Subject: Rename unicorn/http11 => unicorn_http

We couldn't do proper namespacing for the C module so there was
a potential conflict with Init_http11() in Mongrel.  This was
needed because Mongrel's HTTP parser could be used in some
applications and we may be unfortunate enough need to support
them.
