NFC: LLCP late binding
With the LLCP 16 local SAPs we can potentially quickly run out of source
SAPs for non well known services.
With the so called late binding we will reserve an SAP only when we actually
get a client connection for a local service. The SAP will be released once
the last client is gone, leaving it available to other services.
