6487d319cd VMS Build: Restore VAX/VMS host build support 
The C RTL on the latest VAX/VMS does not provide a snprintf function.
We provide a 'basic' one which meets the needs of simh as suggested
by Jordi Guillaumes Pons.

00f8bbcef1 3b2: Time of Day Clock 
- This change adds support for storing time between boots in the Time
  of Day clock. An effort has been made to keep the Time of Day clock
  in sync with the wall clock between boots, so that user-set time
  advances properly between boots.

- Added a couple of custom help routines for TOD and NVRAM.
  I will be filling in more help routines as time permits.

690c30b6f4 3b2: Gracefully handle clock reset 
Clock reset was not being handled gracefully at all, leading some
diagnostic tests not to pass, or not to pass consistently.

This change will "kick" the system clock whenever the timer divider is
reset, so the new divider is picked up immediately.
