This commit improves the fallback behaviour when resolving and
fetching images with multiple hosts. If an error is encountered
when resolving and fetching images, and more than one host is being
used, we will try the same operation on the next host. The error
from the first host is preserved so that if all hosts fail, we can
display the error from the first host.

Docker registries return errors in a know format so this change now checks for these
errors and returns the message field. If the error is not in the expected format fall
back to the original behaviour.

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.

Add support for downloading layers with external URLs and
foreign/non-distributable mediatypes. This ensures that encountered
windows images are downloaded correctly. We still need to filter out the
extra windows resources when pulling linux, but this is a step towards
correctly supporting multi-platform images.
