[pulseaudio-discuss] [PATCH v0 08/11] bluetooth: Add hook to announce late UUIDs

[Mikel Astiz]

From: Mikel Astiz <mikel.astiz at bmw-carit.de>

UUIDs might be announced at any time, so a hook is needed to notify any
interested module. In practice, the UUIDs are quite stable with the
exception of the pairing procedure, where the UUIDs are reported by
BlueZ as soon as they are discovered.
