Some implementation mistakes in dnssec-oracle/BytesUtils.compare

There are implementation mistakes in dnssec-oracle/BytesUtils.compare which can lead to serious problems if not addressed. A sanity check for offsets and lens is missing, and the condition for checking the size of the last block is incorrect. The returned value disobey the developer's comment, and there should be caution for int underflow/overflow
