fix #171 Several names and HTTP identifiers are renamed to be more consistent, self-explanatory, and concise: * "Fields" is a collection of HTTP header fields (rfc7230 section 3.2) * "Header" is the Start Line plus Fields. Another way to look at it is, the HTTP message minus the body. * `basic_fields` replaces `basic_headers` * `fields` replaces `headers` * `Fields` replaces `Headers` in template parameter lists * `header` replaces `message_headers` * `header::fields` replaces `message_headers::fields` The changes are cosmetic and do not affect run-time behavior.
