sys/osxvideo/: Fix leaks when running a NSApp.

Original commit message from CVS:
* sys/osxvideo/cocoawindow.h:
* sys/osxvideo/cocoawindow.m:
* sys/osxvideo/osxvideosink.h:
* sys/osxvideo/osxvideosink.m:
Fix leaks when running a NSApp.
Accept any kind of resolutions.
Works in fullscreen. Can maximize.
Only thing left before being able to move this to -good is documentation
and embedded window support.
