#48969: glib2 @2.44.1: update version 2.46.0 as required by gtk3 3.18.0 and other
GNOME ports

 glib2 is currently stuck at version 2.44.1 due new features introduced in
 unstable version 2.45.3 that require Mac OS X 10.9+ to build.  The
 specific new feature involves a new GNotification backend that implements
 notifications using the current Mac OS X notification API available on
 10.9+.  This is a good thing but is not supported on older platforms.

 Per the comments recently committed to the glib2/glib2-devel ports, this
 issue is currently under discussion as follows:

 list/2015-September/msg00025.html [[BR]]
 https://bugzilla.gnome.org/show_bug.cgi?id=747146

 Unfortunately, this situation blocks progress on upgrading gtk3 to current
 version 3.18.0 as well as a number of other GNOME 3.18 modules released
 this week:


 {{{
 gtk3                  3.18.0 requires glib-2.0 >= 2.45.8
 gobject-introspection 1.46.0 requires glib-2.0 >= 2.45.3
 glib-networking       1.46.0 requires glib-2.0 >= 2.46.0
 gvfs                  1.26.0 requires glib-2.0 >= 2.45.7
 nautilus              3.18.0 requires gtk+-3.0 >= 3.17.5 glib-2.0 >=
 2.45.7
 tracker               1.6.0  requires glib-2.0 >= 2.45.3
 glibmm                2.46.1 requires glib-2.0 >= 2.46.0
 }}}

 I understand the desire to not break glib2 for the older platforms but we
 need to be able to move ahead with the latest versions of these modules on
 current Mac OS X platforms as well.

 My understanding of the discussion is that the upstream developers do not
 intend to do anything about this themselves but have pushed the issue back
 to us to deal with.  They suggest using the Growl package to implement
 GNotifications on the older platforms. They appear to be willing to accept
 relevant patches for review. So I think the ball is in our court.

 A minimal solution that seems feasible and could get us by this impasse
 would be to create a minimal patch to make the new feature optional and
 only enable it on 10.9 or later.  This shouldn't be a burden for the older
 platforms since we haven't had any notification support up to this point
 but would allow current platforms to take advantage of the feature.
