A simple libevent http get server example

I recently tried to serve json queries in the "lightest" way, with a simple C program, with as little overhead as possible (no fcgi module, no scripting, standalone).

It happens that libevent has already all one need to do just that: answer http queries with as little overhead as possible, laid on an efficient networking library.

The trouble is, there is some documentation, but not that much, and a few pieces are missing to write a simple GET http server.

So, here is a skeleton for a simple GET http server with libevent.
It's handy for a very simple GET json server for instance.

Just in case that's of any help.
