wireprotov2: server support for sending content redirects
A "content redirect" can be sent in place of inline response content.
In terms of code, we model a content redirect as a special type of
response object holding the attributes describing that redirect.
Sending a content redirect thus becomes as simple as the object
emission layer sending an instance of that type. A cacher using
externally-addressable content storage could replace the outgoing
object stream with an object advertising its location.
The bulk of the code in this commit is teaching the output layer
which handles the object stream to recognize alternate location
objects. The rules are that if an alternate location object is
present, it must be the first and only object in the object stream.
Otherwise the server emits an error.
