time: move time functions out of lib.c into time.c.

* Makefile (OBJS): Add new time.o.

* eval.c (eval_init): Registration of time functions is
removed from here; it is done in time_init now, in time.c.

* hash.c: Must #include "time.h" now.

* lib.c (time_s, time_local_s, time_utc_s, time_string_s,
time_parse_s, year_s, month_s, day_s, hour_s, min_s, sec_s,
dst_s, gmtoff_s, zone_s): Variable definitions removed.
These are now in time.c. Also declared in time.h.
(time_sec, time_sec_usec, gmtime_r, localtime_r, string_time,
time_string_local, time_string_utc, broken_time_list,
tm_to_time_struct, broken_time_struct, time_fields_local,
time_fields_utc, time_struct_local, time_struct_utc,
time_fields_to_tm, time_struct_to_tm, make_time_impl,
make_time, epoch_tm, strptime_wrap, time_parse, setenv,
unsetenv, timegm_hack, make_time_utc, time_meth,
time_string_meth, time_parse_meth, time_parse_local,
time_parse_utc): Functions removed. These are now in time.c.
(time_init): Removed, and now in time.c as an external
function.

* lib.h (time_sec, time_sec_usec, time_string_local,
time_string_utc, time_fields_local, time_fields_utc,
time_struct_local, time_struct_utc, make_time, make_time_utc,
time_parse, time_parse_local, time_parse_utc): Declarations
removed. Now in time.h.

* rand.c: Must #include "time.h" now.

* time.c: New file.

* time.h: New file.
