There is a new protobuf library (and corresponding code generator) for
Go: google.golang.org/protobuf.
It is fairly compatible with the previous v1 API
(github.com/golang/protobuf), but there are some changes.
This patch adjusts the code and generated files to the new API.
The on-wire/on-disk format remains unchanged so this should be
transparent to the users.
This patch updates the auto-generated code to match the latest tooling
versions.
In particular, the protobufs are regenerated, and the new version no
longer supports unkeyed literals, so some minor changes are needed.
Other than that, the cipher list is extended with the latest ciphers.
This is just a run of "go generate ./..." which re-generates the protocol
buffers code.
There is no actual change in the logic or APIs, it's just a rebuild with a
newer proto compiler. While it's not strictly necessary, it will help make
subsequent patches cleaner.
