    automake: remove support for threaded execution
    First, It add lots of complexity to the Automake script, which might
    get in the way of future refactorings.
    Also, the performance enhancements it offers seems to be fairly
    albeit not excessively so:
    In the end, the most relevant reason for this change is that we want to
    reach a point, during the yet-to-come maturity of Automake-NG, where it
    will be just a thin layer around the provided scripts and makefile
    fragments (with just a *tiny* smattering of preprocessing), as well as
    around autom4te (for the proper parsing of  At such a
    point, a threaded execution would bring no real benefit.
    Oh, and we should really be pushing peoples towards non-recursive
    build systems, where they just have one '', and thus
    threading on different ''s is irrelevant ;-)
    * NG-NEWS: Update.
    * doc/automake-ng.texi, NG-NEWS: Likewise.
    * Don't check for 'ithreads' support in perl.
    * (PERL_THREADS): Don't define.
    (dosubst): Don't substitute it.
    * lib/Automake/ ($perl_threads): Define no more.
    (@EXPORT): Drop it.
    * ($perl_threads): Remove, no more needed.
    * (BEGIN) [$perl_threads]: Don't require nor import
    the 'threads' and 'Thread::Queue' modules.
    Delete constants.
    ($required_conf_file_queue): Delete variable.
    ($nthreads): Likewise, and thus ...
    (get_number_of_threads): ... delete this function, whose only
    purpose was to initialize that variable.
    (handle_makefiles_serial): Delete, its body inlined in the main
    (require_file_internal): Don't take the '$QUEUE' argument, nor
    handle threading/serialization calling back ...
    (queue_required_file_check_or_copy): ... this function, which
    has thus been removed.
    (require_libsource_with_macro): Adjust 'require_file_internal'
    call to new signature.
    (require_conf_file): Likewise, in the process dropping any
    handling of threading/serialization.
    (handle_makefiles_threaded): This is no more called anywhere,
    so delete it, together with ...
    (require_queued_file_check_or_copy): ... this, which has in
    that its only caller.
    * lib/Automake/ (serialize, deserialize): Delete
    as unused.
    * lib/Automake/ (setup_channel_queue,
    pop_channel_queue): Likewise.
    (@EXPORT): Adjust.
    (BEGIN) [$perl_threads]: Don't require nor import 'threads'.
    (%_default_options): Remove 'ordered', 'queue' and 'queue_key'
    keys, that were only required for serialization during threaded
    (_merge_options, _print_message): No need to handle those
    Adjust creation of channels 'automake', 'verb' and 'fatal'.
    (_enqueue, _dequeue): Delete as unused.
    (msg): Adjust a comment.
    (verb): Don't try to display informations about the current
    * lib/Automake/ (CLONE): Delete, no more
    * t/ax/ (require_tool): Drop handing of
    requirement 'perl-threads'; it is not used by any test now.
    * t/ Remove as obsolete.
    * t/ Likewise.
    * t/ Likewise.
    * t/pm/ Likewise.
    * t/pm/ Likewise.
    * (check-coverage-run, recheck-coverage-run): Don't
    export 'WANT_NO_THREADS' to "yes", nor unset 'AUTOMAKE_JOBS'.

    Merge branch 'master' into ng/master
    * master: (39 commits)
      typofix: in a comment in
      maintcheck: fixup list of files in $(xdefs)
      tests: never source directly, source instead
      runtest: sanitize test environment
      tests: remove an obsolescent self test
      tests: "am_using_tap=yes" -> "am_test_protocol=tap"
      tests: protect test libs against multiple inclusion
      configure: testsuite shell can return early from "dot-sourced" files
      tests: move sanitization and "Bournification" in the generic test lib
      tests: source test defs in the generic test lib
      test defs: no need to re-add $srcdir/t/ax to $PATH
      tests: split test libs into "generic" and "automake-specific"
      test setup: move actual calling of testsuite setup in ./defs
      test setup: merge definitions of function for simple tests
      test init: refactor: new function 'am_test_setup'
      test init: refactor: move displaying of debugging info later
      test init: refactor: new function 'am_setup_testdir'
      test init: refactor: new function 'am_set_exit_traps'
      configure: testsuite shell set exit traps in shell functions
      test init: refactor: new function 'am_exit_trap'
    + Extra non-trivial edits:
    * (perf_TESTS): Define here, as 't/' is gone
    in the 'ng/master' branch.
    (all_TESTS): Don't list tests in 't/perf'; this reflects the removal of
    $(perf_TESTS) from $(handwritten_TESTS) done in 't/' on
    the 'master' branch.
    * t/ Source '', not './defs-static'.
    Also, simply use:
    instead of:
        . "$am_testauxdir"/
    to source the helper shell script ''.  See recent
    commit 'v1.12.2-49-g42fb45b' for a rationale.
    * t/ Likewise.
    * t/ Likewise.
    * t/ Likewise.
