31e7a7f3e0 PDP11 & Unibus/Qbus VAXen: Detect devices missing addresses before boot 
If autoconfigure is disabled, either explicitly or implicitly by manual
setting of an ADDRESS or VECTOR, detect devices which don't have
addresses before boot.

d6ebe32b30 PDP11 & Unibus/Qbus VAXen: Document autoconfigure disabling 
Historically, if a configuration file explicitly set either a DEVICE's
ADDRESS or VECTOR, autoconfiguration was immediately disabled.

This change defers disabling autoconfigure until an explicitly setting
of a DEVICE address or VECTOR actually changes what had been previously
configured by autoconfigure.

ac73e7b4c7 Unibus and Qbus VAXen: Add DUP-11/DPV-11 device 
These devices start disabled and will be that way in essentially all
working systems, but there apparently was a DECnet Phase V
support for this device, so it is added to all systems. The DPV
should now be readily testable.

As mentioned in #1152.  That PR will fix the DUP device.

ae1472db79 Generated ROM Image includes: Updated for multiple ROM image support

created arrays are unchanged.

Multiple ROM image include files can be included in the same source module
without the need for any #undef BOOT_CODE_SIZE, etc.

a015e44c10 ALL: Standardize writelock behavior adding global UNIT_WLK & UNIT_WPRT 
Historically this functionality was reimplemented within each
DEVICE simulator often with slightly different implementations
and inconsistencies.  Solving this globally within SCP required
changes in many places, but should henceforth be reasonably
managed.

a10b8969cd MicroVAX2000, VAXStation2000: Properly describe 16MB of memory in CFGTST reg 
The CFGTST register MTYPE subfield should describe the additional memory
beyond 2MB on the processor board.  Previous logic attempted to describe
the total system memory and the net result didn't fit into the 3 bit field and
thus said no additional memory is present.

The consequence of this new amount of memory is that ALL of it is tested
during the power on self test and thus it takes significantly longer to get to
the >>> prompt.

4db4f90429 VAX, Unibus VAX: Record explicit TODR set immediately to backing store 
- Only if backing store is used (i.e. OS Agnostic mode)
- Previously this was only done on a clean simulator exit.  That could
  result in inconsistent timing information in operating system images vs
  the saved TODR baseline data
- Always return TODR values rounded to the TODR granularity (10ms).

ae825c9afb All: Declare sim_stop_messages as an array SCPE_BASE long 
This avoids a potential invalid pointer dereference when formatting
the return value from sim_instr() if it is < SCPE_BASE but greater
than the previously defined static array size.sizeof

Update simh.doc to reflect this generic change.
