[BlueZ,v2,7/8] client/player: Prompt the user to enter the bcode

Commit Message

Vlad Pruteanu Aug. 29, 2024, 9:52 a.m. UTC

This adds support for entering the broadcast code on sink side. When
the user selects a transport, if the transport is encrypted, the user
will be prompted to enter the broadcast code before the process of
transport selection can continue.
