Some times plugin needs to let user associate some of its own config
with a specific source. To this end, it will be much easier to let
user specify said source by name. Something like:

ncsource=wlan0:name=src1
my_plugin_item=src_name=src1,foo=bar

Function below lets plugin find a source by name.
