Android T allows apps to declare a runtime receiver as not exported by invoking registerReceiver with a new RECEIVER_NOT_EXPORTED flag; receivers registered with this flag will only receive broadcasts from the platform and the app itself. However to ensure developers can properly protect their receivers, all apps targeting T or later registering a receiver for non-system broadcasts must specify either the exported or not exported flag when invoking #registerReceiver; if one of these flags is not provided, the platform will throw a SecurityException. This commit updates all the exposed receivers with a new RECEIVER_EXPORTED_UNAUDITED flag to maintain the existing behavior of exporting the receiver while also flagging the receiver for audit before the T release.
