[Automake-NG] [PATCH 14/26] [ng] texi: adjust names of vars used for silent rules support

[Stefano Lattarini]

* lib/am/texibuild.am, automake.in (define_verbose_texinfo): Modify
so that the variables $(AV_texinfo) and $(AM_texidevnull) get renamed
with the much clearer and more proper names $(AM_TEXI_QUIETOPTS) and
$(AM_TEXI_DEVNULL_REDIRECT).
* t/silent8.sh: Enhance.
