[cctalk] Two items for RSTS/E

I just pushed two additions to https://github.com/pkoning2/decstuff : In "patches" a new patch for the DEUNA driver. This fixes a problem seen when doing user (as opposed to DECnet) I/O, as well as two errors that show up when using units beyond the first. Directory "ntp" is new. This is a simple NTP protocol client for RSTS, which will synchronize the system clock with an NTP server on the LAN. It includes handling of timezone rules, so the right thing will happen at daylight savings time (summer time) boundaries. The clock is maintained to the full RSTS resolution -- typically 1/50th or 1/60th second, but can be as low as 10 ms if the KW-11/P clock is used. paul
