databases/cego: 2.35.10 -> 2.36.0

• Completed pointer cleanup in CegoQueryHelper::evalPredicate, added check061 to check pointer cleanup
• Fix in CegoTableManager::createBTree, pC object cursor has to be set to 0, otherwise in case of abortion a seg fault occurs
• Changed default value for btree cache enabling to false
• Improvement in CegoBufferPool::calcSegment for segid calculation. It has been recognized, that with the current calculation ( pageid % numsegment ) not all slots can be reached for special buffer pool configurations. The formula has been changed ( to ( pageid / numpages ) % numsegment )
• Adding missing export / import messages to CegoXPorter
• Changed btree cache enabling syntax. Instead of a dedicated switch command ( set btree cache on / off ), the cache option now is directly given with the create btree command ( e.g. create btree b1 on t1(a) cached )
