Add entropy pool and strong random number generator
...
Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output.
Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively.

Without lowsyslog() *llerr() is not useful. Eliminate and replace with *err().

Unify sensor debug. ADX driver was using input debug; LM75 and QENCODE that their own custom debug. Now all use CONFIG_DEBUG_SENSOR, sndbg()
