Tim Ruffing a310e79ee5 Merge bitcoin-core/secp256k1#1052: Use xoshiro256++ instead of RFC6979 for tests 
77a19750b4 Use xoshiro256++ PRNG instead of RFC6979 in tests (Pieter Wuille)
5f2efe684e secp256k1_testrand_int(2**N) -> secp256k1_testrand_bits(N) (Pieter Wuille)

Pull request description:

  Just some easy low-hanging fruit. It's complete overkill to use the RFC6979 RNG for our test randomness. Replace it with a modern non-cryptographic RNG with good properties. It's a few % speedup for me.

  Given the internal naming of all these functions to be "testrand", I'm not concerned about the risk of someone using this for something that needs actual cryptographic randomness.
