internal/impl: change unmarshal func return to unmarshalOptions

The fast-path unmarshal funcs return the number of bytes consumed.

Change these functions to return an unmarshalOutput struct instead, to
make it easier to add to the results. This is groundwork for allowing
the fast-path unmarshaler to indicate when the unmarshaled message is
known to be initialized.

Next Generation Go Protocol Buffers

WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.

This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
