SCTP: refactoring
This patch takes care of some refactoring, including the initialization
of the timestamp to calculate the RTO, the output state-machine
validation which can be enabled (disabled by default) when debugging and
some clean-up of unused fields.
It also addresses the requirement of Karn's algorithm when computing the
RTO.
