Funcsim should be separated into two parts: functional core and scheduler

[GoogleCodeExporter]

As our funcsim will be a part of clock-precise simulator one day, it should be 
controllable by external entities. At the moment we start a simulation process 
with `void core::run()` method. This should be changed to the following scheme:

 * the main execution is run by `int core::run(int requested)' i.e. we specify that a core should execute no more than requested instructions, and it will return the amount of actually performed actions (which might be less). That is a functional core.
 * a separate object called scheduler is responsible of calling the core and of interacting with user. That is a scheduler
 * Functional core should provide interface that can be later used by clock-precise part. 

Thus, we'll be able to build two distinctive simulators on the same functioanl 
core - funcsim (core + sceduler) and clock-presise (core + clockl model).
