asyncio: SSLProtocol and _SSLProtocolTransport are heavily coupled so need merging

Analyzing how asyncio internals work, I was puzzled by a role of asyncio.sslproto._SSLProtocolTransport, its domain relation to asyncio.sslproto.SSLProtocol, and why the latter is a thin shell that just redirects all function calls back to SSLProtocol.

After spending some time matching the ends I found out that both classes are actually two faces of the same object. One is the plaintext side looking at user-supplied Protocol, and another is the cyphertext side looking at the actual data source. Thus, they are extremely coupled and cannot be seen independently.

As a result, these two objects need to be turned into two interfaces of a single asyncio.sslproto.SSLProtocol. In other words:

class _SSLProtocolTransport(transports._FlowControlMixin, transports.Transport):
    ...

class SSLProtocol(protocols.BufferedProtocol):
    ...

should be converted into:

class SSLProtocol(protocols.BufferedProtocol, transports._FlowControlMixin, transports.Transport):
    ...

for easier understanding of what's happening and elimination of an excessive entity that requires understanding.
