* [PATCH v1 3/4] Add alias to be used as "unset" state.

Add `unset_alias` string parameter to trenary reloption definition. This will allow
user explicitly switch trenary option to "unset" state. Use this feature to
implement `vacuum_index_cleanup` and gist's `buffering` reloptions as trenary
reloptions
