Adds support for passing short strings back and forth.
Simple illustrative example in test-mods/string_example. Ping-pongs a string 'hello' back and forth a few times. The string/data needs to be contained inside a single page for now. This should hopefully handle most of our immediate use cases. Idea: The sender grants the receiver access to the page that contains the data. The receiver maps it in their address space. This is clearly too slow for the main data path, and it's a bit hackie. But it works for strings that are passed in control plane interactions (rather than trying to cram the darn thing inside the message buffer). Wiki to be updated soon with more details.
