epoll keyed wakeups: introduce new *_poll() wakeup macros
Introduce new wakeup macros that allow passing an event mask to the wakeup targets. They exactly mimic their non-_poll() counterpart, with the added event mask passing capability. I did add only the ones currently requested, avoiding the _nr() and _all() for the moment.
