Making use of the C++ structures in C only code feature introduced with

r34441. This allows to completely stick to FreeBSD's conditional cv_* function
semantics as 'struct cv' variables are freed automatically now.
This also gets rid of the dynamically de-/allocating of ConditionalVariables.
Thank you Ingo for helping me through this.
