2018-09-05	systemc: Implement sc_pause, sc_stop, and re-sc_start-ing.	Gabe Black
	This change further modifies the scheduler to implement the sc_pause and sc_stop functions, and to ensure that calling sc_start again works. Also, some small changes were made to how processes and contexts are hooked up. Now, rather than checking whether a process is running to determine wether it started on its own or needs to be started manually, there's a bool which explicitly tracks whether it needs this step. The problem was that once a thread finished, it wasn't considered running any more. In that case it had run but finished, but that was indistinguishable from it needing to run but not having been started.

2018-09-05	systemc: Partially implement the scheduler.	Gabe Black
	This change implements the "evaluate" part of the delta cycles, and sketches out a function to run delta cycles and the initialization phase. The kernel object now schedules an event at time zero which runs the initialization phase. Also, some small places which were stubbed out pending a way to check the currently running process have been filled in now that that's being tracked.
