12 * Inspects a multiplexed packet read from the remote. If this packet is a
13 * progress packet and thus should not be processed by the caller, returns 0.
14 * Otherwise, returns 1, releases scratch, and sets sideband_type.
16 * If this packet is SIDEBAND_PROTOCOL_ERROR, SIDEBAND_REMOTE_ERROR, or a
17 * progress packet, also prints a message to stderr.
19 * scratch must be a struct strbuf allocated by the caller. It is used to store
20 * progress messages split across multiple packets.
