ETHER, PDP11, VAX: Added a built-in loopback agent which all ethernet devices can leverage to detect MAC address conflicts.
...
Some of this behavior was previously available in the pdp11_xq simulation for the DELQA device variants, but not the DEQNA. This adds the behavior for all ethernet devices.
The helps to avoid MAC address conflicts since the Ethernet physical address is completely user settable, and starts with a static value. Multiple simulators on the same LAN will have conflicting addresses if they don't specifically set unique values.

...
1. Treat the SBRM SysPOP like the BRM opcode for calling a subroutine.
2. If the -a (atomic) switch is present with a BRM or SBRM instruction, place a breakpoint at EA+1 rather than EA, since the return link is placed at EA (BRM) or at *EA (SBRM) with subroutine execution commencing at EA+1.

SDS: Clean up CPU modes and record CPU mode in instruction history record
...
The three CPU modes -- normal, monitor and user were represented by two binary flags (nml_mode and usr_mode). The code is simpler and easier to read if the three modes are represented by one three-valued variable, cpu_mode. In addition, record the CPU mode in the instruction history record, and add the mode to the history display.
In addition, add an optional flag to the SET CPU HISTORY=n command to *not* record instructions executed in a particular CPU mode. Flags are -n, -m and -u for normal, monitor and user mode respectively. For example, SET -m CPU HISTORY=n will only record instructions executed in normal or user mode, and will not record instructions executed in monitor mode. This change aids user-mode program debugging by not filling the history with monitor-mode service functions and interrupt activity.
