Add a new class SolarMutexClearbleGuard

Browse source 
Few place in the code use vos::OClearbleGuard aGuard(Application::GetSolarMutex());
or something similar.
This new class hide this ugliness into
SolarMutexClearableGuard aGuard;

This also has the merit to push down the vos:: dependency down into one location
for this kind of access, which will simplify the vos dependency removal.
