Modify shutdown API and functionality



Modify the shutdown API to remove the static shutdown function in Gap,

SecurityManager, GattClient and GattServer. Futhermore, remove the static

references to Gap, SecurityManager, GattClient and GattServer objects inside

their own classes. The cleanup method is renamed to `reset()` and made public.

Finally, additional functionality is added to the reset implementation in

Gap.
