http.protocol: Support filehandlers for unhandled encodings

Browse source 
The setfilehandler() functions used for mime and url encoded message
bodies all operate with a signature of fh(meta, chunk, eof), but for
unhandled encodings, the callback was directly assigned to the sink
function, which has a signature of snk(chunk).  Insert a wrapper to
properly generate the EOF flag, and include a stub "meta" block
providing a virtual "name" and also the original client provided
Content-Type header, to possibly help with taking alternative actions in
the file handler.

The sink function created for raw content decoding also used the wrong
signature for the sink function.
