Make it possible to use sample-exact controls in LADSPA plugins

Browse Source 
I don't think we currently have any that would support this functionality, but in case someone has a LADSPA plugin that has audiorate control ports, this allows them to be used with the new sample-exact models
Again... not strictly related to memory management, but since I was in that part of the codebase already...
