Perl: additional ctx->header_sent checks.
As we now have ctx->header_sent flag, it is further used to prevent
duplicate $r->send_http_header() calls, prevent output before sending
header, and $r->internal_redirect() after sending header.
Further, $r->send_http_header() protected from calls after
$r->internal_redirect().
