DocumentMapper exposes root() and meta() methods, which can be accessed through the mapping() method which exposes the entire Mapping instance. This commit removes such redundant methods in favour of accessing mapping and retrieving root and meta from them. Additionally, access to Mapping's members is made consistent through getters rather than package private fields in some cases and getters is some other case.

I'm pretty sure all this can just be replaced with a static set of an IdFieldMapper, SeqNoFieldMapper and VersionFieldMapper, but that can be done in a followup.

yes this is all a bit confusing, it seems very delicate too as in some places we need them sorted, in others we need the map by class, in others we retrieve them by name. I also wonder if we can further clean up DocumentMapper around retrieving metadata mappers.
