[packagekit] pk network

[Zhu, Peter J]

Hi 

I don't understand two aspects of which network PK uses

1. What is pk-network-nm-dummy.c for?  From pk-network.c, if PK_BUILD_NETWORKMANAGER is NOT defined, which is the only way that dummy module enters into function, use_nm would be false which would render dummy module useless at all

2. it seems that no state-changed siganle emitted for pk-network-unix module
