When keeping track of cylinder related data, the code was using static arrays of MAX_CYLINDERS length. If we want to use dynamically sized cylinder arrays, these have to be dynamically allocated. In C++ code, this is trivial: simply replace the C-style arrays by std::vector<>. Don't use QVector, as no reference counting or COW semantics are needed here. These are purely local and unshared arrays. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
