  parallel-tests: add auxiliary script 'test-driver', refactor
  
  This refactoring should cause no API of functionality change,
  and is meant only to simplify the future implementation of TAP
  and SubUnit testsuite drivers.  More precisely, our roadmap is
  to move most of the "testsuite driving" features out of the
  Automake-generated Makefiles, and into external scripts with
  well-defined interfaces.  This will allow the user to define
  its own personalized testsuite drivers, and will also offer us
  a framework upon which to implement our new TAP and SubUnit
  drivers, all in a very unobtrusive way and retaining an high
  degree of code reuse and backward-compatibility.
  
  * lib/test-driver: New auxiliary script.
  * lib/Makefile.am (dist_SCRIPT_DATA): Add it.
  * automake.in (handle_tests): Require the new auxiliary script
  `test-driver', and define a new internal makefile variable
  `$(am__test_driver)', used to call it.  Perform new substitution
  on `DRIVER' when processing the `check2.am' file.
  * lib/check.am (am__tty_colors): Define new shell variable
  `$am__color_tests'.
  (am__rst_section): Removed, its role taken over by the new
  `test-driver' script.
  (am__test_driver_flags): New variable, contains the command
  line options passed to `test-driver'.
  (am__check_pre): Do not deal with temporary files and exit
  traps anymore, as the `test-driver' script takes care of that
  now.  Define shell variable `$am__enable_hard_errors', used by
  `$(am__test_driver_flags)'.  Reorder so that we don't need to
  save and restore the value of the `TERM' environment variable
  anymore.
  Other related adjustments.
  (am__check_post): Remove, as its role has been completely taken
  over by the `test-driver' script.
  * am/check2.am (?GENERIC?%EXT%$(EXEEXT).log, ?GENERIC?%EXT%.log,
  ?!GENERIC?%OBJ%): Call the test script through the Automake
  substituted `%DRIVER%', and honor the command-line options
  in `$(am__test_driver_flags)'.  Do not call the obsoleted
  `$(am__check_post)' anymore.
  * doc/automake.texi (Auxiliary Programs): Mention the new
  `test-driver' script.
  (Optional): Mention `test-driver' in AC_CONFIG_AUX_DIR.
  Since we are at it, break the list of auxiliary scripts by
  placing one per line, to simplify potential future additions
  of new scripts.
  * tests/check.test: Adjust.
  * tests/check2.test : Likewise.
  * tests/check3.test : Likewise.
  * tests/check4.test : Likewise.
  * tests/check10.test: Likewise.
  * tests/color.test: Likewise.
  * tests/color2.test: Likewise.
  * tests/comment9.test: Likewise.
  * tests/dejagnu.test: Likewise.
  * tests/exeext4.test: Likewise.
  * tests/maken3.test: Likewise.
  * tests/maken4.test: Likewise.
  * tests/parallel-tests-interrupt.test: Likewise.
  * tests/posixsubst-tests.test: Likewise.
  * tests/repeated-options.test: Likewise.
  * tests/check-no-test-driver.test: New test.
  * tests/parallel-test-driver-install.test: Likewise.
  * tests/Makefile.am (TESTS): Update.
  * NEWS: Update.
