[Bluetooth] Use ACL config stage to retrieve remote features
The Bluetooth technology introduces new features on a regular basis and for some of them it is important that the hardware on both sides support them. For features like Simple Pairing it is important that the host stacks on both sides have switched this feature on. To make valid decisions, a config stage during ACL link establishment has been introduced that retrieves remote features and if needed also the remote extended features (known as remote host features) before signalling this link as connected. This change introduces full reference counting of incoming and outgoing ACL links and the Bluetooth core will disconnect both if no owner of it is present. To better handle interoperability during the pairing phase the disconnect timeout for incoming connections has been increased to 10 seconds. This is five times more than for outgoing connections.
