misc: Clean up and complete the gem5<->SystemC-TLM bridge [1/10]

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:
 * Restructure the existing sources in preparation of the addition of the
 * new
   Master Port.
 * Refractor names to allow for distinction of the slave and master port.
 * Replace the Makefile by a SConstruct.

Testing Done: The examples provided in util/tlm (now
util/tlm/examples/slave_port) still compile and run error free.
