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.

3eadc405d0 PDP10: Ignore 0 value writes to the timer interval register 
This avoids a divide by zero which is never right, but it is unclear
what the real hardware did.  It wouldn't be useful in any case.

- Don't count stalls as drops since they can be retried

   happen more frequently on serial port connections.

paces mux output so that reasonable behavior is observed.

 - SEND AFTER=ttt "some string"
     --> uses the "ttt" temporary value for this SEND only

(and similarly for the SEND DELAY value).
