Previously, the specificiation incorrectly bound the fates of `urls` and
foreign layers. These are complementary but unrelated features, in that
the `urls` field may be populated for layers that aren't foreign. The
type of the layer only dictates the push behavior of the layer, rather
than involving where it came from.
For example, one may pull a foreign layer from a registry, but they may
not push it back to another registry. Conversely, a layer that has no
restrictions on push/pull behavior may be fetched via `urls` entries.

* tag service: properly handle error responses on HEAD requests by
re-issuing requests as GET for proper error details.
Fixes#1911.
Signed-off-by: dmitri <deemok@gmail.com>
* Simplify handling of failing HEAD requests in TagService and
make a GET request for cases:
- if the server does not handle HEAD
- if the response was an error to get error details

* Add a missing http.Response.Body.Close call for the GET request.

This change to the S3 Move method uses S3's multipart upload API to copy
objects whose size exceeds a threshold. Parts are copied concurrently.
The level of concurrency, part size, and threshold are all configurable
with reasonable defaults.
Using the multipart upload API has two benefits.
* The S3 Move method can now handle objects over 5 GB, fixing #886.
* Moving most objects, and espectially large ones, is faster. For
example, moving a 1 GB object averaged 30 seconds but now averages 10.

This is already supported by ncw/swift, so we just need to pass the
parameters from the storage driver.

Use the much faster math/rand.Read function where cryptographic
guarantees are not required. The unit test suite should speed up a
little bit but we've already optimized around this, so it may not
matter.

Previous component-wise path comparison is recursive and generates a
large amount of garbage. This more efficient version simply replaces the
path comparison with the zero-value to sort before everything. We do
this by replacing the byte-wise comparison that swaps a single character
inline for the separator comparison, such that separators sort first.
The resulting implementation provides component-wise path comparison
with no cost incurred for allocation or stack frame.
Direction of the comparison is also reversed to match Go style.

This adds the `--live-restore` option to the documentation.
Also synched usage description in the documentation
with the actual description, and re-phrased some
flag descriptions to be a bit more consistent.
