bthidev -- Bluetooth Human Interface Device support

The bthidev driver handles all Bluetooth Human Interface Devices. Each
HID device can have several components, e.g., a keyboard and a mouse.
These components use different report identifiers to distinguish which
component data is coming from. The bthidev driver may have several chil-
dren attached that handle particular components and dispatches data to
them based on the report id.
Normally, Bluetooth HIDs will be attached using the btdevctl(8) program.
The following properties are used by the bthidev driver during autocon-

remote-bdaddr Remote device address.
service-name The bthidev driver matches the `HID' service.
control-psm This, if set, will indicate the PSM to use for the Con-
trol channel. If not set, L2CAP_PSM_HID_CNTL will be
interrupt-psm This, if set, will indicate the PSM to use for the
Interrupt channel. If not set, L2CAP_PSM_HID_INTR will
descriptor This required binary blob is the HID descriptor contain-
ing information about reports the device will produce,
and obtained via SDP.
reconnect If this boolean value is set, and is true, then the
bthidev driver will initiate reconnections to the remote
device when no connection is present.
link-mode This optional string represents the link mode of the
baseband link, and may be one of `auth', `encrypt', or
When the bthidev driver has configured its children, it will initiate a
connection to the remote device. If this fails and the reconnect flag is
not set, it will then wait for the device to initiate the connection.
