* INetworkListManager appears to depend on specific services to be able to work,
which one can actually disable while still getting full Internet connectivity.
* If that is the case, HRESULT_FROM_WIN32(ERROR_SERVICE_DEPENDENCY_FAIL) will be
returned, therefore we add a fallback to using InternetGetConnectedState(), which
does not have such dependencies (but has other limitations per b2492908be)
when we detect a dependency error.
* Also take this opportunity to switch to using INetworkListManager::get_IsConnectedToInternet().
* Also fix Coverity breakage due to Synopsys having upgraded their toolchain.
* Closes#1801
