b25ea094d4 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.

8723b08dbf misc: Coupling gem5 with SystemC TLM2.0
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.
