Trashing the old Ragel parser (which was based on Mongrel) because it's
proving difficult to get the control I need in end-of-message cases.
Replacing this with a hand written parser using a couple tricks borrowed
from NGINX. The new parser will be much more work to write, but should prove
faster and allow for better hacking.
And much more:
* Begin the framework for parsing HTTP responses
* Modify the test code with the new layout
* Remove EBB_ prefix and use just HTTP_
* Start simple new Makefile
Currently the test passes but it is only checking HTTP requests. I get the
feeling that it is much slower than before, although I have no solid
evidence for this.
