This sacrifices
- a little space (10 bytes),
- a few extra calculations, and
- introduces a dependency on strncmp()
to dramatically simplify the code of parsing methods and support almost
arbitrary extension methods.
In the future I will do as NGINX does and not use strncmp but bit level
blob comparisons.
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.
