- Added patches for querycache.
The CegoQueryCache::addEntry method now is limited to
QUERYCACHE_MAXTRY tries to add an entry. Otherwise numFail
counter is increaed, which is monitored for the query cache.
This should resolve deadlocks in smoother way ( no more lock timeouts )
in case of other db thread have the requested querycache slot in use.
For performance reasons, CegoQueryCacheEntry::calcSize was introduced
to just calculate the entry size in the constructor.
- Added lockId for lock objects in CegoBufferPool and CegoQueryCache
