deadlock in IGMP streaming server when switching live TV. Previously cComponentIGMP::Accept did all the work including the channel switch with the new cConnectionIGMP waiting for MainThreadHook. But as the new connection is stored *after* Accept, MainThreadHook didn't see it and so wasn't able to switch. The streamdev main thread waited forever. Moved the main work into cComponentIGMP::Welcome.
