c7b1c474c6
already a system macro under MacOS X.
* ./plugins/dummy/dummy.c: fixed vlc:loop, vlc:quit, etc. entries.
* ./plugins/glide/glide.c: activated double buffering.
* ./plugins/mga/xmga.c: started writing an xmga plugin; doesn't work yet.
* ./src/input/input.c: fixed the input memory leak, and the insane thread
spawning we got with vlc:loop.
* ./src/misc/intf_eject.c: disc ejection routine courtesy of Julien Blache,
currently Linux-only.
