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.

393e1966c7 Avoid exceeding maximum container size
This issue would likely be triggered when automatically
merging multiple requests into a single one while having
their size exceed 1044456 bytes like SaveFilePartRequest.

This commit avoids such issue by keeping track of the
current size, and if it exceeds the limit, avoid merge.

33ce702ab9 Pre-pack outgoing TLMessage
This has several benefits:
- The message can be resent without re-calling bytes(),
  which for some requests may be expensive.
- Converting requests to bytes early lets us detect
  errors early, such as OverflowError on bad requests.
- Containers can't exceed 1044456 bytes so knowing their
  length is important. This can now be done in O(1).

But also several drawbacks:
- If the object is modified the bytes won't reflect this.
  This isn't an issue because it's only done for in msgs.
- Incoming messages can no longer be reconverted into
  bytes but this was never needed anyway.

4ab5c7d92d Fix reconnect sentinel when not reconnecting in send_loop
It would cause issues with the debug logs, since it assumes it's
a TLMessage, which have an .obj attribute. Second, the send_loop
is also smarter regarding reconnects (since OSError often occur
due to not being connected at all, namely ConnectionResetError).

e36aff51dd Raise ConnectionError when sending without connection
Otherwise the program could potentially block on await client(...)
since this has no timeout (unless asyncio.wait_for() was used) and
would give no further hint that the program was halted there.
