[PATCH BlueZ 0/3] Broadcast source reconfiguration support

[PATCH BlueZ 0/3] Broadcast source reconfiguration support

[Silviu Florian Barbulescu]

This patch adds support for broadcast source to reconfigure a BIS.
endpoint.config command has a new prompt for broadcast source:
" This is a BIS Reconfiguration? (yes/no)"
Yes or y if a BIS reconfiguration is required
No or n if it is a new BIS configuration
"The BIS index is assigned in the order of the configuration
starting with 1"
"BIS Index (value):" a value representing the BIS index if this is a
BIS reconfiguration.

Instead of having a 2 step process we could ask the BIS index right
away and if the user answers no/0 it means it doesn't want to
reconfigure an existing index.

Lets not bypass layers here, so the config updates probably need to be
pushed thru bt_bap_stream somehow, perhaps via a new callback or a
state change where the transport.c can query the new configuration and
update its D-Bus property.
