Motivation: The commit 50e06442c3f2753c9b2a506f68ea70273b829e21 changed the type of the constants in HttpHeaders.Names and HttpHeaders.Values, making 4.1 backward-incompatible with 4.0. It also introduces newer utility classes such as HttpHeaderUtil, which deprecates most static methods in HttpHeaders. To ease the migration between 4.1 and 5.0, we should deprecate all static methods that are non-existent in 5.0, and provide proper counterpart. Modification: - Revert the changes in HttpHeaders.Names and Values - Deprecate all static methods in HttpHeaders in favor of: - HttpHeaderUtil - the member methods of HttpHeaders - AsciiString - Add integer and date access methods to HttpHeaders for easier future migration to 5.0 - Add HttpHeaderNames and HttpHeaderValues which provide standard HTTP constants in AsciiString - Deprecate HttpHeaders.Names and Values - Make HttpHeaderValues.WEBSOCKET lowercased because it's actually lowercased in all WebSocket versions but the oldest one - Add RtspHeaderNames and RtspHeaderValues which provide standard RTSP constants in AsciiString - Deprecate RtspHeaders.* - Do not use AsciiString.equalsIgnoreCase(CharSeq, CharSeq) if one of the parameters are AsciiString - Avoid using AsciiString.toString() repetitively - Change the parameter type of some methods from String to CharSequence Result: Backward compatibility is recovered. New classes and methods will make the migration to 5.0 easier, once (Http|Rtsp)Header(Names|Values) are ported to master.
