Today the file descriptor for the access of the event channel driver is being closed in case of exec(2). For the support of live update of a daemon using libxenevtchn this can be problematic, so add a way to keep that file descriptor open. Add support of a flag XENEVTCHN_NO_CLOEXEC for xenevtchn_open() which will result in _not_ setting O_CLOEXEC when opening the event channel driver node. The caller can then obtain the file descriptor via xenevtchn_fd(). Add an alternative open function xenevtchn_fdopen() which takes that file descriptor as an additional parameter. This allows to allocate a xenevtchn_handle and to associate it with that file descriptor.
