Added support for IP-literal in the Host header and request line (ticket #1). Additional parsing logic added to correctly handle RFC 3986 compliant IPv6 and IPvFuture characters enclosed in square brackets. The host validation was completely rewritten. The behavior for non IP literals was changed in a more proper and safer way: - Host part is now delimited either by the first colon or by the end of string if there's no colon. Previously the last colon was used as delimiter which allowed substitution of a port number in the $host variable. (e.g. Host: 127.0.0.1:9000:80) - Fixed stripping of the ending dot in the Host header when the host was also followed by a port number. (e.g. Host: nginx.com.:80) - Fixed upper case characters detection. Previously it was broken which led to wasting memory and CPU.
