requested review from
antonwolfy,
vlad-perevezentsev and
vtavana
as code owners
When a bad typenum is passed to functions which make usm_ndarrays from pointers, there was a possible underflow, as itemsize was declared size_t Instead declare itemsize as int and cast to size_t when needed (as itemsize should always fit in int)
