This patch set integrates shared/gatt into the core bluetoothd for GATT
client role. This set makes the following changes:
- Made small fixes and added getters to support legacy code paths.
- Removed explicit primary and included service discovery logic within
src/device in favor of initializing a bt_gatt_client. This includes
deferring service/profile registration until the bt_gatt_client is ready,
and proper handling for "Service Changed" events using gatt_db's service
added/removed callbacks. When new services are added during a connection,
the profiles are explicitly probed. The code still creates and maintains
instances of struct gatt_primary to support legacy plugins.
- Introduced gatt-callbacks.h. This defines callbacks that are invoked when
services are removed, the gatt-client becomes ready, and when the connection
is closed. These callbacks are similar and parallel to the existing ones
defined in attio.h and provide an alternate solution for shared/gatt.
gatt-callbacks.h is not meant to be the long-term solution and these may
perhaps be better served by new GATT specific functions added to the
btd_profile/btd_service framework.
- Rewrote the built-in GAP/GATT profile. It no longer handles the GATT
service and does no MTU exchange (which was racy and did not belong in a
profile in the first place) as these are handled by shared/gatt-client.
Renamed the profile to profiles/gap as it only handles the remote GAP
service and added handling for the "Device Name" characteristic. The profile
now uses gatt-callbacks instead of attio and bt_gatt_client/gatt_db instead
of GAttrib.
