[rygel/wip/basic-management: 77/95] core: Handle default parameter values in BasicManagement NSLookup

[Jussi Kukkonen <jussik src gnome org>]

commit 2b26be8a17a33f44351d13b9bbcf772c3bcbdd91
Author: Jussi Kukkonen <jussi kukkonen intel com>

    core: Handle default parameter values in BasicManagement NSLookup
    
    Add property setters for repetition and timeout, so the default values
    can be used for value '0'. repetitions still uses base class 'iterations'
    variable internally.
    
    Rename variables in BasicaManagement to be clearer.
