EXP: bind mount ruby and lxc for faster experiments

Before this patch, ruby and lxc were downloaded using apt-get,
which took some time (in addition to the time required for
doing an apt-get update). For a large number of containers (>4),
the time it took to install ruby and lxc on the containers was
too long.

This patch locates the various files needed by lxc and ruby on
the host's filesystem and bind mounts them into each container.
This way, network connection is not necessary to run the
experiments, and the container setup process is much faster.

This patch depends on the hosts's ruby interpreter being version
1.9.1. For other versions, the code to bind mount the ruby files
will need to be manually amended.
EXP: Fix some bugs and update to Raring

The scripts now run under Ubuntu 13.04 (Raring Ringtail) containers.
Additionally, there were some changes to the shared library files
that lxc uses, so those have been updated.

There were also some changes made to fix some bugs that occur when
run with Raring.
Update experiment scripts for Saucy
Added output of rk and pw
Update experiment parameters

Neither IP nor XIA can handle update rates above 10^5, so no tests
should be performed above that rate.

The update rate experiment is reworked to change with the destination
address as well.

64B packets cannot hold any destination addresses bigger than fb0 in
XIA, so no need to add those tests. Similarly, 128B packets cannot
hold the fb3 XIA destination address.
