Clients today expect the repo to clean up if there are unused blobs, not to
manually delete things they think are unused. Let's do that, and use
umoci's code to do it since it's tested and works.
v2: also run GC on update as well as delete
v3: fix up error return paths needing two args

Fixes issue #67.
As per dist spec, DELETE of a image manifest can only be done with
digest as <reference> param. Previously, tags were being allowed as
well. This is not conformant to the spec.
dist-spec compliance tests are now becoming a part of dist-spec repo
itself - we want to be compliant
pkg/api/regex.go:
* revert uppercasing in repository names
pkg/api/routes.go:
* ListTags() should support the URL params 'n' and 'last'
for pagination
* s/uuid/session_id/g to use the dist-spec's naming
* Fix off-by-one error in GetBlobUpload()'s http response "Range" header
* DeleteManifest() success status code is 202
* Fix PatchBlobUpload() to account for "streamed" use case
where neither "Content-Length" nor "Content-Range" headers are set
pkg/storage/storage.go:
* Add a "streamed" version of PutBlobChunk() called PutBlobChunkStreamed()
pkg/compliance/v1_0_0/check.go:
* fix unit tests to account for changed response status codes
