We found some examples of manifests with URLs specififed that did
not provide a digest or size. This breaks the security model by allowing
the content to change, as it no longer provides a Merkle tree. This
was not intended, so explicitly disallow by tightening wording.

The correct `vairant` string for ARM v6 is "v6", not "armv6l".
There is no known implementation that actually uses "armv6l".

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.

This is a follow-on to PR #62, and it borrows much of the format
from #993, but uses specific formats for the image manifest and manifest
list (fat manifest) instead of a combined generic format.
The intent of this proposed manifest format is to allow multi-arch, and
allow for full content-addressability of images in the Docker engine.
