Handle no devices and no platforms better
- Properly catch the exception thrown by getDevices() and if it's a no
devices found error just return an empty vector.
- Replace C macro for getPlatforms() with a proper function

Quick discovery of optimal global work size
Use a dichotomic algo to discover optimal m_globalWorkSize:
- m_wayWorkSizeAdjust is the direction steps are done (-1 or +1)
- m_stepWorkSizeAdjust is the steps of adjustment (added or substracted
to m_globalWorkSize)
- when a change of direction is needed, step is divided by 2

Restore the old default value of global work size
It used to be 64 (local size) * 4096 (global multiplier). Miners
reported a lot better results with those old defaults and as such we are
bringing them back.

as a multiplier of the local work size.
