Move waiting/signaling to the backends so we can fix each backend separately. As I write this patch the vm_bind backend is back to using synchronous vm_binds so we can't pass syncobjs to the synchronous vm_bind ioctl anymore. We'll need more discussions and possibly some rework before we go back to asynchronous vm_binds. This commit should allow us to fix the TR-TT backend in the next commit and leave vm_bind for later.
