ext: Include SystemC 2.3.1 into gem5
In the past it happened several times that some changes in gem5 broke the SystemC coupling. Recently Accelera has changed the licence for SystemC from their own licence to Apache2.0, which is compatible with gem5. However, SystemC usually relies on the Boost library, but I was able to exchange the boost calls by c++11 alternatives. The recent SystemC version is placed into /ext and is integrated into gem5's build system. The goal is to integrate some SystemC tests for the CI in some following patches.

+Overview
+========
+
+This subfolder (/ext/systemc) is a custom redistribution of the Accellera
+SystemC 2.3.1 library [[1]][sysc]. This distribution replaces Accellera's
+Autoconf build system with a SCons build system, which is used by gem5.
+
+In the past it happened several times that some changes in gem5 broke the
+SystemC coupling. Recently Accelera has changed the licence for SystemC from
+their own licence to Apache2.0, which is compatible with gem5. However, SystemC
+usually relies on the Boost library. The repository contains all the source
+files from the Accellera distribution, but strips down the boost dependencies,
+shown here:[[3]][strip]. All references to the boost library are replaced by
+calls to the C++11 STL. This repository also contains the TLM 2.0
+protocol-checker from Doulos [[4]][doulos].
