  Remove redundant methods from the API A bunch of redundant methods have been removed from the external API. - All the reference/tag creation methods with `_f` are gone. The force flag is now passed as an argument to the normal create methods. - All the different commit creation methods are gone; commit creation now always requires a `git_commit` pointer for parents and a `git_tree` pointer for tree, to ensure that corrupted commits cannot be generated. - All the different tag creation methods are gone; tag creation now always requires a `git_object` pointer to ensure that tags are not created to inexisting objects.
