This change makes all C++-based tools in tools/ abort when they
encounter an unknown commandline parameter (both option or
non-option). This has already caused some confusion, as in some cases
unexpected behaviour can be the result. For example, "prune-trace -t
mytrace.tc -d database" up to now ignored the "-t" parameter, took
"mytrace.tc" as the first non-option parameter (and ignored it); as no
option parameter may follow the non-option parameters, all other
options were ignored as well.

As these tools work closely together with fail components, its
easiest, to build them in this context. As these tools don't
really matter for fail use, they might never be pushed to the
master branch.
