[ostree: 56/70] ostree-repo-pull: always initialize flags_i

[Colin Walters <walters src gnome org>]

commit b69fd11487cfa23ff930da6b80b73e03b0daabe3
Author: Jonathan Lebon <jlebon redhat com>

    ostree-repo-pull: always initialize flags_i
    
    Otherwise we get undefined behaviour if the client didn't explicitly set
    any flags.
    
    Also, add documentation for all the other options supported by
    ostree_repo_pull_with_options().
    
    Closes: #252
