cocoa_common: split the code, refactoring and cleanups

Split the code to several files. The GUI elements now each have they own files
and private state. The original code was a mess to respect the retarded mplayer
convention of having everything in a single file.

This commit also seems to fix the long running bug of artifacts showing
randomly when going fullscreen using nVidia GPUs.
