ad963fd23e Don't clear pending_ack on disconnect 
Upon reconnecting, we must make sure to send all `pending_ack`,
or Telegram may resend some responses (e.g. causing duplicated
updates).

7523869875 Except IOError and not ConnectionError 
PySocks' errors do not subclass ConnectionError so the library
was unnecessarily logging them as unexpected, when any IOError
was actually expected.

04ba2e1fc7 Revert disconnect() to be async again (#1133) 
It's the only way to properly clean all background tasks,
which the library makes heavy use for in MTProto/Connection
send and receive loops.

Some parts of the code even relied on the fact that it was
asynchronous (it used to return a future so you could await
it and not be breaking).

It's automatically syncified to reduce the damage of being
a breaking change.

c8f16a4e89 Fix a couple of inconsistencies in the public interface (#1102) 
* Create `_NOT_A_REQUEST` when needed. Currently, modifications    
  in the raised exception would be "global".    
* `retries` parameters were actually attempts. This has been fixed    
  to actually be the amount of retries, so 0 now means don't retry.    
* Helper function to deal with retries instead of using a range with    
  different styles every time.

95cf873bad Don't mark the user as connected until successfull connection 
The idea behind distinguishing between the user being connected and
the actual connection having been made was to support retries while
the user decided to connect, even if the connection wasn't made yet.

The problem is that _user_connected is used directly to tell whether
the sender is connected or not which will be wrong if an exception
occurs on the initial connection. Since the logic retry isn't used
there we can simply mark as connected once a successfull connection
is made.

091180b32d Except CancelledError in MTProtoSender send/recv loop 
This way, the tasks should not end with the cancelled exception
which should get rid of the warning if any.

7dece209a0 Cancel tasks on reconnect instead of awaiting them 
This prevents us from locking forever on any task that doesn't
rely on cancellation tokens, in this case, Connection.recv()'s
_recv_queue.get() would never complete after the server closed
the connection.

Additionally, working with cancellation tokens in asyncio is
somewhat annoying to do.

Last but not least removing the Connection._disconnected future
avoids the need to use its state (if an exception was set it
should be retrieved) to prevent asyncio from complaining, which
it was before.
