Switching to struct_size for the allocation in fifo_alloc avoids hard-coding the type of fifo_buffer.values in fifo_alloc. It also provides overflow protection; to avoid pessimistic code being generated by the compiler as a result, this patch also switches fifo_size to unsigned, propagating the change as appropriate.
