Mapping: Moved dynamic field handling in doc parsing to end of parsing
Currently dynamic mappings propgate through call semantics, where deeper dynamic mappings are merged into higher level mappings through return values of recursive method calls. This makese it tricky to handle multiple updates in the same method, for example when trying to create parent object mappers dynamically for a field name that contains dots. This change makes the api for adding mappers a simple list of new mappers, and moves construction of the root level mapping update to the end of doc parsing.
