Currently, containerd doesn't restart pull when it encounters unexpected EOF of
blob strem withtout error codes.
There are cases where this lead to pull failure.
This commit tries to fix this issue.

Schema1 manifests did not set a size in the digest for the blobs,
breaking the expectations of the update http seeking reader. Now
the http seeker has been updated to support unknown size as a
value of negative 1 and the schema1 puller sets the unknown size
accordingly.

To support resumable download, the fetcher for a remote must implement
`io.Seeker`. If implemented the `content.Copy` function will detect the
seeker and begin from where the download was terminated by a previous
attempt.
