7e5a3650fe LibTest: Add the RandomnessSource abstraction 
This will be a foundational part of bootstrapping generators: this is
the way they'll get prerecorded values from / record random values into
RandomRuns. (Generators don't get in contact with RandomRuns
themselves, they just interact with the RandomnessSource.)

d4e4189a34 LibTest: Add the RandomRun abstraction 
To be used later by generators and during shrinking.

The generators used in randomized tests will record the drawn random
bits into a RandomRun. This is a layer of indirection that will help us
automatically shrink any generated value without any user input. (Having
to provide manually defined shrinkers is a downside to many randomized /
property-based testing libraries like QuickCheck for Haskell.)
