From: Ethan Glasser-Camp <ethan@betacantrips.com> This is part of notmuch-new refactor phase 1: make add_files stuff safe for other backends. add_files_recursive is essentially a maildir-crawling function that periodically adds files to the database or adds filenames to remove_files or remove_directory lists. I don't see an easy way to adapt add_files_recursive for other backends who might not have concepts of directories with other directories inside of them, so instead just provide an add_files method for each backend. This patch pulls some bits out of add_files_recursive which will be useful for other backends: two reporting functions _report_before_adding_file and _report_added_file, as well as _add_message, which actually does the message adding.
