[pulseaudio-discuss] [PATCH v2 2/5] When switching ports, use the port default volume

If two ports have different default volumes, and module-device-restore
doesn't have an opinion on the port volume, we should change the
sink/source volume to the new port's default volume when switching
ports, instead of keeping the volume at whatever it happened to be
when the old port was active.
This introduces pa_sink/source_port_changed_hook_data, because I
wanted to call pa_sink/source_set_volume() only once in
pa_sink/source_set_port(), instead of calling it also in
module-device-restore's hook callback. The extended hook data allows
module-device-restore to communicate to the core that the volume
should be set to a non-default value.
