The SystemC TLM examples already include an example setup for elastic

misc: Reorder sources in util/tlm and rewrite build scripts

* Use one SConstruct to build everything instead of one SConstruct for
each example.
* Introduce SConscripts for sub-directories.
* Build in 'build' instead of the source tree.
* Build and link to SystemC from the ext/systemc directory. This
ensures that SystemC does not need to be installed on the host and
avoids possible issues caused by an incompatible SystemC build.
* Update the README and add some minor fixes

---------------------------
misc: Clean up and complete the gem5<->SystemC-TLM bridge [5/10]

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:
* Introduce transactor modules that represent the gem5 ports in the
* SystemC world.
* Update the SimControl module and let it keep track of the gem5 ports.
