avoid deprecated gdk_display_get_screen and gdk_screen_get_number

I think we need GTK_VERSION_CHECK.
gdk_screen_get_number has been deprecated since version 3.22
https://developer.gnome.org/gdk3/stable/GdkScreen.html#gdk-screen-get-number
gdk_display_get_screen has been deprecated since version 3.20
https://developer.gnome.org/gdk3/stable/GdkDisplay.html#gdk-display-get-screen
Sadly, they use different versions.

thoughts?

@raveit65 done!

Docs say gdk_display_get_default_screen can be used since 2.2.

Also this changes the format of the internal messages that some plugins might use; did you check that all the plugins still work fine?

yes, I think this must work without the checks

Commit rebased again

Also this changes the format of the internal messages that some plugins might use; did you check that all the plugins still work fine?

plugins:

"external tools", "python console", "quick open" and "snippets" don't work with the tooltip message: "plugin loader 'python' was not found", so, I think it isn't related with the PR, can someone test it?

"modelines", "save without trailing spaces" and "tag list", I am not sure how to test, can someone test it?

the other plugins are working fine here

[monsta]

Ah dammit, lack of dependencies... you'll need to install libpeas-1.0-python2loader package 🙂

[monsta]

I think I'll check the code to find out which plugins actually use the message bus and where/when they do it...

[sc0w]

commit renamed and rebased with the other files with the deprecations

and, I am not sure, we need the checks for gtk in pluma.c?

[sc0w]

@monsta

PR updated, and now, I think doesn't change the format of the internal messages that some plugins might use

[monsta]

Looks ok to me now.
