Make a limited subset of Tethering APIs public for DO/Carrier apps
to start Wifi tethering with a custom SoftApConfiguration.
The following APIs are needed to be moved to public
- TetheringManager
- startTethering
- stopTethering
- registerTetheringEventCallback
- unregisterTetheringEventCallback
- TetheringManager.TetheringRequest
- getSoftApConfiguration
- TetheringManager.TetheringRequest.Builder
- setSoftApConfiguration
- TetheringInterface
- TetheringEventCallback
- onTetheredInterfacesChanged
Checks for DO/Carrier apps will be added in a later CL.
