Modify shutdown due to BLE API change



The module is updated to comply with the changes to BLE API regarding correct

shutdown functionality. The following changes are introduced to ble-nrf51822:



* Calls to the old static function shutdown in Gap, GattClient, GattServer and

SecurityManager are removed.

* The cleanup function in Gap, GattClient, GattServer and SecurityManager is

renamed to `reset()` and made public.

* The static references inside nRF5xGap, nRF5xGattClient, nRF5xGattServer and

nRF5xSecurityManager to objects of their own class are moved to nRF5xn.

* The static getInstance accessors in nRF5xGap, nRF5xGattClient,

nRF5xGattServer and nRF5xSecurityManager are removed and their functionality is

moved to the implemented virtual accessors in nRF5xn i.e. getGap(),

getGattClient, etc.

* A static function Instance is added to nRF5xn class to make the transport

object accessible across the module.
