[RFC PATCH v3 04/17] Move "get_ack()" back to fetch-pack

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 keep move it back to a private detail of fetch-pack.
