HTTP forwarded and contentDisposition + parsing improvements

on GitHub

This patch was authored and released by @tanner0101.

Adds support for parsing HTTP forwarded header: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Forwarded

req.headers.forwarded.first?.for // String?

This includes support for:

• Forwarded
• Via
• X-Forwarded-For
• X-Forwarded-Host
• X-Forwarded-Proto

Adds support for parsing HTTP content disposition headers: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition

req.headers.contentDisposition?.filename // String?

These are implemented by a new HTTPHeaders.DirectiveParser for handling the complexities of HTTP header parsing like quoted strings, whitespace, etc. The new HTTPHeaders.DirectiveSerializer handles serialization. HTTPHeaderValue has been deprecated.
