Update gtk+3.0 to 3.22.25

[Jeremy Bícha]

Impact
======
There is a new gtk3 release, 3.22.25.

Highlights
----------
* Allows dropping these cherry-picked patches:
  - 0001-Adwaita-Fix-typo-.backgrounf-.background.patch
  - 0002-theme-Fix-Adwaita-headerbars.patch
 - 0003-display-x11-Unset-tiled-state-if-_GTK_EDGE_CONSTRAIN.patch
* Fixes crash with GNOME Online Accounts (LP: #1720400)
* Fixes menu forwarding over SSH (LP: #1700319)
* Fixes log spam about cursor when running gnome-terminal on Wayland (LP: #1681910)
* Support KDE SSD (server-side decorations) handling on Wayland
* Restores middle-click to do the opposite of primary (usually left-) click in scrollbars, GTKRange
* Some theme fixes for the gtk3 High Contrast theme
* Allow more key buttons in the GNOME Settings > Keyboard panel to be translatable
* A fix to not show duplicate printers in some cases
* Improves the GNOME 3.26 tiling feature for GNOME Terminal

For more changes since 3.22.24, see
https://git.gnome.org/browse/gtk+/log?h=gtk-3-22
https://git.gnome.org/browse/gtk+/tree/NEWS?h=gtk-3-22

Test Case
=========
Install the update. Run a variety of apps in the default Ubuntu install with the Ambiance theme.

Also check that the Adwaita and High Contrast themes still look ok. You can change the theme with the GNOME Tweaks app (gnome-tweak-tool). For the window buttons to look as designed, you should change the icon theme to Adwaita when you set the theme to Adwaita or High Contrast. Afterwards, you can reset your theme back to the defaults with
gsettings reset org.gnome.desktop.interface gtk-theme
gsettings reset org.gnome.desktop.interface icon-theme

Regression Potential
====================
Quite a few changes, but mostly it's bug fixes.

Earlier gtk3 releases had some regressions (that's why we had those cherry-picked patches), but that was mostly related to the late GNOME 3.26 tiling feature that was rushed in. This release does not have any major new features like that.

Unfortunately, very few people run gtk3 from git master so regressions often aren't seen until distros start shipping the gtk3 update.

The GNOME stack has an SRU Micro-release exception
https://wiki.ubuntu.com/StableReleaseUpdates#GNOME

We haven't done micro-release SRUs for gtk3.22 yet. This might be a good trial run to see how well it works before 18.04 LTS. Fedora does keep their gtk3 up to date throughout the life of their releases.

Other Info
==========
This update also drops a few old patches that weren't listed in debian/patches/series. Sorry about the noise but this makes it a bit cleaner in the future.

0001-Update-the-GDK-Mir-backend-to-fix-a-few-problems.patch
0001-Improve-external-drives-detection.patch
0002-fix-other-locations-with-glib-249.patch
0003-use-null-for-generic-marshallers.patch

I have been using gtk 3.22.25-0ubuntu0.1 for several days on Ubuntu 17.10 and haven't noticed any regressions. The Adwaita, Ambiance and HighContrast themes look as expected.

The verification of the Stable Release Update for gtk+3.0 has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
