[RFC/PATCHv8 00/10] git notes

Hi,

Here is the 8th iteration of the git-notes series. Changes in this
iteration are as follows:

Changes to existing patches:
- Rebased onto current 'next', dropping the early part of this series
  which has now been merged to 'next'.
- Patch 8 (was patch 22): Major rewrite of fast-import's notes handling
  code based on comments from Shawn.

New patches:
- Patch 9: Rename t9301 to t9350, to make room for more fast-import tests
- Patch 10: More fast-import tests

TODO:
- Builtin-ify git-notes shell script to take advantage of notes API
- Garbage collect notes whose referenced object is unreachable (gc_notes())
- Handle note objects that are not blobs, but trees


Have fun! :)
