When connected, the peripheral/slave can trigger changing connection parameters.
Handle such request on central/master and if needed update controller settings
regarding the relevant connection parameters.

Adds internal HCI interface routine for creation of basic ACL LE link.
Most of the command interface parameters are fixed.
The internal interface is then used directly by simple public interface with
no connection validation.

When a connection is made, track its role.
Only peripherial/slave role may trigger update of L2CAP connection
parameters.

The PACK_STRUCT macro will be removed soon and __packed is what all

We use addresses in lots of places and with LE we always need to pass
around the type in addition to the address value. Defining dedicated
types for addresses makes the code much simpler.

Add an event handler for LTK requests that looks up the LTK using the

The SMP procedures require us to establish a local random number. Use
the HCI_LE_Rand command to generate the necessary 16 bytes (the
command needs to be called twice since it only returns 8 bytes at a
time). Store this number in the SMP context.
To help debugging with various crypto related values add a local h()
helper function for printk/BT_DBG to do hexadecimal conversion.

Every time we put a BT_ACL_IN buffer back to the pool we should report
this to the controller so it knows it can send us more data. This
patch makes the necessary modifications to the bt_buf_put() function
to trigger the HCI command.
The Host Number of Completed Packets command is special in that it
doesn't need to obey the reported ncmd value and also doesn't generate
any command status/complete events. Because of this we need an
exception for it in the bt_hci_cmd_send() function.

To start supporting controller to host flow control we need to tell
the controller our supported packet count & MTU and send the enabling
HCI command. This patch does the necessary addition to the HCI init
procedure.

This patch adds a simple event handler for the LE Disconnection
Complete HCI event. An extra thing the handler needs to do is to
re-enable advertising if necessary, since it will have been implicitly
disabled by the controller upon a connection event.
