Super basic HTTP server. Listens for connections and always returns
404, using PION's default "not found" handler.

In order for the code to work PION has be build without log support.
I tried to make it work with log4cplus, but didn't want to spen too much
time figuring out how to configure the log system. Withouth configuring
the log system the application was crashing. Thus I deactivate logging
capabilities. Will be fixed in the future though.
