[PATCH 0/4] Bulk check-in

This miniseries is a continuation of the "large file" topic from 1.7.6 development cycle.

The first three are moving existing code around for better reuse. The last one serves two purposes: to lift the one-pack-per-one-large-blob constraint by introducing the concept of "plugging/unplugging" (i.e. you plug the drain and throw many large blob at index_fd(), and they appear in a single pack when you unplug it), and to stop using fast-import in this codepath.

Only very lightly tested.

Junio C Hamano (4):
  write_pack_header(): a helper function
  create_tmp_packfile(): a helper function
  finish_tmp_packfile(): a helper function
  Bulk check-in
