Bug 15581: Add a circ rule to limit the auto renewals given a delay

This patch adds a new circulation rule (no_auto_renewal_after) to block/allow
auto renewals after a given delay.
For instance, if the issue date is 10 days before today, and
no_auto_renewal_after is set to 10, tomorrow the issue won't be auto
renewed.

Test plan:
0/ Execute the update DB entry
Note: You will have to manually change data in your DB, make sure you
have access to the sql cli.
1/ Define a rule with no_auto_renewal_after (10 for instance) and
norenewalbefore (5 for instance).
(This new rule will behave the same as norenewalbefore: the unit depends
on the lengthunit value).
The automatic renewals will be done from 5 to 10 days ahead.
2/ Modify the issues.issuedate, to simulate a checkout in the past:
    UPDATE issues
    SET issuedate = "yyyy-mm-dd hh:mm:ss"
    WHERE itemnumber = YOUR_ITEMNUMBER;
with issuedate = 2 days before for instance
3/ Execute the automatic renewals cronjob script (misc/cronjobs/automatic_renewals.pl)
Confirm that the issue has not been renewed (too soon)
4/ Repeat step 2 with a due date set as 11 days before
5/ Execute the automatic renewals cronjob script (misc/cronjobs/automatic_renewals.pl)
Confirm that the issue has not been renewed (too late)
6/ Repeat step 2 with a due date set as 7 days before
7/ Execute the automatic renewals cronjob script (misc/cronjobs/automatic_renewals.pl)
Confirm that the issue has been renewed (issues.renewals has been
incremented and date_due has been updated according your circ rules).
