[rygel/wip/basic-management: 67/68] core: Add a config flag for enabling BasicManagement



commit 4d2ec5752a682dc22ebf22d03bf82c9af850f32f
Author: Jussi Kukkonen <jussi kukkonen intel com>

    core: Add a config flag for enabling BasicManagement
    
    Remove the coupling to MediaRenderer: allow BasicManagement on any
    rygel plugin, provided the configuration specifies that diagnostics
    should be started.
    
    Add a "+DIAGE+" capability that is exposed in the device description
    when diagnostics is enabled.
    
    This change means that by default the service will not run. Add this to
    rygel.conf to enable:
      [Playbin]
      diagnostics=true
