* Use one SConstruct to build everything instead of one SConstruct for

* Introduce SConscripts for sub-directories.
* Build in 'build' instead of the source tree.
* Build and link to SystemC from the ext/systemc directory. This

avoids possible issues caused by an incompatible SystemC build.
* Update the README and add some minor fixes

It seems like the m5 utility incorrectly called m5_loadsymbol instead
of m5_addsymbol. Judging by the signature of the loadsymbol command,
the expected behavior is to add a new symbol to gem5's symbol
table. This is behavior is implemented by m5_addsymbol.

The notion of forward dependencies is just expressing the same
dependency but at the other end of the dependency edge, i.e. at
the dependee rather than the depender. As there is no more
'power' here, it's strictly a convenience feature for handling
dependencies with tags that are not in the upstream repository.

This commit supports the use case of transitioning tags and their
associated checkpoint rewrites out of use for whatever reason. Just
replace the upgrader() method with a downgrader() method that performs
the appropriate inverse operation.
The tag name is still used, but only in this negative, 'zombie' state,
as it will be removed from the tags in the checkpoint and gem5 binary.

* Implement 'pipe through' for gem5 Packets (see explanation below)
Basically, this patch ensures that all transactions that originated in the
gem5 world are converted back to the original packet when entering the gem5
world. So far, this only worked for packets that are responded to by a
SyctemC component (e.g. when a gem5 CPU sends a request to a SystemC
memory). By implementing the 'pipe through' this patch ensures, that
packets that are responded to by a gem5 component (e.g. when a gem5 CPU
sends a request to a gem5 memory via a SystemC interconnect) are handled
properly.

sc_module, this patch does not break compatibility with existing code.

Python's header files set various compiler macros (e.g.,
_XOPEN_SOURCE) unconditionally. This triggers preprocessor warnings
that end up being treated as errors. The Python integration manual [1]
strongly recommends that Python.h is included before any system
header. The style guide used to mandate that Python.h is included
first in any file that needs it. This requirement was changed to
always include a source file's main header first, which ended up
triggering these errors.
This change updates the style checker to always include Python.h
before the main header file.

This patch is the eighth patch in a series adding RISC-V to gem5, and
third of the bonus patches to the original series of five. It adds some
regression tests to RISC-V.
Regression tests included:
- se/00.hello
- se/02.insttest (split into several binaries which are not included due
to large size)
The tests added to 00.insttest will need to be build manually; to
facilitate this, a Makefile is included. The required toolchain and
compiler (riscv64-unknown-elf-gcc) can be built from the riscv-tools
GitHub repository at https://github.com/riscv/riscv-tools.
Note that because EBREAK only makes sense when gdb is running or while in
FS mode, it is not included in the linux-rv64i insttest. ERET is not
included because it does not make sense in SE mode and, in fact, causes
a panic by design.
Note also that not every system call is tested in linux-rv64i; of the ones
defined in linux/process.hh, some have been given numbers but not
definitions for the toolchain, or are merely stubs that always return 0. Of
the ones that do work properly, only a subset are tested due to similar
functionality.

- unstylish modification of a file

- fix style, forgetting staging changes
- try to commit and fail, as although the changes staged are not

This patch avoids compiling ALPHA six times as part of running
'util/regress', and instead relis on NULL with different protocols to
run the rubytest. All we need is the memory system, so there is really
no need to compile the ISA over and over again.
The one downside is the removal of running 'hello' for the variuos
ALPHA and protocol combinations, but if this is a concern we should
rather beef up the synthetic tests for the variuos protocols.

This patch adds the ability for an application to request dist-gem5 to begin/
end synchronization using an m5 op. When toggling on sync, all nodes agree
on the next sync point based on the maximum of all nodes' ticks. CPUs are
suspended until the sync point to avoid sending network messages until sync has
been enabled. Toggling off sync acts like a global execution barrier, where
all CPUs are disabled until every node reaches the toggle off point. This
avoids tricky situations such as one node hitting a toggle off followed by a
toggle on before the other nodes hit the first toggle off.

Adds a wrapper to the fix functions of the verifiers. This wrapper first
copies the original file to a backup file, then performs the fix. If an
error occurs, the backup file is used to restore the original file.
Also fixed a line-length error in verifiers.py

In previous versions of systemC-gem5 coupling statistics were not updated
for the systemc-gem5 simulation. systemC-gem5 simulation only need the
previously built config.ini file and normal gem5 simulation has to be run
once to generate config.ini file. Thus stats.txt inside the m5out folder is
redundant for systemC-gem5 simulation. A new stats file is now generated
with the all the statistics for systemC-gem5 simulation. This will also
resolve the stats issue in tlm-sysmtemC simulation.
