Helper functions for processing data streams in libvirtd Defines the extensions to the remote protocol for generic data streams. Adds a bunch of helper code to the libvirtd daemon for working with data streams. * daemon/Makefile.am: Add stream.c/stream.h to build * daemon/stream.c, qemud/stream.h: Generic helper functions for creating new streams, associating streams with clients, finding existing streams for a client and removing/deleting streams. * src/remote/remote_protocol.x: Add a new 'REMOTE_STREAM' constant for the 'enum remote_message_type' for encoding stream data in wire messages. Add a new 'REMOTE_CONTINUE' constant to 'enum remote_message_status' to indicate further data stream messsages are expected to follow. Document how the remote_message_header is used to encode data streams * src/remote/remote_protocol.h: Regenerate * daemon/dispatch.c: Remove assumption that a error message sent to client is always type=REMOTE_REPLY. It may now also be type=REMOTE_STREAM. Add convenient method for sending outgoing stream data packets. Log and ignore non-filtered incoming stream packets. Add a method for serializing a stream error message * daemon/dispatch.h: Add API for serializing stream errors and sending stream data packets * daemon/qemud.h: Add struct qemud_client_stream for tracking active data streams for clients. Tweak filter function operation so that it accepts a client object too. * daemon/qemud.c: Refactor code for free'ing message objects which have been fully transmitted into separate method. Release all active streams when client shuts down. Change filter function to be responsible for queueing the message
