Tony Lawrence b23cde9c5d DISK: Do not allow to emit any "footers"
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.

Open SIMH machine simulator

This is the codebase of SIMH, a framework and collection of computer system simulators.

SIMH was created by Bob Supnik, originally at Digital Equipment Corporation, and extended by contributions of many other people. It is now an open source project, licensed under an MIT open source license (see LICENSE.txt for the specific wording). The project gatekeepers are the members of the SIMH Steering Group. We welcome and encourage contributions from all. Contributions will be covered by the project license.

The Open SIMH code base was taken from a code base maintained by Mark Pizzolato as of 12 May 2022. From that point onward there is no connection between that source and the Open SIMH code base. A detailed listing of features as of that point may be found in SIMH-V4-status.
