mqueue and bpf go through rather painful and similar contortions to
create objects in their dentry trees. Provide a primitive for doing that
without abusing ->mknod(), switch bpf and mqueue to it.
Another mqueue-related thing that has ended up in that branch is
on-demand creation of internal mount (based upon the work of Giuseppe Scrivano).
