Title: HPCC-3286 Provide new helper function to estimate row memory consumption

Add a new getExpectedFootprint function to estimate the amount of memory
that an allocation of a given size will actually require.

Also includes a fix to getExpectedCapacity for a packed row (probably
unused at the moment), and remove a VS warning about a double/size32_t
conversion.
