* fix test to work w/ newer grpc repo; run 'make ci' to have it update go.mod and go.sum, trying to repro ci failure locally
* vet w/ go 1.13; use normal go proxy instead of direct in CI
Allows descriptors or proto files to be supplied that are used as an additional descriptor source when server reflection is used. This is needed to resolve message types embedded in an Any message, that the server has no knowledge of, as well as extensions that the server has no knowledge of.
With 1.4.0 the golang/protobuf json testing protofiles
are being moved to [an internal package][1]. While this is
technically a breaking change, I doubt the maintainers
are going to reintroduce it, so I've copied the necessary
parts to our own testing protofile.
This allows users of this package and, more importantly,
grpcui to try 1.4.0 without this package having to migrate yet.
When it comes to migrating to 1.4.0, this should also make the
transition easier.

* use wrapped TransportCredentials instead of handling handshake in Dialer, so that grpc library will use correct :scheme
* support -authority for TLS conns; now effectively supercedes -servername flag
To better support printing of google.protobuf.Any messages (error details), this
also makes a few other changes:
1. Allows printing of unresolvable Any messages using an "@value" field in JSON output
that has the base64-encoded embedded message data.
2. Improves support for "-format text" to show expanded Any messages if possible.
(Due to limitations in underlying proto package, this will usually *not* be
that helpful. But this should greatly improve with v2 of the go protobuf API.)
3. Addresses a TODO in existing AnyResolver code to lazily fetch descriptors
as needed instead of having to download all files eagerly.
* organize into multiple files
* make listing methods show fully-qualified names
* address small feedback from recent change (trim then check if empty)
