This change introduces a new appop, ACTIVATE_PLATFORM_VPN, that is a
subset of the ACTIVATE_VPN appop. VPN apps that have been granted the
more dangerous ACTIVATE_VPN appop should be allowed to use platform
VPNs, as they are more restricted, and safer. However, the opposite
must not be true.

PhoneNumberUtils calls CountryDetector methods to ascertain whether a
number is an emergency number in the current country, but recent
emergency number detection changes have made the country an unused
parameter. Remove calls to CountryDetector to satisfy mainline
requirements wrt hidden APIs.

Subclassing Handler is not appropriate for a system API because
it is an implementation detail and allows users of this class to
post messages to the handler in ways that allow inappropriate
access to internals that aren't part of the API contract.

Also fix some lint errors.
