Merge #15224: Add RNG strengthening (10ms once every minute)
3cb9ce85d0c6d01217babf0df7efc2eabde1b12f Document strenghtening (Pieter Wuille)
1d207bc46f995ad3b5ae89bb504affaca09d10b1 Add hash strengthening to the RNG (Pieter Wuille)
Pull request description:
This patch improves the built-in RNG using hash strengthening.
At startup, and once every minute, 32 bytes of entropy are produced from the RNG, repeatedly hashed using SHA512 for 10ms, and then fed back into the RNG, together with high-precision timestamps obtained every 1000 iterations.
