Nix version protocol

In commit be64fbb501 support was droped for protocol versions older than 1.10. This happened when the protocol was between 1.17 and 1.18 and was released with Nix 2.0. So this means that any version of Nix 2.x can't talk to Nix 0.x.

Operation History

Notes: Ops that start with * have been removed. Protocol version that ends with * was bumped while adding that operation. Otherwise protocol version referes to the protocol version at the time the operation was added (so only at the next protocol version can you assume the operation is present/removed/obsolete since it was added/removed/obsoleted between protocol versions).
