Jaganath Kanakkassery 00457636f8 Bluetooth: RFCOMM: Initiate session connection 
This patch introduces the Connect API which initiates session
connection first. If session is already there with the peer
then it has to reuse it and initiate DLC (which will be done
in the subsequent patch) since there can be only one session
per device.

Jaganath Kanakkassery 2eba256fd2 Bluetooth: RFCOMM: Define enum and macros for role and CR 
This replaces initiator flag of session and dlc to enum which has
two values INITIATOR and ACCEPTOR.

Also this defines macros for CRs in header. Basically there are
three types fo CRs. Frame header CR has different meaning for
UIH and non UIH packets. Also this renames the existing msg hdr
CR to make it consistent.

These changes are basically done to make it more readable

Johan Hedberg 6bc645962a Bluetooth: Move Bluetooth host stack to subsys 
Move the Bluetooth host stack from net/bluetooth to
subsys/bluetooth/host. This is preparation for having both host and
controller under the same root, i.e. subsys/bluetooth/.
