Make Lisp's (STATUS DATE) return 4-digit year

[ats@…]

In the DB ITS project, we've just changed MACLISP's (STATUS DATE) to return a 4-digit rather than 2-digit year: ​https://github.com/PDP-10/its/pull/1102

(STATUS DATE) was originally a thin wrapper around ITS's .RDATE call, which returns year % 100. Many of the programs that used it had Y2K problems as a result. Changing this to return the full year number directly has generally simplified the code that uses it.

At present, Multics MACLISP returns year - 1900 from (STATUS DATE); the implementation of this is in lisp_status_fns_.pl1 in >ldd>unb>source>bound_lisp_intprtr_.1.s.archive. It might be worth considering making the same change in Multics.
