Review request for KDE Frameworks and Matthew Dawson.


Repository: kconfig


Description
-------

When opening a KSharedConfig, the OpenFlags must match to share the underlying config object. Otherwise a new KConfig is created and the benefit of using KSharedConfig is lost. This was triggering subtle bugs with the use of KConfigLoader in plasmashell.

This patchset adddress that issue by exposing the OpenFlags used to open a KConfig.

Another approach would be to add another KSharedConfig::openConfig() which takes a KConfig object and uses that in its search for a matching pointer object, and then use that version of openConfig if KSharedConfig

Testing
-------

Used KConfigLoader in startup config of plasmashell and settings are now propagated correctly from the shell scripting to the config loader objects.
