In some newer Linux distributions, env python default to Python 3.0. This
patch explicitly uses "python2" instead of just "python" for all scripts
that use #!

This patch fixes a few issues in the sweep scripts, bringing them
up-to-date with the latest memory configs and options.

This patch enhances the functionality of the DRAM sweep script to not
only plot the bandwidth utilisation, but also total power and power
efficiency. To do so, a command-line switch is added, and a bit more
data extracted from the stats.

This patch adds basic functionality to quickly visualise the output
from the DRAM efficiency script. There are some unfortunate hacks
needed to communicate the needed information from one script to the
other, and we fall back on (ab)using the simout to do this.
As part of this patch we also trim the efficiency sweep to stop at 512
bytes as this should be sufficient for all forseeable DRAMs.
