vo_gl: add native mac osx Cocoa backend for vo_gl

Add native Cocoa code to display an OpenGL window. Some of the code is
based on the OpenGL parts of vo_corevideo but I took the time to remove
old code based on Carbon.

There is autodetection in the configure script but you can use
--enable[disable]-cocoa to enable[disable] this.
