Fixing copyright problems.

+

Callbacks, when the callback module is unknown (undefined), + results in warning messages.

+

A raise condition scenario. As part of a cancelation operation, + replies with waiting acknowledgements is cancelled. This includes + informing the user (via a call to the handle_trans_ack callback + function). It is possible that at this point the connection data + has been removed, which makes it impossible for megaco to + perform this operation, resulting in the warning message. The + solution is to also store the callback module with the other + reply information, to be used when cleaning up after a + cancelation.
