docs: complete function reference, drop unicode punctuation

Documents refresh_hierarchy_cache, is_rule_valid and org_in_scope, and
corrects the get_org_scope scope list which still omitted unattributed
and all.

Replaces em dashes and other typographic unicode with ASCII throughout
the schema comments, the test suite and the documentation. Comments and
prose are ASCII only.
