Rock Solid mode

The ROCK_SOLID mode, is a compilation flag that create a uwsgi server without all the potential dangerous (or less useful) functions turned off.

The ROCK_SOLID flag disable threading, multiple interpreter, sendfile, memory logging, cgi mode, xml config file, multiple app, python optimization and the integrated profiler.

Its syntax is a lot simpler, instead of defining a config file you pass the wsgi script to the commandline:

./uwsgi_rs -s /tmp/uwsgi.sock my_app

... where my_app is the wsgi script (named my_app.py)
