When receiving a push, we advertise ref tips from any alternate repositories, in case that helps the client send a smaller pack. Since these refs don't actually exist in the destination repository, we don't transmit the real ref names, but instead use the pseudo-ref ".have".

If your alternate has a large number of duplicate refs (for example, because it is aggregating objects from many related repositories, some of which will have the same tags and branch tips), then we will send each ".have $sha1" line multiple times. This is a pointless waste of bandwidth, as we are simply repeating the same fact to the client over and over.

This series eliminates duplicate .have lines on push (we don't need to do so during fetch; see 3/3 for details).

  [1/3]: refactor refs_from_alternate_cb to allow passing extra data
  [2/3]: bisect: refactor sha1_array into a generic sha1 list
  [3/3]: receive-pack: eliminate duplicate .have refs
