spot/twaalgos/product.cc, spot/twaalgos/product.hh: Use an
output_aborter argument to abort if the output is too large.
* bin/ltlcross.cc: Use complement() with an output_aborter
so that ltlcross will not attempt to build complement larger
than 500 states or 5000 edges.  Add --determinize-max-states
and --determinize-max-edges options.

* NEWS: Document this.
* bin/spot-x.cc: Add documentation for postprocessor's
det-max-states and det-max-edges arguments.
* doc/org/ltlcross.org: Update description.
