Subject: [PATCH] mod_lua: Make r.ap_auth_type writable

This completes the option of setting the remote user by the authentication
mechanism which actually verified the user.

One possible usecase is that a proxied (upstream) server performs the
authentication, but the access log of HTTPd does not contain this information.
The upstream server can pass this kind of information back to HTTPd and both
servers will have consistent access logs.
