From 2c0273e50a3162595e9a54030166f2369b039a5a Mon Sep 17 00:00:00 2001

Subject: Add a flag for multiple triggers with same recognition session

Also annotate the flags with @IntDef to make things clearer and safer

Add more debug logging

Revert to start/stop being synchronous since telephony and microphone will
need to be handled internally.
