check: the parallel-tests driver is now the default

The old serial testsuite driver is still supported, and can be activated
by the 'serial-tests' option (introduced by commit 'v1.11-1989-gdeb7773'
of 2012-02-20, "automake: new option 'serial-tests'").

* lib/Automake/Options.pm: Now, the 'parallel-tests' option is a no-op
(but still explicitly recognized, for backward compatibility), while the
'serial-tests' option is recognized and registered.
* automake.in: Adjust to ensure that the parallel test harness is used by
default; mostly, this amounts at using "! option('serial-tests')" where
"option('parallel-tests')" was used before.
* NEWS, doc/automake.texi: Update.
* configure.ac (AM_INIT_AUTOMAKE): Drop 'parallel-tests' option, is
redundant now.
* defs: In the generated AM_INIT_AUTOMAKE call, use the 'serial-tests'
when the serial testsuite harness is to be used, and no option otherwise.
* lib/am/check.am: Use (static) conditional '%SERIAL_TESTS%' instead of
conditional '%PARALLEL_TESTS%'.
* lib/test-driver: Adjust heading comments.
