    [ng] rules: forbid old-fashioned suffix rules, prefer pattern rules
    
    Pattern rules are cleaner, safer, and vouched for in the GNU make manual
    itself.  Supporting them instead of suffix rules will also allow us to
    simplify a little the automake script, auxiliary perl modules, and
    documentation.
    
    This change introduces a slight backward-incompatibility now, in that
    user provided definitions of the SUFFIXES variable or of the .SUFFIXES
    target, as well as old-fashioned suffix rules, are now rejected.
    
    Automake-NG still tries to parse and understand suffix-based pattern
    rules though, to retain support for user-added file extensions in the
    _SOURCES variables (see "Handling new file extensions" in the Automake
    manual).
    
    So, an usage like:
    
        SUFFIXES = .baz .c
        .baz.c:
                cp $< $@
        foo_SOURCES = foo.c bar.baz
        DISTCLEANFILES = bar.c
    
    which was valid with mainline Automake, should be translated for
    Automake-NG as:
    
        %.c: %.baz
                cp $< $@
        bin_PROGRAMS = foo
        foo_SOURCES = foo.c sub/bar.baz
        DISTCLEANFILES = bar.c
    
    Note that suffix-based pattern rules with dot-less suffix are *not*
    supported.
    
    * NG-NEWS: Update.
    * doc/automake.texi: Likewise.
    * lib/am/footer.am: Declare '.SUFFIXES:' with empty dependencies, to
    neutralize the default suffix rules.
    * automake.in (&handle_footer): Reject the 'SUFFIXES' variable.  Don't
    process its content anymore.  Don't generate the .SUFFIXES special target
    anymore.
    (&var_SUFFIXES_trigger): Remove.  And don't install it as an hook for the
    now-deprecated 'SUFFIXES' variable.
    * lib/Automake/Rule.pm (&define): Don't process old-fashioned suffix
    rules specially, but just reject them.  Instead, process pattern rules
    specially.
    ($_SUFFIX_RULE_PATTERN): Made local to the '&define' function, renaming
    it as '$suffix_rule_rx'.
    (&suffixes, @_suffixes): Delete, they are no more used.
    (@EXPORT): Adjust.
    (register_suffix_rule): Don't extend '@_suffixes' anymore.
    (reset): Don't reset '@_suffixes' anymore.
    * t/ext3.sh: Remove as obsolete.
    * t/suffix4.sh: Likewise.
    * t/suffix6.sh: Likewise.
    * t/suffix6b.sh: Likewise.
    * t/suffix7.sh: Likewise.

    * t/suffix-obj.sh: .. like this, and adjust.
    * t/suffix-chain.tap: Rewrite a as "simple" test (rather than as
    a TAP test), adjust, and rename ...
    * t/suffix-chain.sh: ... like this.
    * t/suffix3.tap: Likewise rewrite and rename ...
    * t/suffix3.sh: ... like this.
    * t/suffix8.tap: Likewise rewrite and rename ...
    * t/suffix8.sh: ... like this.
    * t/suffix10.tap: Likewise rewrite and rename ...

    [ng] rules: can pass deps to &Automake::Rule::define
    
    This change is only useful in view of future changes.
    
    * lib/Automake/Rule.pm (define): Add parameter '$deps' (still unused).
    Adjust comments and POD documentation.
    * automake.in (file_contents_internal, read_am_file) [/$RULE_PATTERN/]:
    Also pass the list of dependencies to the 'Automake::Rule::define'
    invocation.

    [ng] am: prefer pattern rules over old-fashioned suffix rules
    
    The use of pattern rules is cleaner, safer, and vouched for in the
    GNU make manual itself.  Moreover, it will allow us to obtain some
    simplifications in the automake script and the documentation in
    future changes.
    
    * lib/am/texinfos.am: Turn this suffix rules into pattern rules.
    * lib/am/texibuild.am: Likewise.
    * lib/am/depend2.am: Likewise.
    * lib/am/yacc.am: Likewise.
    * lib/am/lex.am: Likewise.
    * lib/am/lang-compile.am: Likewise.  Also, since we are at it, remove
    extra blank lines and quote 'like this' rather than `like this'.
    * t/ext.sh: Adjust.
    * t/objc-basic.sh: Likewise.
    * t/objcxx-basic.sh: Likewise.
    * t/txinfo6.sh: Likewise.
    * t/suffix.sh: Likewise.
    * t/suffix2.sh: Likewise.  Also, define a dummy LIBTOOL in Makefile.am
    instead of requiring the libtool macros.
    * t/cxx.sh: Remove as obsolete.
    * t/nodep.sh: Likewise.
