In some cases the write-pilot is located at the upper boundary of the
experiment and thus is in a race situation with the experiment's end.
If the experiment's end occurs first, the campaign ends and complains
about missing data, otherwise everything is fine.
This patch circumvents this via using "the first" writing pilot; iff the
only write is located at the experiment's end, the race will still occur,
but cleverly written experiment code can, according to hsc, circumvent it.

Up until now the JobServer was silently losing jobs and only claiming to be
finished - a workaround for this was to restart the campaign until all jobs
were finished according to the database and the campaign's output.
This change fixes the underlying problem, so a single campaign-run suffices
and does no longer lose any jobs.
Debugging this was awful and took us quite some time...

This removes the ability to directly parse protobufs from the socket, because
google::protobuf::Message::ParseFromFileDescriptor() needs a EOF after each message;
thus preventing us from sending multiple Message objects over a single socket.

"removed" unneccessary memory-mapping ("Step 0")
cleaned out ExperimentData - now consists only of fsppilot and resultset
resultset now contains bitoffset which is part of result-table's primary key
adapted code to work with msg.fsppilot() instead of ExperimentData-values
