Make rte_rand() multi-thread safe, go faster and produce better-quality pseudo-random numbers.
v2: * Removed 32-bit version of rte_rand() and rte_rand_max(). * Switched from a four-sequence LFSR (producing a 32-bit number) to a five-sequence LFSR (producing a 64-bit number). * Added a note on generator not being cryptographically secure.
