present or key doesn't meet auth requirements start pairing.

0fb7461140 Bluetooth: SMP: Set correct minimum encryption key size
For now we don't support key shortening, so set the minimum value
appropriately to 16 bytes. Once key shortening is implemented this
value can be lowered again.

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.
