Bluetooth: mgmt: Add support for setting the local name
This patch adds a new set_local_name management command as well as a local_name_changed management event. With these user space can both change the local name as well as monitor changes to it by others. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F.
