calloc, when multiplying to find the true size of memory desired
by a user, will occasionally overflow if the numbers are too
large. This commit makes calloc ensure that the multiplication
does not overflow by dividing the result by one of the numbers,
and checking to ensure that the result is equal to the other
number. If there is overflow, it is treated as an OOM error.
