inconsistent handling of keywords and conflicts

[fowles]

Various code generators and languages have interesting non-overlapping sets of keywords. Protobuf as a whole does not handle these things consistently (sometimes it mangles them, sometimes it generates code that doesn't compiler). When the mangling causing conflicts with other feels we are one again inconsistent. Then we are sad.

What needs to happen is a systematic push to

1. figure out what we do now
2. propose a unified solution
3. move things to it

Adding my recent encounter with this issue with Java/Kotlin compilation where the case keyword in a package name generated non-compiling code, it also made me sad 🥲
