3ec3e3aa8f AltairZ80: Fix HALT stop code conflict with ON ERROR 
AltairZ80 uses 0 for the VM-specific HLT instruction stop code.
SCP defines SCPE_OK as 0.
SCP uses 0 to mean all errors ("ON ERROR").

The command "ON 0" will generate "%SIM-ERROR: Invalid argument: 0".

This PR changes the HALT stop code from 0 to 5.

e91fbebe3d AltairZ80: i86: Don't clear segment override on REPE/REPNE 
MASM generates REP CS:MOVSW as:

REP
CS:
MOVSW

The Seattle Computer Products 8086 assembler allows the segment override
as a discrete opcode.  This means that:

CS:
REP
MOVSW

is also possible, and in fact used in the SCP Monitor v1.6.

The i86 emulator was clearing the override flags when REPE/REPNE,
is encountered, which causes the segment override to be lost.
Verifying the behavior of a real 80286 processor in an IBM PC/AT
(5170) using MS-DOS 6.22 DEBUG shows that both instruction sequences
yield the desired segment override.

Fix AltairZ80 compilation with Visual Studio 2008 (#85) 
* AltairZ80: SS1: Fix disable after reset.

The CompuPro System Support 1 could not be disabled after enabled and
used due to timers causing it to be busy.  Reset properly so that "set
ss1 disabled" works after reset.

* AltairZ80: wd179x: Properly reset 179x state.

* AltairZ80: M68K: Fix compile with VS2008.

* Musashi: Fix compilation with Visual Studio 2008.

6c72231177 AltairZ80: Add MDS-AD support for single-density 
The North Star MDS-AD disk controller supports both single- and
double-density operation.  While mixed-density is supported by the
controller, it is not supported by AltairZ80 due to a limitation of the
.nsi image file format.  The .nsi image file format requires all sectors
to be of the same density.

f0dd8184d8 AltairZ80: Fix North Star MDS-AD for NSDOS 
The "Window" bit was getting cleared too late, causing the "next" sector
to be written under North Star DOS.  Due to differences between CP/M and
North Star disk access routines, this was not an issue under CP/M.

Test: Verify that North Star DOS and CP/M can format, copy and verify an
entire disk.
