Generic implementation of the GAP class. It allows porters to have a working Gap
implementation by implementing the following abstraction layer primitives:
- pal::Gap: Adaptation for GAP related primitives.
- pal::EventQueue: simple interface to the inner event queue of the stack.
pal::SimpleEventQueue can also be used as an implementation.
- pal::GenericAccessService: Accessors to the Generic Access Service present in
the GATT server.
This changes introduce a platform adaptation over ATT/GATT that can be implemented by porter.
Unlike the GattClient interface, the ATT/GATT adaptation is simple, follow closely the Bluetooth specification and won't change over time.
Implementation of the GattClient interface is realized by the class GenericGattClient which accept in input a pal::GattClient.
This change will also free design space once adopted by partners, addition to the GattClient interface won't require partner support.
