Freeze break requests for gnome-shell

[Florian Müllner <fmuellner gnome org>]

Hey,

I'd like to request a freeze break for two shell bugs:

 (1) https://bugzilla.gnome.org/show_bug.cgi?id=745824

      On multi-head systems, legacy status icons are visible

      even when the tray that holds them is slided out. I tracked

      this down to a bug in the hack that makes status icons

      usable on wayland, and while the code doesn't become less

     of a hack with the patch, the fix itself doesn't make it any worse
     and is pretty straight-forward.

     The bug is on the 3.16 blocker list, and we already got several

     duplicates since the tray first appeared in 3.15.91, so I think there

     are strong reasons for including it in 3.16.0.

 (2) https://bugzilla.gnome.org/show_bug.cgi?id=746487

      Legacy status icons are really bad when it comes to accessibility,

      but we can do a bit better than we currently do by trying to figure

      out a meaningful accessible name and passing on keyboard

      events in case the icon has alternative means to trigger the

      left-click/right-click actions.

      The patches are simple enough and will allow some users to use

      status icons that were otherwise unable to do so.

Neither of the bugs adds any translatable strings or changes documented behavior/visuals.

Thanks,

Florian
