  Reorganize diff and add basic diff driver
  
  This is a significant reorganization of the diff code to break it
  into a set of more clearly distinct files and to document the new
  organization.  Hopefully this will make the diff code easier to
  understand and to extend.
  
  This adds a new `git_diff_driver` object that looks of diff driver
  information from the attributes and the config so that things like
  function content in diff headers can be provided.  The full driver
  spec is not implemented in the commit - this is focused on the
  reorganization of the code and putting the driver hooks in place.
  
  This also removes a few #includes from src/repository.h that were
  overbroad, but as a result required extra #includes in a variety
  of places since including src/repository.h no longer results in
  pulling in the whole world.
