Import the acceptor code from Cowboy

Modules were renamed. The 'cowboy_' prefix became 'ranch_'.
At the same time, ranch_ssl_transport became ranch_ssl,
and ranch_tcp_transport became ranch_tcp, because appending
'_transport' felt a bit redundant considering SSL and TCP
clearly are transports.

One test has been added to make sure everything is working.
