Change provider packages API to test all providers

This will replace the LocationManager.getNetworkProviderPackage() API
with LocationManager.isProviderPackage(). The network provider should
not be considered special.

In addition, providers now have the ability to specify additional
packages that may make location requests on their behalf, so that those
packages can be considered location providers as well.

Test: manually
