QueryPerformance like function for both linux and windows.

[Gyiove]

Hello everyone!

I have been working with my game engine what must be run both in linux and windows and after trying to compile things on linux i discovered that i have to recode so many things.

I found most of the things yet QueryPerformance like function not.
I need this function to:
1. test the performance of my functions ( the time eclipse )
2. to calculate precise fps.

QueryPerformanceFrequency
QueryPerformanceCounter

Those are needed.
Thanks!
