databases/cego: update 2.35.8 -> 2.35.10

• Fix in CegoBufferpool::writeCheckpoint, in case of an locking exception ( lockBufferPool ), the pool must be released in any case. For this the CegoLockManager::lockBufferPool and CegoLockManager::unlockBufferPool have been modified in a way, that lockBufferPool saves the current sema index ( _poolRangeLock ) which is later used for the unlocking call.
• Timeout parameter for bufferpool lock reduced to 60 seconds.
• Optimization in CegoBufferPool:bufferfix for minHashId calculation in step 2, there was an unneeded locking operation for the minhashId, which was already locked by the main loop
• Small format fix in CegoProcCreateStmt ( missing indent )
• Add header row out put for client raw mode ( attribute names )
• Fix in CegoQueryHelper::evalPredicate, for all predicate types, the field array value has to be reset to 0, otherwise seg fault my occur since invalid references might be used
