49eccc768a SCP: Include all simh supported system includes in sim_defs.h 
Only SCP libraries should be including additional OS specific include
files since they cover both:
   1) Are responsible for platform specific details integrated into simh
       support
and
   2) Implement extended functionality optimally considering the proper
       behaviors to cooperate with the simh event system and existing
       capabilities.

Simulator code can optionally include any of these system include files:
  <stddef.h>, <stdlib.h>, <stdio.h>, <stdarg.h>, <string.h>, <errno.h>.
  <limits.h>, <ctype.h>, <math.h>, <setjmp.h>

Such inclusion will be redundant with what is already provided here
by sim_defs.h.  Simulator code should include SCP provided include files:
  "scp.h", "sim_card.h", "sim_console.h", "sim_disk.h", "sim_ether.h",
  "sim_fio.h", "sim_imd.h", "sim_scsi.h", "sim_serial.h", "sim_tape.h",
  "sim_timer.h", "sim_tmxr.h", "sim_video.h"
depending on the specific needs of the device being simulated.

ae7ca950f2 3B2: Fix for diagnostics timer hang 
Under certain circumstances, the timer resolution in the Version 3
could become coarse enough that very short timer intervals would lead
to an infinite loop of bus errors when running timer firmware
diagnostics.

7be9f2f3e8 3B2: LPT Device; MMU and SCSI fixes 
This change adds support for printing to an attached text file via the
Centronics port of a simulated PORTS feature card. A new device named
"LPT" has been added. See "help lpt" for documentation.

Additionally, there has been a fix to a bug in the SCSI tape boot
implementation and a very minor bug fix to the Rev 3 MMU.

869dc0fe4a sigma: Correct recognition of pending DP seek interrupt. 
This corrects an error that caused SIO reject when SIO occured before
a pending seek interrupt on a different device.
 - Move the interrupt pending test from sigma_io.c into each device.
 - Make the sigma_dp.c test a special case that looks for pending
   seek interrupts.
