I also un-deprecated these while in here. I was mistaken when I wrote this comment: the protobuf runtime does not verify that import paths are correct. Instead it will happily delay the errors until you need to use reflection. At reflection time, it can provide "placeholder" descriptors for files that are imported using the wrong name. So all of the work-arounds in this file for patching import paths are, in fact, still useful.

Some other low-hanging fruit clean-up while in here.
…re better named and allow returning an error

The
desc/sourceinfopackage previously wrapped descriptors, by returning an implementation of the variousprotoreflect.Descriptorinterfaces that embedded the original descriptor values. However, these various interfaces are all defined as "do not implement". So, to avoid future issues where the protobuf runtime may type-assert implementations to their own internal types (which would panic/fail with the concrete wrapper types in this package), we no longer wrap this way.This also happens to resolve #618 (since there's no more wrapping, an incorrect typed-nil wrapper can't escape).
