Description

LocalInputChannel#getNextBuffer de-serialises all incoming events on the lookout for an EndOfPartitionEvent.
Some buffer code de-serialises all incoming events on the lookout for an EndOfPartitionEvent
(now applies to PartitionRequestQueue#isEndOfPartitionEvent()).

Instead, if EventSerializer offered a function to check for an event type only without de-serialising the whole event, we could save some resources.
