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.

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.

cocoa: redo synchronization Before this change, Cocoa state was accessed from both the VO and the Cocoa main thread. This was probably not a good idea. There was some locking as well as implicit synchronization using the dispatch mechanism, but it wasn't watertight. Change this completely. Now Cocoa things are always accessed from the main thread only. The old mutex falls away, as well as the vo_cocoa_set_current_context() function, which implicitly used the lock to coordinate VO accesses. With the new code, the VO thread generally has to wait for the main thread, while the main thread never waits for the VO and rarely accesses it. Fortunately, this is rather straight forward, and most of this is achieved by making vo_cocoa_control() run on the main thread. The logic of the code does generally not change. Some aspects are trickier. Apparently we can't access the NSOpenGLContext from the VO thread, because this object is not thread- safe. We use some CGLContextObj functions instead, such as for making the context current and swapping the buffers.

video/out: introduce vo_control for gl_common based VOs Instead of having separate callbacks for each backend-handled feature (like MPGLContext.fullscreen, MPGLContext.border, etc.), pass the VOCTRL responsible for this directly to the backend. This allows removing a bunch of callbacks, that currently must be set even for optional/lesser features (like VOCTRL_BORDER). This requires changes to all VOs using gl_common, as well as all backends that support gl_common. Also introduce VOCTRL_CHECK_EVENTS. vo.check_events is now optional. VO backends can use VOCTRL_CHECK_EVENTS instead to implementing check_events. This has the advantage that the event handling code in VOs doesn't have to be duplicated if vo_control() is used.
