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)
* 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
* 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 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
switch to fmt - "A modern formatting library" - for fun and profit,
currently in header-only configuration.

the find "query" is a little naive but hey, we're looking at the usual
place. the purpose of this change is iteration speedup and as lld is the
quickest kid on the block, we're using it.
cmake:
* check if we're being run for valgrind, in which case do not split
dwarf information, valgrinds does not like it (see #1).
makefile:
* build for vagrant into a separate folder entirely.
ci:
* install gcc, cmake and ninja along with vagrant, since now we are
building inside of the ci container as well.
