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)

add proper SeedFileManager implementation 
a couple of fixes/necessary additions were made along the way, namely:
* add a default constructor for DoTask
* rework of the mutex/lock_guard/unique_lock logic in generator/fortuna
* add .fortuna.seed to the list of the ignored (.gitignore)
* add helper function to util for convertin bytes to blocks (16b==block)
* add a wrapper for around the SeedFileManager instance and a way to see
  if it's dead or alive (so that it can be restarted if needed)
* the timeout for saving of the seed file has been decreased to a more
  reasonable value than 10 minutes (I wouldn't want to lose potentially
  up to 10 minutes worth of entropy)

integrate clang-tidy into cmake 
* consolidate everything with the makefile, the "tidy" target now just
  sets the env var that is checked for in CMakeLists
* rm clang-tidy from pre-commit as it's run as part of the "test"
  makefile target later in the file anyway

handle PRNG state in R_state + accumulator basis 
* handle the PRNG state with R_state nested class
* add a private property R holding PRNG state to Fortuna
* add R_state properties as defined in Cryptography Engineering:
  * a generator instance
  * a reseed counter
  * 32 pools that the collected entropy is to be distributed over

* add initial definition of the Pool object and its initialization

* attempt to initialize PRNG in Fortuna constructor. wrap the
  initialization call in a try-catch block like a cultured person
* erase the string used to print data from random_data() after it's been
  used
