Packaging: re-enable XDG_Shell for Tizen
The Weston has been upgraded to 1.5 and XDG_Shell basics for Weston 1.5 have been in oz-wl.
So we think it's time to re-enable it now. Meanwhile some related issues are under fixing. More changes will come in.
[Android] Enable the feature for onRequestFocus.

This patch is to enable the feature for onRequestFocus().
Call onRequestFocus() in activateContents().
[Android] Add test case for onRequestFocus.

This patch is to add test case for OnRequestFocus().
Clarify the application start URL fetching

This patch introduces a clear separation between
XPK and WGT code paths for fetching start URL.

It also removes deprecated and unneeded EntryPoints
flags from the Application class.
[Tizen] hardcode OZONE_WAYLAND_USE_XDG_SHELL env in service file

This change tells ozone wayland backend
that shell is supporting unstable xdg-shell.

This is needed for by tizen's Application.hide().

Alternative would be store this var in system wide env
ie: /etc/profile/crosswalk.sh
And eventually force a login shell (sh -l -c "...")
in this service file.

But for performance concern it's hardcoded there,
this change may be reverted later
if Tizen sessions decide to use login shells then it will work same.

Refer to this page for xdg-shell integration in Tizen :
