Introduce a new optional job_done operation, which allows calling back
to the driver when a job is done. Since the job might be completed

This is a first attempt at implementing proper access to buffers
imported with dma-buf and used as reference frames for decoding
subsequent frames.
The main concern associated with this scenario was that memory could be
liberated while the buffer is not in a queued state. After careful

Because we need to request and release access to reference buffers
that are backed by a dma-buf import, keep track of the buffers used

To allow servers to verify client identity, allow a node
flag to be set that causes the sender's security context
to be delivered with the transaction. The BR_TRANSACTION
command is extended in BR_TRANSACTION_SEC_CTX to
contain a pointer to the security context string.
