- Add ChannelHandlerUtil and move the core logic of ChannelInbound/OutboundMessageHandler to ChannelHandlerUtil
- Add ChannelHandlerUtil.SingleInbound/OutboundMessageHandler and make ChannelInbound/OutboundMessageHandlerAdapter implement them. This is a backward incompatible change because it forces all handler methods to be public (was protected previously)
- Fixes: #1119
- Borrow SLF4J API which is the best of the best
- InternalLoggerFactory now automatically detects the logging framework
using static class loading. It tries SLF4J, Log4J, and then falls back
to java.util.logging.
- Remove OsgiLogger because it is very likely that OSGi container
already provides a bridge for existing logging frameworks
- Remove JBossLogger because the latest JBossLogger implementation seems
to implement SLF4J binding
- Upgrade SLF4J to 1.7.2
- Remove tests for the untestable logging frameworks
- Remove TestAny
