* This file initializes the different components of the whole BLE stack. This inlucdes link level,
* HCI, security, etc...
* This file has been copied from lib/sdk/Applications/EvKitExamples/BLE_fit/stack_fit.c
* NOTE: Different stack_*.c files in the SDK initialize different components. We have to
* be very carefull to intitialize all needed components here. Think e.g. SecRandInit() ...
* Many components are related to the role of the device. Different components need to be
* initialized for central and peripheral roles.
