QCocoaEventDispatcherPrivate members should not be static

Browse Source 
Keep the Cocoa event dispatcher's private data as normal members of
QCocoaEventDispatcherPrivate. This removes the global initializers for
the macTimerHash and cocoaModalSessionStask as well.

To keep timers working, we pass a pointer to the timer's MacTimerInfo
struct to the callback, instead of just the timer id. The MacTimerInfo
needs to keep a pointer back to the QCocoaEventDispatcherPrivate to get
access to the private's members.
