Checking error returned by L2CAP & SMP allows to fail Bluetooth
initialization in case something goes wrong.

The PACK_STRUCT macro will be removed soon and __packed is what all
code should use. Convert all the usages in Bluetooth code.

Add callbacks to notify L2CAP channels of connections, disconnections
and changes in the encryption state.

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.

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.

Add support for Security Manager Protocol fixed channel. SMP handling
would be done in smp.c.

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.

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.
