Register a callback interface (and a callback handle argument) to be
called to enable a receiver to set the registration ID it uses for a
given source (UME only).

C# |
public void setRegistrationIdCallback( LBMRegistrationIdCallback cb, Object cbArg )

- cb (LBMRegistrationIdCallback)
- An object implementing the LBMRegistrationIdCallback delegate interface
- cbArg (Object)
- Callback object passed as a token to the callback interface

This callback is called directly in line and does not use the event queue;
therefore, the callback function used should not block or it will block the
context thread processing.
This API may not be called from a wildcard receiver create callback.
Doing so will not result in the callbacks being called.
