ubik: improve logging for database synchonizations
As an aid for debugging database synchronization issues, ensure that the
logging is consistent and unambiguous for both the client and server
sides of DISK_GetFile and DISK_SendFile. Add new error messages as
required.
In addition, rework the "recovery sending version to <IP>" message in
urecovery_Interact. This message is misleading because the new version
database is only sent to a DB server if its version is not up to date.
Instead, move this message into the version check block immediately
below it. Also reword it for clarity and promote its log level from 5
to 0. Finally, remove the now-superfluous "recovery stating local
database" log message.
