Christian Menard ccd9210e1a misc: Clean up and complete the gem5<->SystemC-TLM bridge [4/10]
The current TLM bridge only provides a Slave Port that allows the gem5
world to send request to the SystemC world. This patch series refractors
and cleans up the existing code, and adds a Master Port that allows the
SystemC world to send requests to the gem5 world.

This patch:
 * Move common code of the example to a common directory.  Move the cli
 * parsing from the SimControl module to a separate example object.  Add
 * comments describing the Gem5SimControl module.

Testing Done: Examples compile and run.
