array_cat - append one array to another

       array_cat appends y to x; i.e., it changes x, allocating more space if necessary, so that the initialized
       bytes in x are the previously initialized bytes in x followed by a copy of the initialized bytes in y.

       If x has failed, array_cat has no effect.

       If y has failed, array_cat switches x to have failed.

       If not enough memory is available, array_cat switches x to have failed.
