* Removed the i386ancient standalone tarball build for linux, which
was increasingly unable to support new git-annex features.
* Removed support for building with ghc older than 9.0.2,
and with older versions of haskell libraries than are in current Debian
stable.
* stack.yaml: Update to lts-23.2.
Note that i386ancient was targeting linux 2.6.32, which has been EOL for
over 9 years now. Any old system still using such a kernel is certainly highly
insecure. And I suspect i386ancient had its own insecurities due to haskell
libraries and C libraries not having been updated.
Better to advance while suspended, that way a stale content retention
lock will expire while suspended.
The fallback the Monotonic to support older kernels assumes that there
are not systems where Boottime sometimes succeeds and sometimes fails.
If that ever happened, the clock would probably not monotonically
advance as it read from different clocks on different calls! I don't see
any indication in clock_gettime(2) errono list that it can fail
intermittently so probably this is ok.
