internal/impl: initial commit

This provides an implementation of the has, get, set, clear methods for each
field in a message. The approach taken here is similar to the table-driven
implementation in the current v1 proto package.

The pointer_reflect.go and pointer_unsafe.go files are a simplified version of
the same files in the v1 implementation. They provide a pointer abstraction
that enables a high-efficiency approach in a non-purego environment.
The unsafe fast-path is not implemented in this commit.

This commit only implements the accessor methods for scalars using pure
Go reflection.

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.
