Add "audio-device-selection-needed" which will be emitted when a headphones, headset or microphone is plugged into a jack socket that cannot detect which type it was. Once the user of libgnome-volume-control has asked the user which type of device this was, they can call gvc_mixer_control_set_headset_port() to switch the ports for that configuration. Note that gvc_mixer_control_set_headset_port() supports passing the card ID, but the detection code only supports a single such device. When we find hardware that can support > 1 such device, we can test and implement support without breaking the API. Based on the original code by David Henningsson <david.henningsson@canonical.com> for the unity-settings-daemon https://bugzilla.gnome.org/show_bug.cgi?id=755062
