Document the Bluetooth ACL layer. Remove unneeded parameters from the signalling command processing routines.

Change over the code so that the bluetooth packet data is read in by the stack rather than the user application, to make it more unform for sending/receiving, and so the library can handle incomming fragmentation in the future.

Start Service Discovery Protocol decoding and processing.
