#11584: Since __getitem__ returns headers, make decode_header handle them.

Browse source 
Why I consider this a bug rather than an API change: the API change was
to Message, which didn't used to return Headers unless you added them
yourself.  Now it does (for 8bit binary header input), so decode_header
needs to be able to handle them.
