8a787e90c2 Remove send/recv locks 
There is only one method sending and one method receiving,
so it doesn't make sense to lock-protect those operations.

485ce5ca3b Ignore padding on server messages instead warning 
There's 12..1024 padding for the MTProto 2.0 protocol, and
the length of the message can be used to determine how much
must be read on rpc_results. However this random padding
can be safely ignored.

be279ce3f5 Make TLMessage always have a valid TLObject 
This simplifies the flow instead of having separate request/body
attributes, and also means that BinaryReader.tgread_object() can
be used without so many special cases.

Lonami Exo
f7e8907c6f Create RpcResult class and generalise core special cases 
This results in a cleaner MTProtoSender, which now can always
read a TLObject with a guaranteed item, if the message is OK.

adfe861e9f Create a self-contained MTProtoState 
This frees us from using entire Session objects in something
that's supposed to just send and receive items from the net.

e469258ab9 Create a new MTProtoSender structure and its foundation 
This means that the TcpClient and the Connection (currently only
ConnectionTcpFull) will no longer be concerned about handling
errors, but the MTProtoSender will.

The foundation of the library will now be based on asyncio.

2b9babb30f Handle GzipPacked lost requests & possibly fix reading normal 
Reading normal "lost" requests didn't .seek(-4) to read the TLObject
again. Now it has been slightly refactored to seek back always and
only seek forward when needed (e.g. rpc error).

The .confirmed is now a threading.Event to avoid the sleep(0.1).

RPC errors have been moved inside the request so they're not
raised on a background thread anymore.
