Use std::deque for DispatchEntry'ies.

Currently, there is a custom Queue class being used in InputDispatcher.
But that class makes a lot of assumptions about the memory management in
the queue. This also eliminates the possibility of using std::unique_ptr
inside dispatcher. First refactor to remove the custom Queue from
dispatcher.
