generator: stop hex-encoding bytes in do_crypto() 
in fortuna, print the random bytes as they come, without a newline, to
stdout. the idea is it can be directly piped to, say, dieharder, for,
e.g. testing purposes. also print info msg to stderr as is now customary
throughout the program.

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)

add Util class + perform general refactor 
* rm duplicate do_sha() code, consolidate in Util
* make reseed() public so that it can be called from outside
* rm reseed() from do_crypto() where it has no place

fix(generator): incorrect copying, no protections 
* use try-catch whenever possible
* perform memcpy operations in the right direction
* make greater use of local constants
* use more of the braced initializations
* there were memcpy operations of incorrect sizes in place, particularly
  in regard to generator key (G.k) and counter (G.ctr), which resulted
  in key bytes being set to garbage

finalise generator 
commit a64b52e5a4
Author: surtur <a_mirre@utb.cz>
Date:   Sun Nov 21 23:39:30 2021 +0100

    finalise generator

    this commit adds a (nearly) complete implementation of the generator.

    * wrap calls to generator in a fortuna class method random_data
      * calls generator's method generate_random_data, that internally calls
        generate_blocks
    * use a proper 256bit key in G_state
    * add reseed method implementation
    * call a reseed in initialize_generator
    * do_sha returns proper digest now
    * add proper do_crypto implementation
      * call generate_blocks internally
      * handle re-keying
    * optimise header includes

    TODO: there are still many commented (enabled on demand) debugging statements
    -> TO BE REMOVED
