odb: guard against data loss checking out a huge file
This introduces an additional guard for platforms where `unsigned long` and `size_t` are not of the same size. If the size of an object in the database would overflow `unsigned long`, instead we now exit with an error. A complete fix will have to update _many_ other functions throughout the codebase to use `size_t` instead of `unsigned long`. It will have to be implemented at some stage. This commit puts in a stop-gap for the time being.
