gnulib: posix-modules annotate

annotate posix-modules @ 17378:1d9362a18c34

Assume gnulib is checked out from Git, not CVS In fact, access to the gnulib repository through CVS has been disabled, or more precisely, got broken and was never restored; see: <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00008.html> Note that support for CVS is not removed completely and unthinkingly by this change: only support for CVS checkouts of gnulib itself is removed. For example, the 'bootstrap' script still cater to .cvsingore files and CVS directories, for the benefit of those poor gnulib clients still stuck with CVS. Ditto for the 'gnulib-tool' script itself. * gnulib-tool: Simplify accordingly. * posix-modules: Likewise. * MODULES.html.sh: Likewise. * doc/gnulib.texi: No longer mention the decommissioned CVS gnulib repository. * doc/gnulib-intro.texi: Likewise. * doc/gnulib-readme.texi: Likewise. * doc/gnulib-tool.texi: In the examples and explanations, refer to a sample '.gitignore' file rather than a sample '.cvsignore'. * NEWS: Update. * m4/extensions.m4: While at it, remove a comment mistakenly referring to "CVS Autoconf" rather than "git Autoconf".
