Arkadiusz Lichwa d63811079f Bluetooth: Adjust update connection params over L2CAP
The slave may request a change to the connection parameters using
the L2CAP LE signaling channel if either the master or the slave
or both do not support the Connection Parameters Request procedure.
Therefore if local controller doesn't support this, the request
can be made for sure.

Johan Hedberg a648bbe9a1 Bluetooth: SMP: Add local random number generation support
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.

Johan Hedberg 586d76b12a Bluetooth: Add support for reporting completed ACL buffers
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.
