[PATCH 0/4] Fetching mass of objects at once

  Hi,

  this series implements support for fetching many objects at once with
git-local-fetch and git-http-fetch, greatly helping Cogito's performance.  It
would be of course nice to have this in Git 1.4.2, but it's probably too late
for that.

  I didn't bother to convert git-ssh-fetch since I think noone uses that
anymore anyway (why would they...), or only some legacy users do.

  I will followup with a patch for Cogito to take advantage of this. It's
now roughly on par with Git in cloning speed.
