Make the process running entropy source much faster by running multiple commands
in parallel. On my laptop, a reseed using only process running takes .22 s wall
clock in trunk and .06 s with this change - and that's after increasing the
amount we read by 5 times (by reducing the entropy estimate per byte from .005
bits to 1/1024 bits).
Fix EGD settings. Some cleanup and renaming.
Don't actually deprecate AutoSeeded_RNG
Create RNG early so it is easy to check reseed times
Include a timestamp as part of the HMAC_RNG PRF inputs
