Add onShutdown to register callbacks



Add an onShutdown() function to Gap, GattClient, GattServer and

SecurityManager. The callbacks are added to a private callback chain in each of

the instances. The callbacks will be executed inside each object's reset()

function BEFORE the state of the instance is cleared. The developers of the

platform-specific implementation must call the parent class' reset() function

for the callbacks to be executed.



Finally, an onShutdown() function that returns the shutdown callchain is added

to allow detaching callbacks.
