Johan Hedberg 7650dabdab Bluetooth: Add L2CAP callbacks for connection state changes
Add callbacks to notify L2CAP channels of connections, disconnections
and changes in the encryption state.

Johan Hedberg 0b099acb4c Bluetooth: Add registration mechanism for L2CAP channels
We'll either way need various callbacks as well as get rid of the
channel-specific contexts in conn.h, so add a dynamic way of
registering fixed channels. The LE signaling channel is handled in the
same way as any other channel.

Johan Hedberg 44e67698a6 Bluetooth: Move L2CAP header encoding to sending stage
Encoding the L2CAP header when allocating the buffer means that we
must know the final size up-front. This is not always possible, so
move the header encoding to bt_l2cap_send() and only have the
bt_l2cap_create_pdu() function reserve enough headroom without
actually encoding anything.

Andrei Emeltchenko 69f94f2484 Bluetooth: Add skeleton for SMP handling
Add support for Security Manager Protocol fixed channel. SMP handling
would be done in smp.c.

Johan Hedberg c31237aa82 Bluetooth: Add basic L2CAP support
This patch adds basic L2CAP functions, including support for the LE
signaling channel as well as performing a connection parameter update
in slave (peripheral) role.

Johan Hedberg 4831529193 Bluetooth: Add connection abstration
This patch adds a new bt_conn struct which abstracts the details of an
connection. Each connection has two fibers: one for incoming and
another for outgoing data. For now only one connection is supported.
The patch also adds a basic L2CAP header definition so that fragmented
ACL packets can be properly parsed.
