legacysupport: provide clock_settime

[barracuda156]

Some ports need not only clock_gettime, but the reverse as well. For example #53928 but also other ones.

Is it possible to add it?

[fhgwright (Fred Wright)]

Anything's "possible". :-)

In most cases, the bulk of the work is in the test, rather than the implementation. In this particular case, it would have to be a manual test, for obvious reasons.

ntpsec is actually a poor example, since the unpatched upstream code has _way_ more issues than just clock_settime. I should know, since I'm the maintainer. :-)

In 9f6e0d24cf4b74cfc29645cfd4ac538fca580613/macports-legacy-support (master):

Implement clock_settime().

Closes: #71399

TESTED:
Passes the new (manual) test on all platforms.

legacy-support-devel: Update to latest master.

Notable changes since last -devel version:

• Fixes 10.4 Rosetta bug in fstatx_np()
• Makes renameat() available via stdio.h See: #71842
• Implements interim clock_gettime_nsec_np() See: #61691
• Implements clock_settime() See: #71399
• Adds net/if_tun.h for <10.6 See: #70231
• Provides pthread_[f]chdir_np() for 10.5+ See: #71265
• Adds CPU_TYPE_ARM definition for 10.4 See: #71621

Also adds Portfile comments regarding suggested github.tarball_from
change.

Also, the prior addition of vdprintf() in v20241026 neglected to close
the related tickets:

Closes: #67598
Closes: #70118

TESTED:
Tested both normal and -devel versions -/+universal on 10.4-10.5 ppc,
10.5-10.6 ppc (i386 Rosetta), 10.4-10.6 i386, 10.4-12.x x86_64, and
11.x-15.x arm64.
Builds and passes all tests on all tested platforms.
