http: server callback API simplified

This simplified API lets callbacks obtain the response from the
connection objection directly, and does not require the aio to carry
it as a parameter.  Further, the request and response are both
stored inline in the connection, reducing allocations.

This is at present only for the server; the client will get a similar
set of changes.
