[PATCH] Fix CTDB event handling issues (bug #13659)

There are several issues:

* eventd leaks a pipe file descriptor into long-lived children,
  breaking ctdbd's ability to know if eventd goes away

* ctdbd goes into a broken state if eventd goes away

* When ctdbd says it is refusing to run an event during recovery,
  the event is run anyway

* There is a valgrind hit in packet construction

All are in 4.9, the first 3 are in 4.8 too.

Patches for the file descriptor leak are by Amitay and are already
reviewed by me.

Please review and maybe push...

peace & happiness,
