+ `routine.send` returns false when routine is not running
    + this will prevent panics sending to channels which have been
    closed
    + Make output channels routine specific removing the risk of someone
    writting to a channel which was closed by another touine.
    + consistency changes between the routines and the demuxer

    + ensure that we stop accepting messages once `stop` has been called
      to avoid the case in which we attempt to write to a channel which
      has already been closed

    + use `trySend` the replicate peer sending
    + expose `next()` as a chan of events as output
    + expose `final()` as a chan of error, for the final error
    + add `ready()` as chan struct when routine is ready

    + close `rdy` channel to ensure that calls to `<-ready()` will
    always return if the routine is ready

* cs: check for SkipTimeoutCommit or wait timeout in handleTxsAvailable

Previously, if create_empty_blocks was set to false, TM sometimes could
create 2 consecutive blocks without actually waiting for timeoutCommit
(1 sec. by default).
