fortuna/entropy_src.h
surtur 03578f9016
All checks were successful
continuous-integration/drone/push Build is passing
accumulator: refactor entropy_src,add files
* add event_scheduler_impl.h and properly override its base class
* add urandom_entropy_src.cpp, move there logic from header
* add urandom_entropy_src.cpp to CMakeLists.txt
* add unique_ptr per impl: one for both EventSchedulerImpl and
  EventAdderImpl each
* wrap a call in reinterpret_cast and reformat code
* add missing includes (best effort)
