Changes for version 2.24
- bring cookie management more in line with RFC 6265; implement idn matching for cookie domains.
- update cookie_jar version to 2, invalidate existing cookie jars.
- preserve original cookie domain attribute.
- also expire old cookie jars in cookie parser, just in case.
- further improve relative redirection code.
- comment out code that tried to detect possible bugs with persistent connection caching, but since it never triggered, it's probably working fine :)
- do not call on_body callback on a response that AE::HTTP will recurse on internally (reported by Антон Онуфриев and Ruslan Zakirov).
