Thomas Zimmermann 74ddad6337 Bug 1197877: Remove |INIT_AT| macro from Bluetooth, r=btian
|INIT_AT| works around missing compiler features for gcc before
version 4.7. All B2G targets have been lifted to gcc 4.8, so the
workaround is not required any longer.

//
// Protocol handling
//
// |BluetoothDaemonProtocol| is the central class for communicating
// with the Bluetooth daemon. It maintains both socket connections
// to the external daemon and implements the complete HAL protocol
// by inheriting from base-class modules.
//
// Each |BluetoothDaemon*Module| class implements an individual
// module of the HAL protocol. Each class contains the abstract
// methods
//
// - |Send|,
// - |RegisterModule|, and
// - |UnregisterModule|.
//
// Module classes use |Send| to send out command PDUs. The socket
// in |BluetoothDaemonProtocol| is required for sending. The abstract
// method hides all these internal details from the modules.
//
// |RegisterModule| is required during module initialization, when
// modules must register themselves at the daemon. The register command
// is not part of the module itself, but contained in the Setup module
// (id of 0x00). The abstract method |RegisterModule| allows modules to
// call into the Setup module for generating the register command.
//
// |UnregisterModule| works like |RegisterModule|, but for cleanups.
//
// |BluetoothDaemonProtocol| also handles PDU receiving. It implements
// the method |Handle| from |DaemonSocketIOConsumer|. The socket
// connections of type |DaemonSocket| invoke this method
// to forward received PDUs for processing by higher layers. The
// implementation of |Handle| checks the service id of the PDU and
// forwards it to the correct module class using the module's method
// |HandleSvc|. Further PDU processing is module-dependent.
//
// To summarize the interface between |BluetoothDaemonProtocol| and
// modules; the former implements the abstract methods
//
// - |Send|,
// - |RegisterModule|, and
// - |UnregisterModule|,
//
// which allow modules to send out data. Each module implements the
// method
//
// - |HandleSvc|,
//
// which is called by |BluetoothDaemonProtcol| to hand over received
// PDUs into a module.
