Revise platform APIs to use LastErrorException about jna HOT 2 CLOSED

If I understand correctly what this means, ie. that any Win32 call that fails should throw, it would hinder programmer sanity in how the Win32 API is used. It would also break a ton of existing code.

In Win32 you typically call an API once, get an error and then use the result to do something. If you make Win32 functions throw by default, most of the using code will become a set of interconnected try/catch/finally with lots of flow mistakes, leaks, etc. As an API wrapper JNA shouldn't be deciding to transform an HRESULT into an Exception every time IMO, these Win32 functions return something called an HRESULT, sometimes, further interpretation is a matter of preference.

Nice idea in theory, probably not so much in practice. Easy enough to make ad-hoc definitions where it matters.
