*) Feature: the "try_files" directive supports a response code in the
fallback parameter.
*) Feature: now any response code can be used in the "return" directive.
*) Bugfix: the "error_page" directive made an external redirect without
query string; the bug had appeared in 0.7.44.
*) Bugfix: if servers listened on several defined explicitly addresses,
then virtual servers might not work; the bug had appeared in 0.7.39.
