We now automatically reopen the pty when the child process died. This will
most-often simply restart the shell or login program.

Other registered callbacks might get confused if we change the parameters.
Hence, we use a static copy for further actions.

We might have missed a display when our handler was not registered, yet.
So enumerate these displays on wakeup so we can be sure that we have all
displays registered with the terminal subsystem.

A symbol table should never be created twice therefore we can make it
static and global. We add locks so it is totally thread-safe, too.

We now use the new input/video hooks to avoid waking up the UI all the
time. This reduces the code in the generic UI subsystem and makes the
terminal handle all the stuff.

When deleting a hook we should not search for the callback only. Otherwise
we might remove the wrong callback. Therefore, we now search for callback
and data argument. If multiple callbacks are registered with the same data
and cb, then we don't care which one is removed as this wouldn't make any
difference. They behave the same way, anyway.
