Commit d6a46fe8c264b5853ccf8f966f7bd00c1c32c877

Authored by aurel32

Add helper macros for later patches. 

Remove N_ELEMS, VECTOR_FOR, and VECTOR_FOR_I macros.  Retain the
VECTOR_FOR_INORDER_I macros as the clearest way of expressing the intent
of iterating over elements in their stored target-endian order.
