Some scenarios require a Broadcast Sink to complete the PA sync and BIG sync procedures separately. For example, a Broadcast Sink might synchronize to the periodic advertising transmitted by a Broadcast Source and it might detect that the BIG is encrypted, by looking at the BIGInfo advertising reports. If the Broadcast Sink doesn't know which Broadcast Code to pass as parameter to the BIG Create Sync command, it might learn it from a BASS Client through the Set Broadcast Code operation. Only then will it be able to successfully sync to the BIG. This patch implements defer setup support for the Broadcast Sink scenario: By setting defer setup on a broadcast socket before calling listen, the user is able to trigger the PA sync and BIG sync procedures separately.
