library/time.m: Deprecate non-pure functions `localtime/1' and `mktime/1'. They depend on the current time zone, which depends on the environment that the program is running in, and may also be changed at run time (e.g. by setting the environment variable "TZ"). Add replacement predicates `localtime/4' and `mktime/4' that thread the I/O state. Deprecate the non-pure function `ctime/1'. It does not seem necessary to add a pure replacement for it, being a minor convenience at best.
