Do not limit current-time-string to years 1000..9999.

* src/editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
(Fcurrent_time_string): Support any year that is supported by the
underlying localtime representation.  Don't use asctime, as it
has undefined behavior for years outside the range -999..9999.
* doc/lispref/os.texi (Time of Day): Do not limit current-time-string
to years 1000..9999.
* etc/NEWS: Do not limit current-time-string to years 1000..9999.
