Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Stabilityfix: Do not trust lastDiveLogID == 0 at startup: If dive settings are reset for some reason also the lastDiveLogID is set to 0. Most likly the consostency check will find a valid entry. But this entry might not be the last one => return an error value to trigger the find function. Calling "find" at every startup is normal behavior if TRUST_LOG_CONSISTENCY is not set and was default for a long time => low risk In addition a check of the header adresses has been added to identify a potential error while writing log samples
