If a connection event was sent but failed to establish then the disconnect
callback would be triggered when the application was not yet informed of the connection.
* Cleanup logs and add comments.
* 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 BLE_HS_EBUSY return code was causing the application to hang when starting scan as
occasionally the code would not change, resulting in an infinite loop.
This patch handles the return code more appopriately and removes the loop.
Additionally a race condition would sometimes allow the code to execute past the conditional checks
and clear the advertised device vector while a scan was active and writing to it causing an exception.
This has been hopefully corrected by only clearing the vector if the return code from starting the scan is 0.
* Some peripherals will advertise 16/32bit UUIDs but when queried for their handles
they do not convert the UUID to 128 bit locally and will return attribute not found.
This patch will query the peripheral a second time with a 128bit converted UUID.
- This changes NimBLERemoteCharacteristic::subscribe and NimBLERemoteCharacteristic::registerForNotify functionality
such that the notification callback will always be set.
Additionally these methods will always return true unless the descriptor write fails.
This allows for notifications to trigger the callback when a peer device sends them and does not have a CCCD.
Also it should not be flagged as a failure if the CCCD does not exist.
It should only be flagged when an acutal write operation fails.
* Fix for random notify crash in ISR context
Tested for stability over 30 minutes with a daisy chain of 3 esp32

* Adds functionality to advertise for a set duration, similar to NimBLEScan::start.
The first parameter being the duration (in seconds).
The second parameter is a pointer to a callback function that is invoked when advertising stops.
* NimBLEAdvertising::isAdvertising method added, returns true if advertising is currently active.
* These methods were noop's and are now removed due to lack of usefulness and advertisment space consumed if used.
Applications can still manually set these values if desired using NimBLEAdvertisementData::addData.
* 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.
* Add support for getting multiple services data from advertisments.
* Adds new methods for getting advertised service data and UUIDS.
- getServiceData(index), gets the service data by index value.
- getServiceData(NimBLEUUID), gets the service data by UUID.
- getServiceDataCount(), gets the number of services with data advertised.
* Templates added for getServiceData(index) and getServiceData(NimBLEUUID)
to be able to specify the data type returned by these methods
Example:
getServiceData<uint32_t>(NimBLEUUID("ABCD");
* Also added:
- getServiceUUID(index), gets the advertised service UUID by index value.
- getServiceUUIDCount(), gets the number of advertised services.
Server: Add onSubscribe() callback for characteristics.
Adds a new method to NimBLECharacteristicCallbacks that gets called when a client
changes it's subscription status.
* Remove NimBLE2902 class.
As the NimBLE2902 class usefulness was only related to callback functions that were replaced
by the NimBLECharacteristicCallbacks:onSubscribe() method this removes the NimBLE2902 class and
moves all subscription handling to NimBLECharacteristic.
* Update documents and examples to reflect this change.
* Add getSubscribedCount() to get the number of subscribed clients.
Added alternative characteristic read/write callbacks that carry the connection description information.

Author: lknop <lknop@users.noreply.github.com>
* Get service handles on server start
* remove service + indicate service changed
* Reset gatt services when no connections active and services changed.
* NimBLEServer::createService can now be used any time and will send service changed
indication if server was already active.
* Add ability to remove advertised serviceUUIDS
* Adds addService() method to server to be allow user to re-add a service previously removed
* Add destructior to NimBLEServer, NimBLEService and NimBLECharacteristic to release allocated resources.
