buildsystem/cmake: Add an embryonary CMake support. Files are constrained into the buildsystem directory so you need to populate them prior using it, using:
cd vlc && sh ./extras/buildsystem/cmake/scripts/convert_vlc_to_cmake.sh

Move the Mac OS X framework plus the yet to be finished VLC.app to projects/macosx/framework and projects/macosx/vlc_app.

    projects/ - contains projects that link to libvlc other than vlc and the bindings.
    extras/package - contains the packaging specific files.
    extras/deprecated - deprecated files.
    extras/buildsystem - contains non-default buildsystem stuff.
    extras/analyser - contains code analyser (such as editor specific files) specific files.

vlc_threads_funcs.h: Don't attempt to track pthread_cond_wait() that takes a long time before returning as we usually idle that way. This removes annoying warning messages.
