If we get unbalanced input events we have a bigger problem with xkb_state_update_key which is documented with a warning that missed input events can result in stuck modifiers. As that call is just above, we either have a huge issue anyway or it works.</p></pre>

This change tracks how modifiers are used and detects a modifier only
key press/release. That is:
* no other key is pressed when the modifier gets pressed
* no other key gets pressed before the modifier gets released
If such a press/release is detected, we call a configurable dbus call.
The possible shortcuts can be configured in kwinrc, group
"ModifierOnlyShortcuts". The following keys are supported:
* Shift
* Control
* Alt
* Meta
As value it takes a QStringList (comma seperated string) with
service,path,interface,method,additionalargs
E.g. to invoke Desktop Grid effect on Meta key:
[ModifierOnlyShortcuts]
Meta=org.kde.kglobalaccel,/component/kwin/,org.kde.kglobalaccel.Component,invokeShortcut,ShowDesktopGrid
I do not intend to add a config interface for it. Let's keep it a hidden
way.</pre>
