[PATCH 00/17] convert ls-files internals to pass around an index

This is the second chunk of patches I want to carve off of my 'repository object' series. As you can see its 17 patches long so by eliminating this the repository series shrinks by a considerable amount.

The point of this series is to stop having some of the internals of ls-files (and subsequent library routines) from implicitly referencing 'the_index'. Instead a pointer to an 'index_state' struct is passed around and operated on. This is a preparatory step to enabling ls-files to able to recurse submodule in-process. They other step being the actual introduction of a repository object.
