Already loaded NGINX modules

[Yichun Zhang (agentzh)]

Hi guys!

Currently when an NGINX module is statically linked against the NGINX
binary, the load_module directive bails out the server startup with
the error message "module already loaded" (or something like that).
Hopefully we can make this a nonfatal error (or provide an option to
make it nonfatal) because we can have more portable nginx.conf for
distributing NGINX-based applications.

Thanks for your attention!

Best regards,
