Reduce CONNECTIVITY_CHANGE bcasts
If an app uses the new api (requestNetwork) to bring up MMS, don't
mark it as a legacy request. This was done because the messaging
service had to use a combination of new API and old
(requestRouteToHost) due to api problems. This has been resolved
so don't mark these as legacy requests anymore.
The general stuff is still in for other types due to lack of testing
time but this should be removed altogether in the future.
