		* communicate with the buffer pool. Via FMQ IClientManager sends
		* BufferStatusMesage(s) to the buffer pool.
		*
		* FMQ is used to send buffer ownership status changes to a buffer pool
		* from a buffer pool client. A buffer pool synchronizes FMQ messages when
		* there is a hidl request from the clients. Every client has its own
		* connection and FMQ to communicate with the buffer pool. So sending an
		* FMQ message on behalf of other clients is not possible.
		*
		* FMQ messages are sent when a buffer is acquired or released. Also, FMQ
		* messages are sent when a buffer is transferred from a client to another
		* client. FMQ has its own ID from a buffer pool. A client is specified
		* with the ID.
		*
		* To transfer a buffer, a sender must send an FMQ message. The message
		* must include a receiver's ID and a transaction ID. A receiver must send
		* the transaction ID to fetch a buffer from a buffer pool. Since the
		* sender already registered the receiver via an FMQ message, The buffer
		* pool must verify the receiver with the transaction ID. In order to
		* prevent faking a receiver, a connection to a buffer pool from client is
		* made and kept private. Also part of transaction ID is a sender ID in
		* order to prevent fake transactions from other clients. This must be
		* verified with an FMQ message from a buffer pool.
