Kill the_index part 5

(Please ignore v1 which contains unrelated patches)

I lied about part 5 being final. This series contains most of my WIP series [2] except sha1-name.c, read-cache.c and merge-recursive.c because there will be conflicts on 'pu' so they will be in part 6. At least this only results in two small conflicts in sequencer.c.

I did start pushing the_repository out of library code [1] in the bottom half of this series. There aren't big surprises except that cache-tree API now take _both_ struct repository and struct index_state. The reason is cache-tree can work on temporary indexes and repo->index is about $GIT_DIR/index.

[1] Stefan and I make a good team. He keeps adding the_repository. I keep removing. We both hold hands leading commit counts (with Brian just a bit behind frantically replacing sha1 with oid to keep up). Meanwhile Junio is crying in the corner because of too many conflicts. :-D
