Some common interfaces / abstract classes for SBE codecs

[RichardWarburton]

If you're writing a library or framework that uses SBE codecs it's very hard to abstract over common operations from SBE codecs. This could be resolved with the addition of a common interface or abstract class. The kind of common operations that would be useful to abstract over would be:

• int sbeBlockLength()
• StringBuilder appendTo(final StringBuilder builder)
• int sbeTemplateId()
• int sbeSchemaId()
• int sbeSchemaVersion()
• Encoder wrap(final MutableDirectBuffer buffer, final int offset)
• Encoder wrapAndApplyHeader( final MutableDirectBuffer buffer, final int offset, final MessageHeaderEncoder headerEncoder)

I'm happy to spend time to implement this - I don't think it would take long to be honest but I wanted to open an issue for feedback / discussion before starting.

Most of these already exist.

Thanks for pointing that out @mjpt777 - is there a configuration option that I need to use in order to generate them? At the moment all the codecs that I've seen generated don't implement these interfaces.

Thanks.
