+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).
