The CXX config code is not entirely correct, and will fail with some of
the objects defined for systemc support. If you're going to build gem5
with --with-cxx-config, you have to also disable the systemc support.
This had been updated in the gem5_with_systemc/README file, but not in
the tlm/README file.

The SystemC TLM examples already include an example setup for elastic
traces. However, in the provided examples the L2 cache is omitted. This
patch provides an additionall example, which also includes an L2 cache
on the gem5 side.

* 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

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:
* Update the README
Updates for READMEs of /util/cxx_config, /util/systemc, /util/tlm.
Some minor corrections, mostly with respect to MAC/OSX

This patch adds an example configuration for elastic trace playing into the
SystemC world, similar to the already existing traffic generator example in
/util/tlm.

The CleanEvict command was not considered in /util/tlm/sc_port.cc this could
lead to a simulator crash. This issue is solved by ignoring this special
command type.

Transaction Level Modeling (TLM2.0) is widely used in industry for creating
virtual platforms (IEEE 1666 SystemC). This patch contains a standard compliant
implementation of an external gem5 port, that enables the usage of gem5 as a
TLM initiator component in SystemC based virtual platforms. Both TLM coding
paradigms loosely timed (b_transport) and aproximately timed (nb_transport) are
supported.
Compared to the original patch a TLM memory manager was added. Furthermore, the
transaction object was removed and for each TLM payload a PacketPointer that
points to the original gem5 packet is added as an TLM extension. For event
handling single events are now created.
