    texi: define new AM_TEXI2FLAGS variable
    
    To provide a bit more flexibility when invoking TEXI2DVI & TEXI2PDF,
    and provide a bit of symmetry with .info & .html generation, provide
    a AM_TEXI2FLAGS setting that is passed to all TEXI2xxx invocations.
    
    * doc/automake.texi: Mention new AM_TEXI2FLAGS setting.
    * lib/am/texibuild.am: Pass $(AM_TEXI2FLAGS) to TEXI2DVI & TEXI2PDF.
    * NEWS: Mention AM_TEXI2FLAGS.
    * t/txinfo-many-output-formats.sh: Check for AM_TEXI2FLAGS.
