Remove duplication between private.h and zdump.c

* NEWS: Document this.
* asctime.c, strftime.c:
Do not include tzfile.h, since this source file is independent of
tz binary file format.
* private.h (TYPE_BIT, TYPE_SIGNED, INT_STRLEN_MAXIMUM, _)
(YEARSPERREPEAT, AVGSECSPERYEAR, SECSPERREPEAT)
(SECSPERREPEAT_BITS): Don’t worry about whether these are already
defined, as these macros are not intended to be overridden by the
user.
* private.h, tzfile.h (SECSPERMIN, MINSPERHOUR, HOURSPERDAY, DAYSPERWEEK)
(DAYSPERNYEAR, DAYSPERLYEAR, SECSPERHOUR, SECSPERDAY)
(MONSPERYEAR, TM_SUNDAY, TM_MONDAY, TM_TUESDAY, TM_WEDNESDAY)
(TM_THURSDAY, TM_FRIDAY, TM_SATURDAY, TM_JANUARY, TM_FEBRUARY)
(TM_MARCH, TM_APRIL, TM_MAY, TM_JUNE, TM_JULY, TM_AUGUST)
(TM_SEPTEMBER, TM_OCTOBER, TM_NOVEMBER, TM_DECEMBER)
(TM_YEAR_BASE, EPOCH_YEAR, EPOCH_WDAY, isleap, isleap_sum):
Move from tzfile.h to private.h, as these macros are independent
of file format.
* zdump.c: Always include private.h.
Do not include files that private.h already includes for us.
Remove definitions that are duplicates of what is in private.h.

Use angle brackets for system includes
This is the more-usual style nowadays, and makes it easier to
distinguish system includes from our includes.
