Commit 344062ae5b intended to protect the
client list for AsyncEventSource from concurrent access by wrapping
accesses with locking. However, this introduces a self-deadlock scenario
if application code in the onConnect callback (now called with the
client list lock held) tries to broadcast a message to existing
connections in the same AsyncEventSource (for example, to alert of a
new incoming connection). The broadcast call tries to take the lock but
blocks because the lock is already taken, by the same task, before
calling the callback. Fixed by making use of the AsyncWebLockGuard class
which is tailor-made to address this scenario.

For Websocket added: void handleHandshake(AwsHandshakeHandler handler)
For EventSource added: void authorizeConnect(ArAuthorizeConnectHandler cb);
Auth example and modifications. Tested on ESP8266 and ESP32 platforms

* using Container instead ofdirect pointers list manipulation
* fixed different type of virtual methods.
* Fixed typo in conditional
* Renamed ListArray to LinkedList
* Const reference to String as method parameters to prevent additional copy and memory allocation when String passed by value
* fix 'min' redefinition
* removed #include <iterator>
begin/end methods it's enough for 'for( : )' loop
count() renamed to length()
spacing fixing
