- fix Leap 42.2 build
* fcitx switched to DBus mechanism to select systray icon
which made it impossible to customize systray icon in
fcitx's themes. When the KDE default keyboard icon was
used, it was ugly-looking and invisible on small screens.
So we appended icons to openSUSE default Plasma themes
* in Leap 42.2 and Tumbleweed, our KDE team decided not to
provide any customization of the themes from kdebase4-openSUSE
package, so the customizations of systray icons are useless
in those systems.

- backport a upstream fix:
* boo#954623: fcitx prevents dropbox system tray
loading in KDE Plasma 5
* commit#c73761 : avoid unnecessary xembed tray
icon fallback, try harder to avoid touch tray
protocol related code when notification is
available or kimpanel is available.
* add patch boo954623.patch, delete next update

- Due to changes in kdebase4-openSUSE in Tumbleweed
%{_kde4_appsdir}/desktoptheme/{openSUSE,openSUSElight}
are no longer available. Actually those icon tweaks
are not needed too.

- update version 4.2.9.1
* support QPlatformInputContext::locale()
* correctly set input window position on scaled gtk3 application
* support unicode 8.0 in unicode module
* qt input context is not recreated correctly when fcitx restarts
