+/*
+ * 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.
