Index and BLOBs garbage collection doesn't work for update_in_place()
---------------------------------------------------------------------

                 Key: CORE-4383
                 URL: http://tracker.firebirdsql.org/browse/CORE-4383
             Project: Firebird Core
          Issue Type: Bug
          Components: Engine
    Affects Versions: 3.0 Alpha 2
            Reporter: Dimitry Sibiryakov


Following script leaves orphan nodes in index even if CORE-4382 is fixed 
because jrd_tra uses static buffer for undo data.

create database "g_test";
create table g_test (f integer);
create index g_ind on g_test (f);
insert into g_test values (1);
commit;
update g_test set f=2;
savepoint a;
update g_test set f=3;
savepoint b;
update g_test set f=4;
savepoint c;
update g_test set f=5;
savepoint d;
update g_test set f=6;
savepoint e;
update g_test set f=7;
commit;
select * from g_test;
