MacOS lacks ptsname_r, and gnulib doesn't (yet) provide it.
But we can avoid it altogether, by using gnulib openpty()
instead.  Note that we do _not_ want the pt_chown module;
all systems that we currently port to can either properly do
openpty() and/or grantpt(), or lack ptys altogether; we are
not porting to any system that requires us to deal with the
hassle of installing a setuid pt_chown helper just to satisfy
gnulib's ability to provide openpty() on even more platforms.

* .gnulib: Update to latest, for openpty fixes
* bootstrap.conf (gnulib_modules): Add openpty, ttyname_r.
(gnulib_tool_option_extras): Exclude pt_chown module.
* src/util/util.c (virFileOpenTty): Rewrite in terms of openpty
and ttyname_r.
* src/util/util.h (virFileOpenTtyAt): Delete dead prototype.


Thanks; pushed. I tweaked the commit message slightly to hopefully make it a bit clearer that openpty() includes the actions of grantpt() under the hood, and that the exclusion of pt_chown only affects platforms that lack both openpty() and grantpt().
