mmdevapi: Prevent 64 bit overflow within a few days of audio device use. (try 2)

[Joerg-Cyril.Hoehle at t-systems.com]

Hi,

The idea to replace X * numerator / denominator
by X / den * mul + remainder from euclidian division
came from
http://blog.airsource.co.uk/index.php/2010/03/15/quelle-heure-est-il/

M. Stefaniuc suggested an inline function. The MulDiv64 inline has the benefit
of ensuring unsigned arithmetic, matching GetPosition UINT64 output.
Why does MS QPC use a signed LARGE_INTEGER?!?

Regards,
 Jörg Höhle
