Merge branch 'ps/fetch-optim'

Optimize code that handles large number of refs in the "git fetch"
code path.

* ps/fetch-optim:
  fetch: avoid second connectivity check if we already have all objects
  fetch: merge fetching and consuming refs
  fetch: refactor fetch refs to be more extendable
  fetch-pack: optimize loading of refs via commit graph
  connected: refactor iterator to return next object ID directly
  fetch: avoid unpacking headers in object existence check
  fetch: speed up lookup of want refs via commit-graph
