[PATCH v2 0/5] Bulk Check-in

This is a re-roll of the earlier bulk-check-in series. The only change is that the last one is a bit re-structured to pay attention to the packsize limit from the get-go and also not write objects that already exist in the repository, instead of "oops, I forgot to do that, and here is a fix".

Junio C Hamano (5):
  write_pack_header(): a helper function
  create_tmp_packfile(): a helper function
  finish_tmp_packfile(): a helper function
  csum-file: introduce sha1file_checkpoint
  bulk-checkin: replace fast-import based implementation
