[Libguestfs] ANNOUNCE: libguestfs >= 1.23.5 will require Augeas >= 1.0.0

There are two parts to this change. (1) libguestfs >= 1.23.5 will require Augeas >= 1.0.0. Augeas is a library for parsing and editing Linux configuration files. Previously Augeas was optional, and that will remain true in libguestfs < 1.23.5. It has always been highly recommended because it's a great little library and if you don't have it then significant inspection features don't work. While fixing the following bug: https://bugzilla.redhat.com/show_bug.cgi?id=975412 I had to pick Augeas >= 1.0.0 [*], and at the same time I decided to make Augeas required. (2) Augeas 1.0.0 shipped with another bug which affects inspection: https://bugzilla.redhat.com/show_bug.cgi?id=904222 So if you are thinking of adding or updating Augeas in your distro in order to cater for (1), then it's worth also including the following patch which fixes this bug: https://github.com/hercules-team/augeas/commit/d6959e62 Rich.
