[djungelorm]

This is a status summary of the refactoring effort to support kRPC2.

Design document: https://docs.google.com/document/d/1KaNmLeUIJCPs2W7tWRvxPb9dLSLsHMupzUVJw6O9_Sc/edit?usp=sharing

Tasks:

• Split "core" code out of the server directory to a new directory called core, and associated tests
• Copy "core" code, and common tools to krpc-core repository along with git history
• Update this krpc repository to depend on krpc-core, removing the duplicate code from here
• Move relevant issues from here to the krpc-core repository
• Update krpc2 repository to depend on krpc-core
• Move client libraries to their own repositories
  • krpc-csharp
  • krpc-python
  • krpc-cpp
  • krpc-cnano
  • krpc-java
  • krpc-lua

As things are migrated to their own repositories:

• Update build scripts to use cross platform compatible rules Use bazel rules to simplify build scripts #694
• Add GitHub CI workflow to run tests
• Ensure build works on Linux and Windows
• Migrate issues specific to a particular component to it's repository
