1b0abd273f [BREAKING] - Remove ignore list.
This removes the ignore list feature as it can be implemented by the application if desired.
The scan will now ignore any device we are connected to already by checking for any connected client with the same peer address.

5f2730de02 Revert #724e1a7 and replace with stack checks.
Replaces `NimBLEDevice::setConnectionInProgress` and `NimBLEDevice::isConnectionInProgress()` with lower level checks to avoid potential incorrect state reporting.
`NimBLEClient::connect` will instead call `NimBLEScan::stop` if it stopped the scan to release any resources waiting, the call the callback if set.

fbbcfadc0c Refactor client connection establishment and client deletion.
* Removes the connection established flag as it should not be necessary.
* Deleting the client instance from the `onDisconnect` callback is now supported.
* `NimBLEDevice::deleteClient` no longer blocks tasks
* Adds a new `Config` struct to `NimBLEClient` to efficiently set single bit config settings.
* Adds `NimBLEClient::setSelfDelete` that takes the bool parameters `deleteOnDisconnect` and `deleteOnConnectFail`
  This will configure the client to delete itself when disconnected or the connection attempt fails.
* Adds `NimBLEClient::setConfig` and `NimBLEClient::getConfig` which takes or returns a `NimBLEClient::Config` object respectively.

* Reword `BLE_HS_EAPP` error string to be more accurate.

7bd7b1dfc2 Workaround for bug in NimBLE stack when connect re-attempt enabled.
Connect reattempt does not pass the arg parameter correctly and the disconnect event will have no client pointer in the argument.
This finds the client from the connection handle to compensate.

38e764d157 Add asyncronous client connect and MTU exchange.
* Adds parameters `asyncConnect` and `exchangeMTU` to `NimBLEClient::connect`, default values work as the original connect method.
* * `asyncConnect`; if true, will send the connect command and return immediately with a true value for successfully sending the command, else false.
* * `exchangeMTU`; if true will send the exchange MTU command upon connection, otherwise not and the application can choose to do this later via the `exchangeMTU` method.
* Adds `onMTUChange` callback to `NimBLEClientCallbacks`
* Add `NimBLEDevice::getConnectedClients()` which returns a vector of pointers to the currently connected client instances.
* Calling `NimBLEClient::connect` will no longer cancel already in progress connections.

724e1a7083 Fix endless loop when calling scan start from scan end callback.
When attempting to connect and the scanner is running `NimBLEScan::stop` is called to stop it
which then calls the `onScanEnded` callback. If the app then starts the scan again in this
callback an endless loop will be created.

This change prevents the endless loop by setting a flag in `NimBLEDevice` that is checked before
starting a scan while a client is trying to connect.

* Adds `NimBLEDevice::setConnectionInProgress` and `NimBLEDevice::isConnectionInProgress` functions.

91210b8610 [BREAKING] Refactor attributes
Refactor attributes to reduce code duplication and improve maintainability.

* Add attribute base classes to provide common code.
* Add const where possible to functions and parameters.
* `NimBLECharacteristic::notify` no longer takes a `bool is_notification` parameter, instead `indicate()` should be called to send indications.

6279817143 [BREAKING] Refactor NimBLEAddress - use NimBLE core representation.
This simplifies the NimBLEAddress code by directly using the NimBLE core `ble_addr_t` type to hold the address
and allows using NimBLE core functions and macros to replace code in some methods.

* `getNative()` replaced with `getBase()` and now returns a pointer to `const ble_addr_t` instead of a pointer to the address value.
* Adds `isNrpa()` method to test if an address is random non-resolvable.
* Adds `isStatic()` method to test if an address is random static.
* Adds `isPublic()` method to test if an address is a public address.
* Adds `isNull()` methods to test if an address is NULL.
* Adds `getValue()` method which returns a read-only pointer to the address value.
* Adds `reverseByteOrder()` method which will reverse the byte order of the address value.
* `equals()` method and == operator will now also test if the address types are the same.
* Code cleanup.

Add NimBLEAttValue class. (#67)
This is a specialized container class to hold BLE attribute values.

- Removes the use of std::string previously used to store the values.
- Allows for setting/getting/notifying values from std::string, std::vector<uint8_t>, Arduino String, const char*, and uint8_t buffers.
- Has operators retrieve the value as std::string, Arduino String, std::vector<uint8_t>, uint8_t* or char pointers.
- Includes iterators and subscript/random access operator.
- Introduces a max length parameter to the creation of server characteristics/descriptors to limit the size of the memory footprint.
- Nearly Seamless integration with existing code.
- Adds a config option to enable/disable timestamp storage when the value is updated.
- Adds a config option to specify the initial size of the value container if not specified in the constructor.

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());
