[Bluetooth] Add support for handling simple eSCO links
With the Bluetooth 1.2 specification the Extended SCO feature for better audio connections was introduced. So far the Bluetooth core wasn't able to handle any eSCO connections correctly. This patch adds simple eSCO support while keeping backward compatibility with older devices. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
