Preventing accidental misuse of registerReceiver

A new BroadcastFilter was being created even when the caller called
registerReceiver with the same receiver and intent filters as an earlier
call. While resolving, only the first object added was being used.
Also, limiting the number of receivers that an app can register, so
badly written code does not end up causing memory or computational
pressure on the system.

Test: Manual, and
atest android.content.BroadcastReceiverTests#testReceiverLimit
