Patch to create experiments9

As the port 922 is filtered by my ISP in vacation, I directly provide the
commit as a patch here.

This is very preliminary work. The router do not complete yet, it reaches
only 99.9%. The coriolis2/settings.py contains some parameters variations
to tweak the router and compare the different outcomes. I will use it to
find geomtric cases where the router takes bad decisions and correct them.

A note about nMigen and a potential annoying bug at installation. nMigen
is listed as a dependency so setup tools will try to install it.
But if it is not installed *prior* to the Libre-SOC repositories, the
m-lab version will be pulled from the Python archives. Which is not
what we need. And if you don't install in system directories, like I
do, you even get two versions... One good and one bad...
