Makes the code much nicer to read. Default initialize cylinder_t to the empty cylinder. This produces lots of warnings, because most structure are now not PODs anymore and shouldn't be erased using memset(). These memset()s will be removed one-by-one and replaced by proper constructors. The whole ordeal made it necessary to add a constructor to struct event. To simplify things the whole optimization of the variable-size event names was removed. In upcoming commits this will be replaced by std::string anyway. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
