Introduce a generic netlink multicast event to report binder transaction failures to userspace. This allows subscribers to monitor these events and take appropriate actions, such as stopping a misbehaving application that is spamming a service with huge amount of transactions. The multicast event contains full details of the failed transactions, including the sender/target PIDs, payload size and specific error code. This interface is defined using a YAML spec, from which the UAPI and kernel headers and source are auto-generated.
