Assert no v1 endpoints are hit with legacy
registries disabled for the following commands: pull, push, build, run and
login. Assert the opposite when legacy registries are not disabled.

In the S3 storage driver there is currently an initial access permission check by listing the bucket. If this check fails, registry will panic and exit.
However, this check is broken in two ways. First of all it strips the final slash from the root directory path, meaning that any access permissions which limit access to a single directory will fail, because S3 treats the path as strict prefix match. Secondly it fails to strip any leading slash that might be present, unlike the other access places, which means that the path used is different as a leading slash is allowed and significant in a filename in S3.
Since there is also a periodic health check which correctly checks access permissions and shows the error more cleanly, the best solution seems to be to just remove this initial access check.
