Adds host bits to initiate LL LE Exchange Feature procedure if
supported. Both the master and slave can initate it for controllers
newer than 4.0. For 4.0 controllers only master can do that.
Inform upper stack layers of the slave about the connection is ready
to use only when LE Exchange Feature isn't supported. Otherwise
upper layers shall be notified about new connection when Connection
Parameters Update procedure is finished.

According to Core vol.3, part A 4.20, if we operate in slave mode,
and we receive a Connection Parameter Update Request, we should
respond with a Command Reject with reason Command not understood.

Rename the hci_core.c (previously internal) variable 'dev' to 'bt_dev'
and export it through hci_core.h. This way e.g. bt_conn doesn't need
to store an internal reference to it.

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.

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.

writer would need to go and enable the specific ones that they're

There's no point in encoding the ACL header in bt_conn_create_pdu()
since ultimately we might end up having to split the data into
multiple buffers - each with their own ACL header. Instead, move the
header encoding into bt_conn_send() where we can later add the proper
fragmentation support.
