In order to improve performance in the serial modules and add DB constraints,
this patch is going to add missing foreign key on the following columns:
* serial.biblionumber
* serial.subscription
* subscriptionhistory.biblionumber
* subscriptionhistory.subscriptionid
* subscription.biblionumber
Once done, some code can be removed from the Del* subroutines, as the ON
CASCASE clause will make the RDBMS handles the deletions.
Test plan:
0/ It would be useful to test the update DB entry on a big and old
production DB, to make sure the constraints will be added correctly.
We could remove the entries before creating the constraints, but it can
be unecessary
1/ Make sure you can recreate a fresh install with the kohastructure.sql
from this patch
2/ Make sure you can upgrade from a master install
3/ Create a subscription, serial, etc. and delete the biblio
=> The subscription/serials should have been deleted from the DB
4/ Create a subscription, serial, etc. and delete the subscription
=> The serials should have been deleted from the DB
