array_length - get number of allocated members in array

       array_length  returns  the  number  of  initialized bytes in x, divided by the size of t. In other words,
       array_get will succeed for positions 0 through array_length-1; it will fail for position array_length.

       If x is unallocated, array_length and array_bytes return 0.
