  Drop support for 'configure.in' as the Autoconf input file
  
  The autoconf input should be named 'configure.ac' instead.  The use
  of 'configure.in' has been deprecated in Autoconf since at least
  the 2.13 -> 2.50 transition, and future Autoconf versions (starting
  with 2.70 probably) will start to warn about it at runtime.  Automake
  has been warning about it since the 1.13 release.
  
  This change is basically a backport of commit 'v1.12-325-g927d4cb',
  from Automake-NG.
  
  * lib/Automake/Configure_ac.pm (find_configure_ac): Don't look for
  'configure.in' if 'configure.ac' is not found.
  (require_configure_ac): On failure, don't tell that "'configure.ac'
  or 'configure.in' is required", but just that "'configure.ac' is
  required".
  * automake.in (@common_sometimes): Don't list 'configure.in'.
  (scan_autoconf_files): Adjust heading comments.
  * NEWS: Update.
  * t/help.sh: Adjust.
  * t/configure.sh: Remove as obsolete.
  * t/list-of-tests.mk: Adjust.
