protogen: compute package names, import paths, generated filenames

Copy/duplicate the logic in github.com/golang/protobuf for computing
package names and import paths and the names of generated files.

This is all sufficiently complicated that the code is the best
documentation. In practice, users should always set a go_package option
containing an import path in every file and pass the
paths=source_relative generator flag to get reasonable behavior.

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.
