Luboš Luňák 1946794ae0 mass removal of rtl:: prefixes for O(U)String*
Modules sal, salhelper, cppu, cppuhelper, codemaker (selectively) and odk
have kept them, in order not to break external API (the automatic using declaration
is LO-internal).

<p>The notified new <type>XResultSet</type> will stay valid after returning
notification. The old one will become invalid after returning notification.
<p>While in notify-call the listener is allowed to read old and new version,
except in the first call, where only the new Resultset is valid.
<p>The Listener is allowed to blockade this call, until he really want to go
to the new version. The only situation, where the listener has to return the
update call at once is, while he disposes his broadcaster or while he is
removing himsef as listener (otherwise you deadlock)!!!
