  Remove the signature from ref-modifying functions
  
  The signature for the reflog is not something which changes
  dynamically. Almost all uses will be NULL, since we want for the
  repository's default identity to be used, making it noise.
  
  In order to allow for changing the identity, we instead provide
  git_repository_set_ident() and git_repository_ident() which allow a user
  to override the choice of signature.
