This is needed so that new processes (created with fork+exec) don't inherit open files, which can be important for a number of reasons. Since O_CLOEXEC is relatively new (POSIX.1-2008, before that Linux specific), we #define it to 0 in io.h to prevent compilation errors on older/crappy systems. At least this is the plan. input.c creates a pipe. For that, add a mp_set_cloexec() function (which is based on Weston's code in vo_wayland.c, but more correct). We could use pipe2() instead, but that is Linux specific. Technically, we have a race condition, but it won't matter.
