Changes all functions that accept a time parameter to use milliseconds instead of seconds.
* Adds duration input to NimBLEDevice::startAdvertising and NimBLEServer::startAdvertising.
Adds support for advertising and connections with coded/2M PHY's.
Adds new classes `NimBLEExtAdvertising` and `NimBLEExtAdvertisement`.
When extended advertising is enabled the original advertising classes become unavailable and the new classes must be used.
Changed some return values for advertising methods for consistency with the new classes methods.
* Sets macros to allow compiling when Central role is enabled and Observer disabled, or Peripheral enabled and Broadcaster disabled.
* Adds a macro definition for CONFIG_NIMBLE_CPP_IDF to enable different include paths/functionality for IDF / Arduino.
This reverts a previous change @2e1d78ff that caused compiling/linking errors due to the redefinition of btInUse() when another linked library uses the Arduino bluetooth code.
* Add the option to change the scan filter mode through NimBLEDevice::setScanFilterMode
* Add the option to change the scan filter cache size through NimBLEDevice::setScanDuplicateCacheSize
* Refactor nimconfig to make it for doxygen use only.
Previously when the host reset while scanning (if active prior) it would be restarted automatically.
This caused errors for some applications and has been removed since the event invokes the scan
ended callback for the app to take action. Instead scanning will now only be restarted if the duration
was indefinite and a callback was set for the advertisment events, this use case is less likely to have
a scan ended callback.
Advertising (if active prior) would be started without regard to it's previous state.
This has been corrected to only start advertising again if it was advertising for an idefinite time.
While deleting the client attribute database, if a notification occurs there is a possibility of
concurrency causing an exception. This fixes that by setting a flag before calling disconnect in
the deleteClient function to prevent processing further notifications.
This change is needed to allow any tasks that were stopped during a host reset to finish
before resuming from the re-sync. This would occasionally result in a LoadStoreError exception
if not done.
* 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.
