Ordinarily, OVS switches back off when they can't reach their controllers.
Under the type of scenarios where Mininet is used, I think this is
probably just inconvenient.  This patch set controllers to attempt to
reconnect every second.

The previous version (12-05-16) does not compile on Ubuntu 12.10.

Also use a local variable to reduce duplication.

Fix method name mismatch for setDefaultRoute. 
This seems to be logically correct according to the intention of the code, but it may cause some trouble because routes will now be flushed by Mininet.configHosts().

Fixes #130

tiny fix to vm script

Conflicts:

	util/install.sh

closes #100

fixes #139

This should fix the problem of dump-flows not showing the OpenFlow
flow table flows and only showing cached kernel flow table flows.

Adjust numbering to support tc-based switch QoS

This looks fine to me - probably we want to change the way this works eventually, but for now renumbering it is fine and we can change the numbering later if desired.

both the reference switch and Open vSwitch assume ids with major 1
can be used for tc-based QoS

This may or may not be the right thing to do - an alternative
would be to ignore SIGINT, but that would make the popen()
job unkillable by normal means! So we'll try this and see
how well it works.
Fixes #124

In the future we may wish to enable moving interfaces across
nodes which are not in the root NS, and this would provide
the low-level mechanism to do so.
closes #122

Try invoking bash processes with -s mininet:host,
for easy identification of hosts. This enables
easy attachment using the util/m script.
closes #121

For local display, allow local root access
For remote display, tunnel with socat/mnexec
This should enable *wireshark in hosts* and fix #119

tools/install.sh: catch up oftest change
Looks fine to me.

Since oftest removed tools/munger directory, install.sh fails as follows
> mininet/util/install.sh: line 399: cd: tools/mnuger: No such file or directory
