Route fix

So, ignore the fact that it looks like shainerz is committing everything. Didn't change the name, oops. You can test route # (where # is a node you want the routing table from), and try it out. You have to pull libio and libcsp for all the code changes. Results at: https://gist.github.com/TheFlyingCouch/23c37cbf388f4246a575

@bryanyw 
It appears csp_transaction(_persistent) returns 0 upon timeout as well. I'd recommand checking status < 0 and reporting "timeout or other error". Note that if incoming length is wrong, there'll already be a printout warning, so you don't need to duplicate it.
