shill: Unbind DHCPConfig from it's PID when dhcpcd is killed.

This allows the destruction of the DHCPConfig instance. The patch also
refactors and cleans up a bit resetting of client state in DHCPConfig.

BUG=chromium-os:37652
TEST=unit tests; tested on device by connecting to different APs, then
'stop shill' and inspecting logs for any stale DHCPConfig object
destructions; checked connectivity.
