Add support for mgmt interface events for device blocking/unblocking.
Kernel sends a mgmt event when a device has been blocked by another
management socket or with ioctl command (e.g. by hciconfig).
Parameter update_only is added to device_block/unblock functions in
device.c to avoid code copying. When update_only is true, blocking
command is not sent to kernel, but only device status is updated and
dbus signal is sent.
This patch adds a new set_local_name command as well as a
local_name_changed event to the management interface. Instead of 248
bytes (like in the HCI spec) 249 bytes are always reserved for the name
in the messages so that there's a guarantee of it being nul-terminated
(this is not guaranteed on the HCI level).
This patch updates the class of device handling code to match the latest
management interface. A notable feature is that UUID to service class
mapping policy remains in user space with the help of the svc_hint
parameter of the add_uuid command. This is to make it easy to update the
mapping table when new profiles come along.
This patch adds support for the add_uuid and remove_uuid management
commands. The kernel uses them to track the list of UUIDs and
automatically set the service class bits as well as the EIR value
accordingly.
This patch implements support for the set_pairable managment command.
Due to the async nature of it a new btd_adapter_pairable_changed
function is added to the core daemon.
The events, commands and responses to these modes are represented by
identical management messages. By having a unified struct for all of
them quite a lot of code can simplified and reused.
The current idea is to have a single set_powered management command
which for the switching on case would leave the controller in a
non-connectable, non-pairable and non-discoverable state.
The read_mode and read_info commands are issued only once in the
beginning for each adapter so it doesn't make sense to have the
information fetching split across two different commands. Instead all
necessary info can be fetched through the read_info command.
