In 41cb7488 Linus moved this function to connect.c for reuse inside
of the git-clone-pack command. That was 2005, but in 2006 Junio
retired git-clone-pack in commit efc7fa53. Since then the only
caller has been fetch-pack. Since this ACK/NAK exchange is only
used by the fetch-pack/upload-pack protocol we should move it back
to be a private detail of fetch-pack.
