+Content-Length header

+
+## `Content-Length` with follow-up headers
+
+The way the parser works is that special headers (like `Content-Length`) first
+set `header_state` to appropriate value, and then apply custom parsing using
+that value. For `Content-Length`, in particular, the `header_state` is used for
+setting the flag too.
+
+Make sure that `header_state` is reset to `0`, so that the flag won't be
+attempted to set twice (and error).

+## Request with method starting with `H`
+
+There's a optimization in `start_req_or_res` that passes execution to
+`start_req` when the first character is not `H` (because response must start
+with `HTTP/`). However, there're still methods like `HEAD` that should get
+to `start_req`. Verify that it still works after optimization.
