kcar features an HTTP parser that will convert a bytestream into a
3-element array suitable for use as a Rack response. It is IO interface
agnostic, so it may be used with HTTP streams over Unix domain sockets,
regular files, FIFOs, StringIOs as well as traditional TCP sockets.

This provides some extra type safety if combined with other
C extensions, as well as allowing us to account for memory usage of
the HTTP parser in ObjectSpace.
This requires Ruby 1.9.3+ and has remained a stable API since
then. This will become officially supported when Ruby 2.3.0 is
released later this month.
This API has only been documented in doc/extension.rdoc (formerly
README.EXT) in the Ruby source tree since April 2015, r50318

Mainly modernizing and stealing some features from unicorn,
and perhaps prototyping some new ones.
Will still need to shrink the struct a bit while ensuring
we don't exceed limits and such.
