[PATCH BlueZ 0/9] Initial BAP support

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This set add initial support for BAP (Basic Audio Profile) which is
an essential part of LE Audio responsible for stream control.

The plugin is considered experimental and depends on ISO socket in order
to work so the following setting needs to be changed in order to enable it:

 # Enables D-Bus experimental interfaces
 # Possible values: true or false
+Experimental = true
 
 # Enables kernel experimental features, alternatively a list of UUIDs
 # can be given.

 # 6fbaf188-05e0-496a-9885-d6ddfdb4e03e (BlueZ Experimental ISO socket)
 # Defaults to false.

While proper support to the likes of PulseAudio and Pipewire are still
in progress it is possible to test using bluetoothctl with the following
commands:
