Daniel Verkamp d3c28cc3c1 data_model: windows: panic if IoBuf len is too large 
The Windows version of IoBuf uses the WSABUF structure, which represents
len as a 32-bit value. Previously, larger len values would be silently
truncated; this change makes those conversions using try_into() instead.
We have no easy way to report failure of this usize -> u32 conversion,
so for now, just unwrap() to cause a panic if the length ever overflows
so it will at least produce a crash report and be noticed.

A possible future enhancement could be to make all relevant IoBuf and
IoBufMut functions return Result<...> so the error could be propagated
back to the caller.
