[PATCH v2 0/4] Improvements to sha1_file

Peff suggested putting in a new field in struct object_info for the object contents; I tried it and it seems to work out quite well.

Patch 1 is unmodified from the previous version. Patches 2-3 have been rewritten, and patch 4 is similar except that the missing-lookup change is made to sha1_object_info_extended() instead of the now gone get_object().

As before, I would like review on patches 1-3 to go into the tree. (Patch 4 is a work in progress, and is here just to demonstrate the effectiveness of the refactoring.)

Jonathan Tan (4):
  sha1_file: teach packed_object_info about typename
  sha1_file: move delta base cache code up
  sha1_file: consolidate storage-agnostic object fns
  sha1_file, fsck: add missing blob support
