Following situation: LibcURL in a qt event loop.

- register several easy handles within a multi one
- do a multi_perform
- read out the requested fd_set setup
- setup some QSocketNotifier event handlers for the requested fd events
(read,write,ex)
- in each event handler I can now do a multi perform again.

With the current state of the library, as I know it, I have to provide a
mapping

        [fd,type] ---> QSocketNotifier (type is read,write or exception)

since, when I see a change in the fd_set that is easily scanned of course I
need to find the Event handler to be shut down, so that the file descriptor
wouldn't stay in the internal qt select call.

If I had a close callback I could get rid of the fd_set scanning function and,
which is even more important I would get rid of the global [fd,type]->Handler
map.
