python3 gtk3 client feature parity

[totaam]

Follow up from #1717, still TODO:

• launcher doesn't have "advanced" mode encoding selection
• pointer grabs don't work with GTK3? we should also add an event listener for:
  EventGrabBroken
• opengl rendering context does not work with override-redirect windows on win32 (disabled in r18391), though no errors are reported anywhere..
• macos mouse wheel, see also: ​Gdk.Window.set_support_multidevice - maybe GTK3 can give us per-device events? (will they be normalized?)
• macos fullscreen doesn't work with GTK3?
• macos cmd-q crashes? (see no longer control encoding in config file (macos/OS X client) #1766#comment:21)
• macos: after maximize the screen is offset upward (see no longer control encoding in config file (macos/OS X client) #1766#comment:26)
• win32: crash with firefox's proxy authentication dialog (when firefox started after connecting only?)
• for fine grained scrolling (uinput virtual pointer device #1611), we should use gdk-event-get-scroll-deltas, for python see How to use the Python GTK3 (gi.repository) gdk_event_get_scroll_deltas() method
• the gtk crasher bug is still not fixed: Crash when accessing the "string" attribute of GdkEventKey on 64bit Windows

Some GTK tickets have been closed when they moved to gitlab and we may want to re-open them:

• GtkWindow.Fullscreen() does not work correctly with multiscreen on OSX
• set_geometry_hints max_width/max_height not honoured on win32

[totaam]

The key event crasher bug may has been fixed upstream: see #1902#comment:6 and r20421.

Python3 ticket: #1568

Still TODO:

• client session info graphs
• fix appindicator3: statusicon doesn't work with the latest gnome-shell.. See tray menu is unusable on Ubuntu #2179 and fix appindicator so we can use it for forwarding system trays #406.

• appindicator issues are tracked in fix appindicator so we can use it for forwarding system trays #406 and tray menu is unusable on Ubuntu #2179
• session info graphs moved to session info graphs missing with gtk3 #2195
