Subject: 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.

+The program `raw', when run in `..' runs the program `run' produced
+from `meas.c'.  It produces a raw output file (see `../tmp/*.raw').
+`raw' will die with an error if run in the current directory.  Note
+that some versions of `time' produce output in an unexpected format;
+edit them by hand.
+
+`prim', `init', `cswap' and `go' produce formatted table entries used
+in the documentation (in `../doc').  For example, from `..',
+
+	foreach i (tmp/*.raw)
+	  time/prim $i
+	end
+
+See notes in the QuickThreads document about the applicability of
+these microbenchmark measurements -- in general, you can expect all
+QuickThreads operations to be a bit slower when used in a real
+application.
