The scan response data is a better place to store the device name
since it has more space available and is also enforcing privacy.
When the controller is advertising, the connectable setting decides
if ADV_IND or ADV_NONCONN_IND is used. In case of ADV_IND, the
remote side is allowed to request the scan response data. Same as
with BR/EDR where either EIR is used or a remote name request. In
non-connectable mode, the device name is not available since it is
not allowed to request scan response data. Same as in BR/EDR where
the device is non-discoverable and no name requests are answered.

Instead of creating an new function pointer to report errors we are just
reusing state_change for that and there is a simple reason for this, one
place in the l2cap_core.c code needs, in a locked sk, set both the sk_state
and sk_err. If we create two different functions for this we would need to
release the lock between the two operation putting the socket in non
desired state.
The change is transparent to the l2cap_core.c code, user that only needs
to set the state won't need any modification.

The limited discoverable mode should be used when a device is only
discoverable for a certain amount of time and after that it returns
back into being non-discoverable.
This adds another option to the set discoverable management command
to clearly distinguish limited discoverable from general discoverable
mode.
While the general discoverable mode can be set with a specific
timeout or as permanent setting, the limited discoverable mode
requires a timeout. The timeout is flexible and the kernel will
not enforce any specific limitations. That GAP part of this is
required by userspace to enforce according to the Bluetooth core
specification.
Devices in limited discoverable mode can still be found by the
general discovery procedure. It is mandatory that a device sets
both GIAC and LIAC when entering limited discoverable mode.
