EXP: allow packet sizes greater than 1500B

For experiments that test packet sizes of greater than 1500 bytes,
the MTUs of the devices (eth0 for every container, bridge to every
container, and veth for every container) are changed to the packet
size to be tested.

This information is printed to the experiment log.
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.
