7d2d73d8fc Fix pairing when already in progress.
If pairing is requested before performing an action on a protected attribute pairing could fail due to already being in progress.
This fix will wait for the result of the pairing process before proceeding with the action.

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.

2386a8a68a Retrieve attributes with 16bit uuid if 128bit fails.

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.

0957d7f6ad The latest versions of IDF include a new esp_timer library that seems to be incrementing the task notification values in unexpected places depending on other tasks in operation.
This causes task blocking to fail in client operations leading to exceptions and crashing.

This is a workaround for this situation and will need to be reworked properly in the future.

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());
}

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.

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.

39a3a63f80 Fix attributes not found with 16/32bit UUIDs.
* 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.
