Continuation of 97002b684c. This makes
the daemon use constant memory. For example, it reduces the daemon's
maximum RSS on
$ nix copy --from ~/my-nix --to daemon /nix/store/1n7x0yv8vq6zi90hfmian84vdhd04bgp-blender-2.79a
from 264 MiB to 7 MiB.
We now use a TunnelSource to prevent the connection from ending up in
an undefined state if an exception is thrown while the NAR is being
sent.
