rand: new-style locking and support rdrand.
Pure /dev/urandom, no buffering (previous behaviour):
Did 2320000 RNG (16 bytes) operations in 3000082us (773312.2 ops/sec): 12.4 MB/s
Did 209000 RNG (256 bytes) operations in 3011984us (69389.5 ops/sec): 17.8 MB/s
Did 6851 RNG (8192 bytes) operations in 3052027us (2244.7 ops/sec): 18.4 MB/s
Pure rdrand speed:
Did 34930500 RNG (16 bytes) operations in 3000021us (11643418.5 ops/sec): 186.3 MB/s
Did 2444000 RNG (256 bytes) operations in 3000164us (814622.1 ops/sec): 208.5 MB/s
Did 80000 RNG (8192 bytes) operations in 3020968us (26481.6 ops/sec): 216.9 MB/s
rdrand + ChaCha (as in this change):
Did 19498000 RNG (16 bytes) operations in 3000086us (6499147.0 ops/sec): 104.0 MB/s
Did 1964000 RNG (256 bytes) operations in 3000566us (654543.2 ops/sec): 167.6 MB/s
