Stefano Pigozzi e70b5ee2fd cocoa_common: add HiDPI/retina support 
With a HiDPI screen, for performance and backwards compatibility
reasons, AppKit requests an OpenGL surface with a pixel number that
equals the user points number. After the image is rendered to this
smaller surface, it is upscaled so that its dimensions are comparable
across screens of different DPIs. The applied scaling is not that good
and makes the video/subtitles blurry; this is not acceptable for a
video player.

Request AppKit to use a high resolution OpenGL surface to back the
mplayer2 OpenGL view. Also set the window pixel size information
correctly in the VO object by converting user points to actual pixels.

All the system version checks are done at runtime so that the feature
is available on OSX 10.7 even with a binary compiled with older SDKs.

Also replace is_lion_or_better() with is_osx_version_at_least(10, 7, 0)
which is defined in osx_common.
