Add extended advertising support. (#72)
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.

ccea428b9e Refactor include directives to use different paths for arduino/idf.
* 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.

[Server] Implement remove Characteristics/Descriptors. (#54)
This allows for adding and removing of characteristics and descriptors after initial setup of the server.
When used it will send a service changed notification to all clients.
The changes will not take effect until all clients have disconnected and advertising restarted.

d9d794ae40 [Server] Add ability to create static attributes.
This allows creating instances of services/characteristics and decriptors without
needing to call the parent createX() methods. This allows creation of the attibutes
within a class or other structure and the attributes can be linked to the parent by
calling the parent addX() method.

Additonally this increases the backward compatibility with the original bluedroid library
to further support user migration.

62d1f67d8b Add connection info class and access methods to server and client.
This adds the ability to access information about the current connection.
A new class was created to wrap the struct ble_gap_conn_desc with methods to retrieve the connection information.

Example server use:
```
for(auto i=0; i<pServer->getConnectedCount();i++) {
    NimBLEConnInfo connInfo = pServer->getPeerInfo(i);
    printf("Connected client %d info:\n", i);
    printf("Peer address: %s\n", connInfo.getAddress().toString().c_str());
    printf("Peer ID address: %s\n", connInfo.getIdAddress().toString().c_str());
    printf("Handle: %u\n", connInfo.getConnHandle());
    printf("Interval: %u\n", connInfo.getConnInterval());
    printf("Timeout: %u\n", connInfo.getConnTimeout());
    printf("Latency: %u\n", connInfo.getConnLatency());
    printf("MTU: %u\n", connInfo.getMTU());
    printf("Master: %s\n", connInfo.isMaster()? "true":"false");
    printf("Slave: %s\n", connInfo.isSlave()? "true":"false");
    printf("Bonded: %s\n", connInfo.isBonded()? "true":"false");
    printf("Authenticated: %s\n", connInfo.isAuthenticated()? "true":"false");
    printf("Encrypted: %s\n", connInfo.isEncrypted()? "true":"false");
    printf("Encryption Key Size: %u\n", connInfo.getSecKeySize());
}
```

Example client use:
```
if (pClient->isConnected()) {
    NimBLEConnInfo connInfo = pClient->getConnInfo();
    printf("Connection info:\n");
    printf("Peer address: %s\n", connInfo.getAddress().toString().c_str());
    printf("Peer ID address: %s\n", connInfo.getIdAddress().toString().c_str());
    printf("Handle: %u\n", connInfo.getConnHandle());
    printf("Interval: %u\n", connInfo.getConnInterval());
    printf("Timeout: %u\n", connInfo.getConnTimeout());
    printf("Latency: %u\n", connInfo.getConnLatency());
    printf("MTU: %u\n", connInfo.getMTU());
    printf("Master: %s\n", connInfo.isMaster()? "true":"false");
    printf("Slave: %s\n", connInfo.isSlave()? "true":"false");
    printf("Bonded: %s\n", connInfo.isBonded()? "true":"false");
    printf("Authenticated: %s\n", connInfo.isAuthenticated()? "true":"false");
    printf("Encrypted: %s\n", connInfo.isEncrypted()? "true":"false");
    printf("Encryption Key Size: %u\n", connInfo.getSecKeySize());
}
```

[NimBLEServer] Support duplicate characteristics (#36)
* Add method to get all characteristics of a service

* Added method on NimBLEDescriptor to get the value out as a std::string

* Added methods to get things by handle where UUID could be used already.

* Added helper methods for getting a list of characteristics with a given UUID and service

* Demote the warning log for adding duplicate characteristics to a debug level log.

* Add methods to get services and characteristics using UUID + index

Add duration and callback parameter to NimBLEAdvertising::start
* 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.

Add clearAll parameter to deinit() (#22)
* 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.

Server: Add onSubscribe() callback for characteristics. (#21)
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.

Add feature: remove service (#17)
* 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.

03cb7b21d9 Conditionally compile code for specific roles.
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.
