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.
