* Handle the return codes from ble_gap_connect to take proper actions for different codes.
* Improve client event handling to accomodate delayed PDU responses.
* Use connection ID as a replacement for the isConnected flag. Also check if a task is waiting for
results instead of the waitingToConnect flag.
* Adds a disconnect timer so that calling disconnect will start a timer for the connection
supervision timeout time + a small delay. When this expires it will reset the host if a disconnect event
does not occur in this time. This is added as a workaround for the occasional situation
when the controller does not send an event after the disconnect command.
* The type is available in the NimBLEAddress parameter, no longer needed separately.

* Add clearAll parameter to deinit()
Adds the ability to clear all resources consumed during BLE operation when deinitializing and shutting down BLE.
Useful when BLE is used intermittently or in a task that initializes, performs operations then deinitializes.
By setting the clearAll parameter to true all created BLE objects will be deleted, freeing the memory for other tasks.
Warning: This will invalidate any pointers that may be referencing the deleted objects.
* Add bool deleteCallbacks parameter to NimBLEServer::setCallbacks, if true (default) will delete the callback class when server is destructed.
* Delete scan results when scan is destructed.
* NimBLEClient::disconnect() was setting the connected flag to false before the disconnection occured.
* NimBLEDevice::deleteClient() was not waiting for disconnection if it was already in progress.
* Client gap event handler was releasing the connection event semaphore when it should not.
* Add NimBLERemoteCharacteristic::getValue(time_t *timestamp = nullptr) to get the latest remote characteristic and (optionally) it's timestamp.
* Added a timestamp to NimBLEAdvertisedDevice for the moment a device was scanned
Previously we used createServer() to get a reference to the server instance.
This was problematic when using advertising only as it would create a server
when starting advertising. This prevents that and provides better semantics.
This allows NimBLE options in menuconfig to reduce code size based on
the roles selected (scan/advertising/central/peripheral).
Significant code space can be saved by removing unnecessary roles for the application.
