Rewrite GenSources including full support for CFR. (#511)

* Rewrite CFR decompiler interface. Support javadoc

* CFR line numbers and fixes.

* Cleanup and fix

* Use WorkerExecutor to fork, massively cleans up the fernflower code, but does remove the fancy multithreaded logging.

* Use IPC to get logging back from the decompilers.

* Cleanup UnpickJarTask, fix leak in IPCServer

* Used published CFR build

* Handle older windows versions that do not support AF_UNIX.

* Fixes and basic unit test

* Improve memory handling of genSources

* Stop decompile worker JVM
