From 3d3e50beaf534ec30b151614f684eccd85ef5782 Mon Sep 17 00:00:00 2001
From: des <des@FreeBSD.org>

Subject: Add a pn_destroy field to pfs_node.  This field points to a
 destructor function which is called from pfs_destroy() before the node is
 reclaimed.

Modify pfs_create_{dir,file,link}() to accept a pointer to a destructor
function in addition to the usual attr / fill / vis pointers.

This breaks both the programming and binary interfaces between pseudofs
and its consumers.  It is believed that there are no pseudofs consumers
outside the source tree, so that the impact of this change is minimal.
