b290ca9077 [NimBLEAdvertisementData] Add setServices methods for multiple UUID's
Adds:
- setPartialServices16
- setPartialServices32
- setCompleteServices16
- setCompleteServices32

Each takes an input parameter of std::vector<NimBLEUUID> to allow for advertising multiple services with a simple interface.

82524c80e3 [NimBLEScan] Use controller duplicate filter and add max result limit.
* Adds setMaxResults to NimBLEScan to limit the number of advertised devices stored.
  If set to 0 no devices will be stored in memory and only the callback will be invoked.
  If set to 0xFF (default) stored devices will be unlimited. Any other value will be the limit.

* Uses the controller to filter duplicate devices from the scan results when wantDuplicates == false.

9527c41486 Refactor advertisedDevice (#181)
* Stores complete advertisement payload and only performs parsing on demand. The advertised data is no longer parsed automatically as it is discovered, instead it will be parsed to find only the data requested by the user application when it makes a call to do so. This saves processing time and approximately 2.4k in flash size, with the new methods listed below included.

Add more advertised device field methods:
* Adds haveAdvInterval/getAdvInterval - checks if the interval is advertised / gets the advertisement interval value.

* Adds haveConnParams/getMinInterval/getMaxInterval - checks if the parameters are advertised / get min value / get max value.

* Adds haveURI/getURI - checks if a URI is advertised / gets the URI data.

* Adds haveTargetAddress/getTargetAddressCount/getTargetAddress(index) - checks if a target address is present / gets a count of the addresses targeted / gets the address of the target at index.

026864e031 Set Client connect/disconnect data before stack calls.
Connect should set m_pTaskData before calling ble_gap_connect in case of an early event.

Disconnect should check if the timer has already started before starting the timer so it does not reset it.
The timer should also be started before calling ble_gap_terminate in case of an early event that would cause the timer to start
after disconnection, resetting the host unnecessarily.

c089eab595 Check connection status when returning in NimBLEClient::Connect.

6ee1cc236a Advertising start: add return status, use more verbose logging.

b064cc65d4 Find characteristic end handle using the next characterisic handle.

372c79a6b8 Only start scan/advertise when host re-synced if duration was indefinite.
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.

28573f5abe Fix crash in NimBLEDevice::deleteClient when notification arrives.
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.

b807321d1b NimBLEDevice::onSync should call taskYIELD() before returning.
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.

4f4883d6ba Prevent notifications from triggering exception while deleting services.
If we client just connected and a notification comes before deleting services it could cause an exception
when accessing a vector that is being deleted. This will check the connection established flag before

28717c300a Fix client connect return code handling, add disconnect timer.
* 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.

8fe2766e01 Remove loop on BLE_HS_EBUSY in NimBLEScan::start
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.

36317e18db Allow subscribing to characteristics if CCCD does not exist on peer device.
- 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.
