MDL-27071 Allow Oracle IN() to use > 1000 items

of params (QM and NAMED supported) into a

Conflicts:

MDL-27071 Add big IN() unit tests

Let's verify how all databases perform with a big
number of parameters (10000) using IN() SQL clauses.
Both using QM and NAMED parameters.

Ideally only Oracle fails, and only it will need fixing.

MDL-39398 message: Prevent notice when sending Jabber messages

Not tracking the presence prevents a notice to be displayed during disconnect(),
where the the jabber server attempts to subscribe to $CFG->jabberusername presence.
As the server name does not include a resource identifier (stillwit@jabber.org/resource),
an explode('/') fails.
