+SQLite OS porting layer API.
+The behaviour of the RFile/RFile64::SetSize operation is not atomic for non-rugged drives.
+When RFile/RFile64::SetSize() is called 2 operations occurs:-
+1)The cluster chain of the file is updated.
+2)The new file size is added to the file cache.
+If a power loss occurs after a SetSize there is a chance that the cluster chain was updated

+This is most likely to occur in the journal file where the time between a SetSize and Flush can
+be long.
+For this reason this check is added when the file is opened to see if the end of the file can
+be read straight away, if an error is returned then it is assumed that the SetSize has not be
+completed previously. In this case the file is deleted and re-created.
