clone-prepare-to-recycle-clone_detached-and-clone_stopped
Ulrich says that we never used these clone flags and that nothing should be
using them.
As we're down to only a single bit left in clone's flags argument, let's add a
warning to check that no userspace is actually using these. Hopefully we will
be able to recycle them.
Roland said:
CLONE_STOPPED was previously used by some NTPL versions when under
thread_db (i.e. only when being actively debugged by gdb), but not for a
long time now, and it never worked reliably when it was used. Removing it
seems fine to me.
