This version adds support for openmpt, pipewire and snapcast, which are
disabled for now.
It also adds support for a choice between pupnp and npupnp for the UPnP
database. Therefore, the UPNP option is converted into three-value
choice in Config.in. Legacy handling of the BR2_PACKAGE_MPD_UPNP makes
sure that upnp remains selected.
