proto: add MarshalState, UnmarshalState

Add functions to the proto package which plumb through the fast-path state.

As a sample use case: A followup CL adds an Initialized field to
protoiface.UnmarshalOutput, permitting the unmarshaller to report back
when it can confirm that a message is fully initialized. We want to
preserve that information when an unmarshal operation threads through
the proto package (such as when unmarshaling extensions).

To allow these functions to be added as methods of MarshalOptions and
UnmarshalOptions rather than top-level functions, separate the options
from the input structs.

Also update options passed to fast-path methods to set AllowPartial and
Merge to reflect the expected behavior of those methods. (Always allow
partial, never merge.)

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.
