[PATCH] core: add internet connectivity check

- Subject: [PATCH] core: add internet connectivity check
- Date: Sat, 22 Oct 2011 10:32:47 +0200
Hi,
here's the patch again. Forgot some code.
Cheers,
Tom
* use libsoup to check internet connectivity with
a http request to a configurable uri and check
the response code for 200
* do periodically check the connectivity. Check interval
is configurable
* check connectivity when device state change
from/to NM_DEVICE_STATE_ACTIVATED
