[ticket/10875] Remove useless assignment from phpbb_cache_driver_memory.

sql_save() no longer takes $query_result as a reference, thus this assignment
is a no-op.

[ticket/10875] Fix logic in phpbb_cache_driver_file::sql_save().

Previously (develop-olympus) $query_result was passed via reference into

Adjust logic to take this change into account correctly.

[ticket/11209] Clone disable moving images to allow multiple per page

The disable images need to be clone rather then moved, in order to allow
multiple disable images per page. We do not have such a case at the moment
but it will be required for the new teampage/legend ACP section.

[ticket/11219] Update sequence values after loading fixtures

If a value is provide for an auto_increment type of column, certain DBMSes
do not update their internal sequencers. If a row is inserted later, it can
be given an ID that is already in use, resulting in an error. The database
test cases now resynchronise the sequencers before the tests are run.

[ticket/11219] Recreate Oracle sequences instead of altering them

The previous method would always leave a gap between the last value and the
new one due to how you have to update the sequence values. To remove gaps in
all situations, the options are to alter the USER_SEQUENCES table or just
drop the sequence and recreate it. The prior requires elevated priveleges
and the latter can break attached objects. Since we don't attach objects to
the sequences, we won't have any problems doing it for the tests.
