- limited to Quartz video output (OpenGL refuses to work in fullscreen mode)
        - controlled by opengl.c, which is linked to Carbon for this purpose
    - removed blocker from intf.m
    - introduced memory management to VLCEmbeddedList (!!!)
    - sanity checks for vout.m

* fix 'fullscreen only opens where my vout is, but I told it to open on another screen'. Remember that CGScreenID is different from VLC's 'video-device'

When you commit security fixes, please don't bundle them with feature extensions, and 
please *do* backport them yourself.

* reverting [23201], part 2, as current m4 files obviously are not compatible with older gettext releases (should have been part of [23368]
