Revision: 8078
Log message:
Added most of the code for the consensus protocol. Also got the
code for the flooder test program to compile and in the meanwhile
fixed a bug in the OMakefile for libmojave.
What we miss right now is the code for processing the replies sent
when the consensus is done. Timeouts need to be added too.

Revision: 8083
Log message:
Fixed a few problems with the code. Updated the OMakefile to
include $(LIBMOJAVE_HOME) in .SUBDIRS.
One of the issues we have is that ControlMsgs don't have a group
sequence number, which makes it impossible to acknowledge them
through the standard procedure.
I still need to add timeouts. I spent a LOT of time trying to find a
stupid Marshalling/Unmarshalling bug.

Revision: 8086
Log message:
Added a portion of the timeout implementation for the view change protocol. It is not quite done yet, but it is close. What is remaining is the proper setting (and clearing) of the timers in all the relevant locations.

Finished adding the timout code for the view change stages. It still needs to be tested, but at least everything should be in there.

Log message:
The code for the consensus algorithm is in place. I still need to add
timers for timeouts, but I'll do it in the morning.

Revision: 8113
Log message:
The code works as expected for two nodes, including timeouts, failure
detection and consensus.
We had a few nasty bugs that would depend on a particular interleaving of
messages that were hard to debug but now they are fixed.
We need to take out the output and try to get some benchmarks. We also have
to tweak the timeouts and the time we hold on to the token to be able to
get good results.

Revision: 8131
Log message:
A number of changes were made to make the implementation more true to the spin/TLA models. In particular, some of the sections dealing with the postponed_joins were reworked. For the most part, things are now working as expected for 3 nodes.
One problem remaining, however, is that sometimes the consensus reply_ack_timer is being started when it is already running.
