6629d9b2bc mem: use single BadAddr responder per system.
Previously there was one per bus, which caused some coherence problems
when more than one decided to respond.  Now there is just one on
the main memory bus.  The default bus responder on all other buses
is now the downstream cache's cpu_side port.  Caches no longer need
to do address range filtering; instead, we just have a simple flag
to prevent snoops from propagating to the I/O bus.

5f42bfcd56 process: separate stderr from stdout
- Add the option of redirecting stderr to a file. With the old
behaviour, stderr would follow stdout if stdout was to a file, but
stderr went to the host stderr if stdout went to the host stdout.  The
new default maintains stdout and stderr going to the host.  Now the
two can specify different files, but they will share a file descriptor
if the name of the files is the same.
- Add --output and --errout options to se.py to go with --input.

0ba2cc6571 Clean up config scripts to not have to worry about attaching a cache only to the TimingCPU. Now the Atomic CPU works with caches.
configs/common/Simulation.py:
    Atomic CPU now works properly with caches, so we don't have to do extra parsing to hook up caches only to the timing CPU.

    However the O3CPU must always use caches, so a check for that must still exist.

    Also change the switch_cpus to be placed at the system level, now that Steve changed how the IntrController gets its CPU.
configs/example/fs.py:
configs/example/se.py:
    Atomic CPU now handles caches.

049f8d53a9 make a lot of the same changes as to fs.py for checkpointing.
1) rearrange the options to be in a nice logical order
2) add an option for what i call "standard switch", which is from simple->timing->detailed
3) make checkpointing code such that checkpoints taken from the command line override checkpoint instructions compiled into binaries.
4) add an option for maximum number of checkpoints - simulation will stop at max or maxtick, whichever is first

40a04f2f40 changes regarding fs.py
1) rearrange the options to be in a nice logical order
2) add an option for what i call "standard switch", which is from simple->timing->detailed
3) change the client/server naming system to testsys/drivesys
4) make checkpointing code such that checkpoints taken from the command line override checkpoint instructions compiled into binaries.
5) add an option for maximum number of checkpoints - simulation will stop at max or maxtick, whichever is first

doesn't fully work because of a caching issue, but the python side of things i think should work - the counterpart of se.py does work.
i think i should factor out a lot of the common code in both, but i'll do that after this checkin, just to get this in the tree.
