Bring echo and more shell style goodies to Nginx

Echo module wraps lots of Nginx internal APIs for streaming input and output, parallel/sequential subrequests, timers and sleeping, as well as various meta data accessing.

Basically it provides various utilities that help testing and debugging of other modules by trivially emulating different kinds of faked subrequest locations.

People will also find it useful in real-world applications that need to:

1. Serve static contents directly from memory. 2. Wrap the upstream response with custom header and footer (kinda like the

   addition module but with contents read directly from the config file and
   Nginx variables).

   a single main request (using echo_location and its friends).
