[PATCH v2 3/6] cli: config: keep track of whether the config is newly created

[Jani Nikula]

Keep track of whether the config is newly created, and add
notmuch_config_is_new() accessor function to query this.

This is to support anyone with a config handle to check this, instead
of just whoever called notmuch_config_open().
