Jonathan Druart a70980d825 Bug 17900: Fix possible SQL injection in patron cards template editing
To recreate:
/cgi-bin/koha/patroncards/edit-template.pl?op=edit&element_id=23%20and%201%3d2+union+all+select+1,user(),@@version+--%20

Look at the Profile dropdown list.

To fix this problem and to make sure it does not appears anywhere else
in the label and patroncards modules, I have refactored the way the
queries are built in C4::Creators::Lib
Now all of the subroutine takes a hashref in parameters with a 'fields'
and 'filters' parameters.
From these 2 parameters the new internal subroutine _build_query will
build the query and use placeholders.

Test plan:
1/ Make sure you do not recreate the vulnerability with this patch
applied.
2/ With decent data in the labels and patroncards modules, compare all
the different view (undef the New and Manage button groups) with and
without this patch applied.
=> You should not see any differences.

This vulnerability has been reported by MDSec.
