Pass the manifestURL directly into the schema2 manifest handler instead of
accessing through the repository as it has since the reference is now an
interface.

Until we have some experience hosting foreign layer manifests, the Hub
operators wish to limit foreign layers on Hub. To that end, this change
adds registry configuration options to restrict the URLs that may appear
in pushed manifests.

Adds a constant leeway (60 seconds) to the nbf and exp claim check to
account for clock skew between the registry servers and the
authentication server that generated the JWT.
The leeway of 60 seconds is a bit arbitrary but based on the RFC
recommendation and hub.docker.com logs/metrics where we don't see
drifts of more than a second on our servers running ntpd.
I didn't attempt to make the leeway configurable as it would add extra
complexity to the PR and I am not sure how Distribution prefer to
handle runtime flags like that.
Also, I am simplifying the exp and nbf check for readability as the
previous `NOT (A AND B)` with cmp operators was not very friendly.

This fixes errors other than io.EOF from being dropped when a storage driver
lists repositories. For example, filesystem driver may point to a missing
directory and errors, which then gets subsequently dropped.

Allows using v2 for v1 endpoints.
The primary use case being for search which does not have a v2 specification.
Added a user scope for allowing v2 search

This is similar to waitForSegmentsToShowUp which is called during
Close/Commit. Intuitively, you wouldn't expect missing segments to be a
problem during read operations, since the previous Close/Commit
confirmed that all segments are there.
But due to the distributed nature of Swift, the read request could be
hitting a different storage node of the Swift cluster, where the
segments are still missing.
Load tests on my team's staging Swift cluster have shown this to occur
about once every 100-200 layer uploads when the Swift proxies are under
high load. The retry logic, borrowed from waitForSegmentsToShowUp, fixes
this temporary inconsistency.

In Go's header parsing, the same header multiple times results in multiple entries in the `r.Header[...]` slice, but Go does no further parsing beyond that (and in https://golang.org/cl/4528086 it was determined that until/unless the stdlib itself needs it, Go will not do so).
The consequence here for parsing of `Accept:` headers is that we support the way Go outputs headers, but not all language HTTP libraries have a facility to output multiple headers instead of a single list header.
This change ensures that the following (valid) header blocks all parse to the same result for the purposes of what is being tested here:
```
Accept: a/b
Accept: b/c
Accept: d/e
```
```
Accept: a/b; q=0.5, b/c
Accept: d/e
```
```
Accept: a/b; q=0.1, b/c; q=0.2, d/e; q=0.8
```
