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.

+Installation of the `QuickThreads' threads-building toolkit.
+
+* Notice
+
+QuickThreads -- Threads-building toolkit.
+Copyright (c) 1993 by David Keppel

+Permission to use, copy, modify and distribute this software and
+its documentation for any purpose and without fee is hereby
+granted, provided that the above copyright notice and this notice
+appear in all copies.  This software is provided as a
+proof-of-concept and for demonstration purposes; there is no
+representation about the suitability of this software for any
+purpose.
+
+
+* Configuration
+
+Configure with
+
+	./config *machtype*
+
+where "*machtype*" is one of the supported target machines.  As of
+October 1994, the supported machines (targets) are:
+
+	axp --	All Digital Equipment Corporation AXP (DEC Alpha)
+		processors, compile with GNU CC
+	axp-osf1 -- AXP running OSF 1.x
+	axp-osf2 -- AXP running OSF 2.x
+	hppa -- HP's PA-RISC 1.1 processor
+	hppa-cnx-spp -- Convex SPP (PA-RISC 1.1 processor)
+	iX86 --	80386, 80486, and 80586-compatible processors
+		See notes below for OS/2.
+	iX86-ss -- 'iX86 for assemblers that use slash-slash ('//')
+		comments.
+	ksr1 --	All KSR processors
+	m88k --	All members of the Motorola 88000 family
+	mips --	MIPS R2000 and R3000 processors
+	mips-irix5 -- Irix 5.xx (use `mips' for Irix 4.xx)
+	sparc-os1 -- V8-compliant SPARC processors using compilers
+		that prefix labels (e.g. "foo" appears as "_foo")
+		Includes Solaris 1 (SunOS 4.X).
+	sparc-os2 -- V8-compliant SPARC processors using compilers
+		that do not prefix labels.  Includes Solaris 2.
+	vax --	All VAX processors
+
+In addition, the target `clean' will deconfigure QuickThreads.
+
+Note that a given machine target may not work on all instances of that
+machine because e.g., the assembler syntax varies from machine to
+machine.
+
+Note also that additions to a processor family may require a new
+target.  So, for example, the `vax' target might not work for all
+future VAX processors if, say, new VAX processors are introduced and
+they use separate floating-point registers.
+
+For OS/2, change `ranlib' to `ar -s', `configure' to `configure.cmd'
+(or was that `config' to `config.cmd'?), and replace the soft links
+(`ln -s') with plain copies.
+
+
+* Build
+
+To build the QuickThreads library, first configure (see above) then
+type `make libqt.a' in the top-level directory.
+
+To build the demonstration threads package, SimpleThreads, type
+`make libstp.a' in the top-level directory.
+
+To build an executable ``stress-test'' and measurement program, type
+`make run' in the top-level directory.  Run `time/raw' to run the
+stress tests.
+
+
+* Installation
+
+Build the QuickThreads library (see above) and then copy `libqt.a' to
+the installation library directory (e.g., /usr/local/lib) and `qt.h'
+and `qtmd.h' to the installation include directory (e.g.,
+/usr/local/include).
