Dear Maintainer,

After upgrading to ukui-settings-daemon 4.0.10.1-1, the daemon crashes
with SIGILL whenever a screen brightness change is applied.

The daemon is then respawned by kylin-process-manager and enters a
continuous crash/restart loop. While ukui-settings-daemon is not
running, global shortcuts provided by the media-keys plugin also stop
working.

Steps to reproduce:

   1. Start a UKUI session with ukui-settings-daemon 4.0.10.1-1 installed.
   2. Change the screen brightness using the settings UI, brightness keys,
   or D-Bus.
   3. Check the daemon status or coredumpctl output.

Actual result:

ukui-settings-daemon immediately crashes with SIGILL and is repeatedly
respawned by kylin-process-manager.

Expected result:

Changing the screen brightness should not crash ukui-settings-daemon,
and global keyboard shortcuts should continue to work normally.

Regards,

   [ zhangpan ]
   * Add missing return statements in gamma-manager, media-keys,
     input-device-manager, authority and common; without them the
     daemon died with SIGILL on every brightness change and all global
     shortcuts stopped working (Closes: #1146577).
   * plugins/global-manager: restore the isEnhancementBrightness(),
     isSupportGamma() and getAPPSecurityConfigPath() D-Bus slots used
     by the quick-settings plugins so the brightness slider is no
     longer greyed out (Closes: #1146578).
