tzsetup: upgrade to zone1970.tab

zone.tab is deprecated.  Install zone1970.tab alongside it, and use it
for tzsetup(8).  This is also useful for other applications that need
the modern better maintained file.

Add Makefile.depend.options

2019-12-19T04:58:11+00:00

Leaf directories that have dependencies impacted
by options need a Makefile.depend.options file
to avoid churn in Makefile.depend

DIRDEPS for cases such as OPENSSL, TCP_WRAPPERS etc
can be set in local.dirdeps-options.mk
which can add to those set in Makefile.depend.options

See share/mk/dirdeps-options.mk

Also update affected Makefile.depend files.

Revert the parts of r322097 related to /etc/wall_cmos_clock handling as

the previous behavior actually is required for setting up configurations
in which the RTC is using UTC but the timezone is not. Still, besides
uniform error handling, that file should get the same treatment in the
non-interactive variants supported by tzsetup(8).

- Move creation and unlinking of /etc/wall_cmos_clock from the handling

  of the initial UTC dialog to install_zoneinfo() so that file gets the
  necessary treatment also when that dialog is skipped via "-s", when
  selecting UTC from the time zone menu or on the command-line instead
  etc.
- Make the initial UTC dialog actually work by giving the relevant files
  the necessary treatment and then exit when choosing "Yes" there instead
  of moving on to the time zone menu regardless.
- Since r301131, /etc/localtime is also installed when selecting UTC in
  interactive configurations (which previously meant only via the time
  zone menu, though). Thus, the code added in r230298 which treats a
  NULL zone file name as UTC and removes /etc/localtime in that case can
  go again.
- Consistently refer to "could not delete" (as chosen by the oldest such
  code in here) when unlink(2) fails instead of a to mixture of "delete"
  and "unlink" in error messages.

Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones

This simplifies pathing in make/displayed output.

Fix build of tzsetup when WITHOUT_DIALOG is set

2016-10-22T22:35:39+00:00

Hide dialog specific code behind HAVE_DIALOG. It allows to build a stripped
down version (missing the dialog UI) but perfectly function tzsetup when
world is built WITHOUT_DIALOG

Reorganise a bit the code to limit the number of blocks under HAVE_DIALOG

Fix tzsetup not installing /etc/localtime for UTC

2016-06-01T15:39:11+00:00

If tzsetup UTC is run then it successfully configured the system for UTC
including installing /etc/localtime however if the user ran just tzsetup
for interactive configuration and select UTC no /etc/localtime was installed
which resulted in failures for utilities which require said file.

Change set_zone_utc to call install_zoneinfo("UTC") to ensure that
/etc/localtime is created for interactive UTC selection.

Users who have previously run tzsetup in interactive mode and select UTC
can install the missing /etc/localtime by running tzsetup -r.

Also correct static miss-match for set_zone_utc.
