Updated mprpc/tamer version.
Added communications wrapper.
Added modcomm class to network. This wraps around an MPFD and
emulates the same interface. In addition, it allows a configurable
delay to be added inline to every communication across that MPFD.
Also, I added a puppet command to remotely set the delay per-process.
Puppet does not use modcomm--it executes commands directly and isn't
adversely affected by delay settings.
Also, I minimized some of the puppet chatter in the logging.
Finally, I added a simple delay test which demonstrates modcomm.
Merged modcomm and paxos_driver branches.
Note: we both wrote elect-me functions. I unified them.
I have not checked that the paxos functionality works. I only did
what looked best for the merge (which was to keep all your changes
except for the change from msgpack_fd's to modcomm_fd's).
