Checking stderr form autoconf and autoheader

[Pavel Roskin]

Hello!

This patch makes the testsuite always check the stderr from autoconf and
autoheader. Intentional warnings (i.e. those produced by AC_MSG_WARN) are
suppressed by "-W none" whenever they are expected.

In one case the testsuite didn't check whether autoheader prints anything
to stderr when it exists with an error. Now it does.

ChangeLog:
        * tests/atspecific.m4 (_AT_CHECK_AC_MACRO): Check stderr from
        autoconf and autoheader. Expected warnings disabled by "-W none"
        Comment before that code removed as no longer relevant.
        * tests/semantics.m4 (AC_CHECK_PROG & AC_PATH_PROG): Check
        stderr from autoconf.
        (AC_PATH_PROG & AC_PATH_PROGS): Likewise.
        (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Likewise.
        * tests/tools.m4 (autoheader): Check that autoheader prints
        a warning for missing templates. Check stderr from autoconf.
        * tests/torture.m4 (config.status under extreme conditions):
        Check stderr from autoconf and autoheader.
        (command line interface): Check stderr from autoconf.

Regards,
Pavel Roskin
