/*
 * This release balances code size and performance. In particular key
 * schedule setup is fully unrolled, because doing so *significantly*
 * reduces amount of instructions per setup round and code increase is
 * justifiable. In block functions on the other hand only inner loops
 * are unrolled, as full unroll gives only nominal performance boost,
 * while code size grows 4 or 7 times. Also, unlike previous versions
 * this one "encourages" compiler to keep intermediate variables in
 * registers, which should give better "all round" results, in other
 * words reasonable performance even with not so modern compilers.
