f9a3f028b5 Fix content type for schema1 signed manifests
The Payload function for schema1 currently returns a signed manifest,
but indicates the content type is that of a manifest that isn't signed.

Note that this breaks compatibility with Registry 2.3 alpha 1 and
Docker 1.10-rc1, because they use the incorrect content type.

3da0ee00d8 Do not require "charset=utf-8" for a schema1 with content type application/json
For compatibility with other registries that don't use this exact
variant of the Content-Type header, we need to be more flexible about
what we accept. Any form of "application/json" should be allowed. The
charset should not be included in the comparison.

Richard Scothern
8efb9ca329 Implementation of the Manifest Service API refactor.
Add a generic Manifest interface to represent manifests in the registry and
remove references to schema specific manifests.

Add a ManifestBuilder to construct Manifest objects. Concrete manifest builders
will exist for each manifest type and implementations will contain manifest
specific data used to build a manifest.

Remove Signatures() from Repository interface.

Signatures are relevant only to schema1 manifests.  Move access to the signature
store inside the schema1 manifestStore.  Add some API tests to verify
signature roundtripping.

schema1
-------

Change the way data is stored in schema1.Manifest to enable Payload() to be used
to return complete Manifest JSON from the HTTP handler without knowledge of the
schema1 protocol.

tags
----

Move tag functionality to a seperate TagService and update ManifestService
to use the new interfaces.  Implement a driver based tagService to be backward
compatible with the current tag service.

Add a proxyTagService to enable the registry to get a digest for remote manifests
from a tag.

manifest store
--------------

Remove revision store and move all signing functionality into the signed manifeststore.

manifest registration
---------------------

Add a mechanism to register manifest media types and to allow different manifest
types to be Unmarshalled correctly.

client
------

Add ManifestServiceOptions to client functions to allow tags to be passed into Put and
Get for building correct registry URLs.  Change functional arguments to be an interface type
to allow passing data without mutating shared state.

58232e50cf Simplify digest.FromBytes calling convention
The current implementation of digest.FromBytes returns an error. This
error can never be non-nil, but its presence in the function signature
means each call site needs error handling code for an error that is
always nil.

I verified that none of the hash.Hash implementations in the standard
library can return an error on Write. Nor can any of the hash.Hash
implementations vendored in distribution.

This commit changes digest.FromBytes not to return an error. If Write
returns an error, it will panic, but as discussed above, this should
never happen.

This commit also avoids using a bytes.Reader to feed data into the hash
function in FromBytes. This makes the hypothetical case that would panic
a bit more explicit, and should also be more performant.

Issue #1186 describes a condition where a null tags response is returned when
using the s3 driver. The issue seems to be related to a missing
PathNotFoundError in s3. This change adds a test for that to get an idea of the
lack of compliance across storage drivers. If the failures are manageable,
we'll add this test condition and fix the s3 driver.

This change removes the sort() from the Repositories() function since
we're now guaranteed to have a lexigraphically sorted walk.

bf2cc0a9d6 Avoid stat round-trips when fetching a blob
Without this commit, three round-trips are required to fetch a blob with
a progress bar. The first is a call to Stat (HEAD request), to determine
the size. Then Open is called, which also calls Stat, and finally
performs a GET request.

Only the GET request is actually needed. The size of the blob can be
sniffed from Content-Length in the GET response.

This commit changes HTTPReadSeeker to automatically detect the size from
Content-Length instead of requiring it to be passed in. The Stat call is
removed from Open because it is no longer necessary.

HTTPReadSeeker now takes an additional errorHandler callback argument which
translates an unsuccessful HTTP response into an appropriate API-level
error. Using a callback for this makes it possible to avoid leaking the
repsonse body to Read's caller, which would make lifecycle management
problematic.

Fixes #1223
