back-sql: change ORDER BY clause in backsql_get_attr_vals()

[maestro <maestro82@gmail.com>]

Hello all!

i have a very weired DB i need to access with back-sql.
the DB does only support identifiers of max 18 chars length so i had to
change the back-sql code to rename the ldap_entry_objclasses to
something shorter - that is solved 

but this DB also cannot ORDER BY <alias> - since all
backsql_get_attr_vals calls seem to only request one column it seems
save to hardcode to ORDER BY 1 instead. i'm just wondering where the
best place would be to do so 

any help is very appreciated.

cheers
m.
