  tests: use 'parallel-tests' Automake option by default
  
  This will help our transition from 'serial-tests' to 'parallel-tests'
  as the default test suite driver enabled by a TESTS assignment in the
  input Makefile.am.  Note that that change of default will only take
  place in master, though.
  
  * defs: Pass the 'parallel-tests' option to the AM_INIT_AUTOMAKE
  invocation in the created 'configure.ac' stub, unless the variable
  'am_serial_tests' is set to "yes".  Don't pay attention anymore to
  the 'am_parallel_tests' variable, that's obsolete now.
  * defs-static.in: Warn if the 'am_serial_tests' variable is set in the
  environment; conversely, don't warn anymore about 'am_parallel_tests'
  being set in the environment.
  * Makefile.am (AM_TESTS_ENVIRONMENT): Nullify the 'am_serial_tests'
  variable instead of the now-obsolete 'am_parallel_tests' one.
  * syntax-checks.mk (sc_tests_obsolete_variables): Also warn against
  uses of 'am_parallel_tests', which is now deprecated in favor of
  'am_serial_tests'.  Similarly, if a use of 'parallel_tests' is seen,
  suggest using 'am_serial_tests' instead, not 'am_parallel_tests'.
  * gen-testsuite-part: Now that we use the 'parallel-tests' by default
  in our tests, we need to completely change the logic and semantics of
  generation of sibling tests for those tests that check the Automake
  generated testsuite harness itself.  Do that, and give a complete
  explanation of the new logic and semantics in the relevant comments.
  * t/README: Update.
  * Lots of test cases: Adjust.

  # Test for a behaviour of 'TESTS_ENVIRONMENT' and 'AM_TESTS_ENVIRONMENT'
  # w.r.t. file descriptor redirections which, although undocumented,
  # is nonetheless required by Gnulib's 'tests/init.sh' and by coreutils'
  # testsuite.
  # The checked behaviour is that we can portably do file descriptor
  # redirections by placing them at the end of a {AM_,}TESTS_ENVIRONMENT
  # definition without a following semicolon.  The need to support this
  # is detailedly motivated by coreutils bug#8846:
  #   <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8846>
  # and the following CC:ed thread on bug-autoconf list:
