Cocoa: Add autorelease pools.

A couple of cases where we call Cococa APIs without
having an autorelease pool in place surfaced after
removing the global autorelease pool in 1a218a7. 
(This happens when when Qt API is called before 
app.exec() has started the Cocoa event loop.)

Add local autorelease pools to prevent memory leaks.
