Allow clients to handle errors being set in the WWW-Authenticate
rather than in the body. The WWW-Authenticate errors give a
more precise error describing what is needed to authorize
with the server.

If a user specifies `mydomain.com:443` in the `Host` configuration, the
PATCH request for the layer upload will fail because the challenge does not
appear to be in the map. To fix this, we normalize the map keys to always
use the Host:Port combination.

make a GET request for cases:
- if the server does not handle HEAD
- if the response was an error to get error details

go1.5 doesn't export http.StatusTooManyRequests while
go1.6 does. Fix this by hardcoding the status code for now.

If this slice ends up empty after parsing the HTTP response body, it
means the body is not well-formed. We've probably encountered an error
message produced by something that uses a different JSON schema, or
an error that just happens to validate as JSON.
An empty errcode.Errors slice is not a very useful thing to return,
since its Error() output is just `<nil>`. Detect this case, and instend
return an UnexpectedHTTPResponseError.

A changeset under consideration for Go 1.7 would automatically copy
headers on redirect. This change future-proofs our code so we won't make
duplicate copies of the headers if net/http does it automatically in the
future.
