CPU Jitter RNG (Random Number Generator) from the Jitterentropy library

A non-physical non-deterministic ("true") RNG (e.g., an entropy source
compliant with NIST SP800-90B) intended to provide a seed to a
deterministic RNG (e.g., per NIST SP800-90C).
This RNG does not perform any cryptographic whitening of the generated
random numbers.
