Subject: [PATCH 1/1] Fix session management broken since KF5 / Qt5.
Requires Qt 5.6 branch not more than a few days old, or >= 5.6.0
when it is released.
Parts of the fix are:
- Call QGuiApplication::setFallbackSessionManagementEnabled(false)
to prevent application suicide through a mechanism that tries to
help applications without any proper session management support,
but badly interferes with applications that do implement proper
session management, such as KDE applications.
- Add back commitData[Request] handling. For some reason it was
removed during porting.
- Change the returned types of saveState() and commitData() to void.
The return values were unused.
