systemc: Add a simple implementation for sc_mempool.

This class is supposed to be a more efficient way to manage small bits
of memory. At least for now, new and delete will do the same job
functionally. Also, the heap manager may be just as efficient as
whatever custom mechanism sc_mempool would use.
