MaybeReadByte function #

MaybeReadByte reads a single byte from r with 50% probability. This is used to ensure that callers do not depend on non-guaranteed behaviour, e.g. assuming that rsa.GenerateKey is deterministic w.r.t. a given random stream. This does not affect tests that pass a stream of fixed bytes as the random source (e.g. a zeroReader).
