databases/cego: update 2.39.9 -> 2.39.11

• Improvements for log handling, the logIt method was moved from CegoTableManager to CegoBufferPool. This allows a more adequate locking of the logging actions. For this the tsLock array has been removed from CegoTableManager and lmLock array has been set up in CegoBufferPool. Since checkpoint writing occurs in CegoBufferPool ( which is also relevant for loging operations ), the logging method is now part of CegoBufferPool.
• The logAction method in CegoLogManager has also been improved in a way, that a log buffer is not allocated for each logging operation anymore. Instead, a logBuf array has been defined for all tablesets and the logBuf is reallocated, if the current logging record exceeds the log buffer.
