  Parallel automake execution: AUTOMAKE_JOBS.
  
  * lib/Automake/Config.in (perl_threads): New global.
  * automake.in: Use it.  If the perl supports interpreter-based
  threading, then use `threads' and `Thread::Queue'.
  (handle_makefile, handle_makefiles_serial): New functions,
  factored out from main.
  (get_number_of_threads): New function, compute number of threads
  to use, based on environment variable `AUTOMAKE_JOBS' and number
  of independent makefiles.
  (handle_makefiles_threaded): New function.  Spawn threads, use
  thread queue to distribute handling the different makefiles.
  Collect $exit_code values from threads.
  (main): Use new functions.
  * aclocal.in: No threads here.
  * configure.ac: Substitute PERL_THREADS; enabled with perl >=
  5.7.2 and when ithreads are available.
  * bootstrap (dosubst): Likewise.
  * Makefile.am (do_subst): Likewise.
  * lib/Automake/Makefile.am (do_subst): Likewise.
  * lib/Automake/ChannelDefs.pm: Use `Automake::Config' and
  `threads'.
  (verb): Prepend thread ID (tid) to verbose messages.
  * lib/Automake/Channels.pm (msg): Before exiting, flush stderr,
  needed for worker threads.
  * lib/Automake/tests/Makefile.am (TESTS_ENVIRONMENT): Also
  include the build tree path, so Config.pm is found.
  * tests/parallel-am.test: New test.
  * tests/Makefile.am: Update.
  * doc/automake.texi (Invoking Automake): Document AUTOMAKE_JOBS.
  * NEWS, THANKS: Update.
  Report about long execution times by Joakim Tjernlund and others.
