This is the start of separating weston-the-compositor source files from libweston source files. This is moving all the files related to the 'weston' binary. Also the CMS and systemd plugins are moved. xwayland plugin is not moved, because it will be turned into a libweston feature. To avoid breaking the build, #includes for weston.h are fixed to use compositor/weston.h. This serves as a reminder that such files may need further attention: moving to the right directory, or maybe using the proper -I flags instead. v2: Move also screen-share.c, and add a note about weston-launch.
