Also, added some output formats that Core Audio ought to be able to handle.

wodSendNotifyInputCompletionsMessage sends the kWaveInNotifyCompletionsMessage
to the message thread, which calls widHelper_NotifyCompletions.

It scans for completed input wavehdrs, removes them from the queue,
and notifies the application that they're done.

It now returns in an output parameter the frame count that the AU will use.
Also, initialize the Audio Unit.

It will serve as the input callback called when our Audio Unit has sound
data available.

With grateful acknowledgement to Marcus Meissner.

This reverts commit 045975b1.

The tests show the behaviour when the IROTData interface is not
available from the moniker. They also show the flags that are accepted
into IRunningObjectTable::Register.

ole32: Contrary to MSDN, IROTData doesn't need to be implemented for a moniker to be usable with the running object table.

If IROTData isn't available, fall back to a path that uses the display 
name and the clsid of the moniker to generate the comparison data.

ole32: Use IMoniker::GetTimeOfLastChange to attempt to retrieve the last-modified time for the ROT entry.

However, fall back to CoFileTimeNow if it fails.

ole32: Execute Reduce using the moniker's vtable in CreateCompositeMoniker as the moniker isn't necessarily a composite moniker.

ole32: ROTFLAGS_REGISTRATIONKEEPSALIVE and ROTFLAGS_ALLOWANYCLIENT are legal to be used together in RunningObjectTable_Register.
