Gabe Black 6dd72cf55c systemc: Seperate out the sc_main fiber and its bookkeeping.
By pulling out the sc_main fiber (scMainFiber), we can make it
available to different entities in the simulator and avoid having to
have parallel bookkeeping.

Also this will make it possible to hook into sc_main without putting
the code in sc_main.cc.
