  config: pass repository when opening config files
  
  Our current configuration logic is completely oblivious of any
  repository, but only cares for actual file paths. Unfortunately, we are
  forced to break this assumption by the introduction of conditional
  includes, which are evaluated in the context of a repository. Right now,
  only one conditional exists with "gitdir:" -- it will only include the
  configuration if the current repository's git directory matches the
  value passed to "gitdir:".
  
  To support these conditionals, we have to break our API and make the
  repository available when opening a configuration file. This commit
  extends the `open` call of configuration backends to include another
  repository and adjusts existing code to have it available. This includes
  the user-visible functions `git_config_add_file_ondisk` and
  `git_config_add_backend`.
