For now, skip parallel tests under less-tested shells.
* tests/autotest.at (AT_CHECK_AT): Add pre-test argument.
(Tested programs, Startup error messages, AT_CHECK_AT_TITLE)
(Fallacy, Skip, errexit, Long test source lines)
(Debugging a successful test, Debugging script and environment)
(Debugging a failed test, Using atlocal)
(Choosing where testsuite is run): Adjust callers.
(AT_SKIP_PARALLEL_TESTS): New macro, to skip parallel tests except
under zsh, bash, or when TEST_PARALLEL_AUTOTEST is defined. Makes
it easier to avoid testsuite hangs for users with dash or other
less-tested shell.
(parallel test execution, parallel truth, parallel fallacy)
(parallel skip, parallel errexit)
(parallel autotest and signal handling): Use it.
* BUGS: Mention this.
