Array: avoided void pointer arithmetic in nxt_array_copy().archive/arithOperationsOnVoidPointer
As was pointed out by the cppcheck[0] static code analysis utility we
were doing void pointer arithmetic on src->elts which is technically
undefined behaviour.
While GCC allows this by treating the size of void as 1[1]. Same with
Clang. Other compilers I'm not sure about, so lets just be safe and cast
src->nelts to (char *) where sizeof(char) is guaranteed to be 1.
