add new Appender and Message API

- deprecated old Message, add new IMessage API.
- deprecated old Logger.appends, uses new AppenderProvider API to provide Appenders to Logger.
- add a context on Log.
- deprecated field read on Log, use method to read those.
- add name on Logger.
- add codepoint output for SimpleFormatter.
