This patch does a general pass updating Go modules to recent versions,
and regenerates the protobufs accordingly.
The main purpose is to make sure people building from source are using
relatively recent versions of our dependencies.
We also regenerate protobufs since the newer versions of the liberaries
have a much cleaner dependency tree, which speeds up fetches.
The queue protobuf definition currently uses the well-known timestamp
protobuf package.
This adds a build-time dependency on it, which is fairly harmless when
building from source (since the golang protobuf compiler includes it
already), but adds overhead for packaging on distributions.
Since this is the only external proto dependency we have, and the
protobuf message itself is trivial, this patch removes it an instead
embeds a compatible definition.
That way we remove the dependency and simplify packaging, with almost
negligible code overhead.
The change is fully backwards compatible and has no functional changes.
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.
