DISK: Do not allow to emit any "footers"

Browse source 
This is the initial iteration of cleaning up simh of appending the
"footers" to disk images:  it does not allow to emit any new "footers",
yet it does not change the behavior as to how any existing "footers"
are treated internally.  Also, even though sim_disk.c currently builds
the "footer" for any attached disk container, with this patch, it is
only kept in-memory, and never gets written to (appended / updated)
the actual container.
