This patch:
- adds a counter to ConnectStats for counting the number of successful
connect() calls done in blocking mode. This allows to compute error
rates for connect() in blocking mode.
- add printing of ConnectStats when dumping NetdEventListenerService
and/or IpConnectivityMetrics service.
Test: $ runtest frameworks-net, + manual tests verifying logged events.
